  • Welcome to Gear Crushers!

    So what the heck is Gear Crushers all about?  We are about loving more than just offroad or just street or just motorcycles.  We love all of it!  Too many clubs are focused on one thing like Jeeps or Motocross but we like everything.  We believe we can love more than just one focus.  Let's focus on all that is cool and crush them gears.

    drag.jpg          jeep-atv.jpg

    This site is dedicated to anyone who enjoys the sound of an engine, the smell of fuel burning, the adrenaline of tackling challenges while crushing those gears.

    We are not biased towards one type of vehicle, make or model. We can appreciate the passion no matter what you are working on, driving, admiring, polishing, designing.

    Gear Crushers are for those of us that want to break the mold and have one site that has something for everyone since many of our passions can easily cross. An engine or trans or axle or tires etc may work on something else in a completely different group.  Troubleshooting could also be similar.

    I don’t find it fair that we have to choose “exactly” what we have to be on different websites or groups even though our passion may stretch amongst multiple types of vehicles so here you go. Gear Crushers covers anything that runs fuel.  Community driven. Cool logo. Non-biased fun.=

    Enjoy as we keep improving the site!  We are under construction since our site was hacked and destroyed.  We moved to a more solid website and its now also encrypted using an SSL cert so we should have a better shot at keeping up and running.  We also learned to back up the site so nightly backups are happening now.

      Although all of Chevrolet's siblings of the period (Buick, Cadillac, Oldsmobile, Pontiac, and Holden) designed their own V8s, it was the Chevrolet 305 and 350 cu in (5.0 and 5.7 L) small-block that became the GM corporate standard. Over the years, every American General Motors division except Saturn and Geo used it and its descendants in their vehicles.

      In 1991, GM created a new-generation small-block engine called the "LT1 350", distinct from the high-output Generation I LT-1 of the 1970s. It displaced 5.7 L (350 cu in), and was a 2-valve pushrod design. The LT1 used a reverse-flow cooling system which cooled the cylinder heads first, maintaining lower combustion chamber temperatures and allowing the engine to run at a higher compression than its immediate predecessors.

      LT1 engine was used in:

      Y-body:

      • 1992–1996 Chevrolet Corvette C4

      F-body:

      • 1993–1997 Chevrolet Camaro Z28, B4C and SS
      • 1993–1997 Pontiac Firebird Formula, Trans Am, and Firehawk

      B-body:

      • 1994-1996 Buick Roadmaster
      • 1994–1996 Chevrolet Caprice
      • 1994–1996 Chevrolet Caprice Police Package
      • 1994–1996 Chevrolet Impala SS
      • 1994–1996 Chevrolet Caprice Wagon
      • 1994–1996 Buick Roadmaster Wagon

      D-body:

      • 1994–1996 Cadillac Fleetwood

      There were a few different versions of the LT1. All feature a cast iron block, with aluminum heads in the Y and F bodies, and cast iron heads in the B and D bodies. Corvette blocks had four-bolt main caps, while most other blocks were two-bolt main caps. Block castings remained the same between 2 and 4 bolt mains.

      The 92–93 LT1s used speed density fuel management, batch-fire fuel injection and a dedicated Engine Control Module (ECM). In 94 the LT1 switched to a mass airflow sensor and sequential port injection. A new, more capable computer controlled the transmission as well as the engine and got a new name: Powertrain Control Module (PCM). Where the ECM held its calibration information in a replaceable PROM chip, the 94-95 OBD1 PCMs are reprogrammable through the diagnostic port.

      The LT4 was available on the following vehicles:

      • 1996 Chevrolet Corvette only when equipped with 6-speed manual transmission (includes all Grand Sports) (Production: 6,359)
      • 1997 Chevrolet Camaro SLP/LT4 SS 6-speed (Production: 100 for the U.S., 6 for Canada. There were 2 prototypes)
      • 1997 Pontiac Firebird SLP/LT4 Firehawk 6-speed (Production: 29)

      The LT4 was the special high-performance version of the new-generation LT1. It featured a slightly more aggressive camshaft profile, 1.6:1 aluminum roller rocker arms, lighter hollow intake valves and liquid-sodium filled exhaust valves, larger fuel injectors, performance crankshaft, higher 10.8:1 compression ratio and high-flow intake manifold (painted red) with extra material above the port available to allow port matching to the raised port LT4 cylinder heads. The LT4 was conservatively underrated at 330 hp (246 kW) and 340 lb⋅ft (461 N⋅m). It was introduced in the 1996 model year, for the last year of the C4 Corvette, and came standard on all manual transmission (ZF 6-speed equipped) C4 Corvettes. The engine was passed down to 1997 SLP Camaros SS and SLP Firehawks with 6-speed manual transmissions.

      For model year 1990, Chevrolet released the Corvette ZR-1 with the radical Lotus Engineering-designed double overhead cam LT5 engine. Engineered in the UK but produced and assembled in Stillwater Oklahoma by specialty engine builder Mercury Marine, the all-aluminum LT5 shared only the 4.4 inch bore spacing with any previous sbc engine. It does not have reverse cooling and is generally not considered a small block Chevrolet.

      The LT5 was available on the following vehicles:

      • 1990-1995 Chevrolet Corvette C4 ZR-1 equipped with 6-speed manual transmission (Production: 6,939). Although the LT5 was never used in another production GM vehicle, it did make its way into several Corvette concepts, race cars and even into a limited run of the Lotus Elise GT1.

      What do you use offroad to keep track of where you are going, where you've been?

      I've used GAIA for the trail riding I've done and its worked pretty good.  Is it perfect? No but I am running it on my iPhone (which you can also run it on any Android or iOS device with GPS) and so I don't need to have multiple charge ports (1 for a GPS unit, 1 for my phone)..  just keep it charged and hundreds of possible mounts for a phone versus a certain GPS unit.

      NOW the negatives, obviously an iPhone is more expensive (in many cases) than a GPS unit.  The function of the GPS unit is just for keeping you informed of where you are so more than likely it has more satellite antennas.  I've been one of those that thought for years, why would I waste money on a GPS unit when I can do all that on my phone.  Now I'm changing that tune to be more open about the idea.

      The community seems to all rave about vvmapping and a few others that require you have a Garmin unit if you want turn by turn instructions on the trails which could come in handy.

      If I decide to get a GPS unit it will be a Garmin and it has to be able to be portable (in case you break down, you could use the GPS unit to find your way to civilization and hopefully mark your spot that your down and broke so you can find your way back).

      vvmapping only supports the following GPS models

      • Dakota, Colorado, Montana, Monterra & Oregon (all model numbers for these)
      • DEZL (all model numbers for these)
      • DRIVE (including DriveSmart, DriveAssist, DriveLuxe, DriveTrack) (all model numbers for these)
      • eTrex: 20, 30, Legend C/CX/HCX, Vista C/CX/HCX, Venture HC; Touch; (must be color unit)
      • GPSMap 60, 62, 64, 66, 76, 78, 620, 640 (all in each model series, must be color unit)
      • GPSMap 276C, 376C, 378, 478 (these take special Garmin data cards, not the card we provide)
      • GPSMap 276CX
      • Nuvi & Nuvi Track (all model numbers for these)
      • Overlander
      • Rino 530 HCX and 6xx/7xx
      • RV (all model numbers for these)
      • Zumo (all model numbers for these)

      From my understanding the Garmin Nuvi models are not waterproof, so something to consider.  I've been leaning on a Garmin Montana but not sure yet.

      By wildweaselmi,

      I found this information pretty interesting and wanted to share with everyone else.

      A break down of the import/export business for vehicles is shown here

      Global_imports_and_exports_of_cars.png

      The OICA counts over 50 countries which assemble, manufacture or disseminate automobiles. Of that number, only 14 countries (list below) currently possess the capability to design original production automobiles from the ground up.

      • Australia
      • China
      • France
      • Germany
      • India
      • Iran
      • Italy
      • Japan
      • Malaysia
      • Russia
      • South Korea
      • Sweden

      Below are the top 20 motor vehicle producing countries (as of 2018).  I was very surprised to see how much more China is than everyone else.

      motor_producing_countries.png

      Best-selling brands produced in China

      According to China Association of Automobile Manufacturers (C.A.A.M), automakers in China delivered 28,226,616 passenger and light commercial vehicles in 2017. Volkswagen remained the best-selling brand followed by Honda. In 2017, Geely surprised everyone by rocketing to become the third best-selling brand in China and the top Chinese brand in the market. Korean and American brands suffered from lackluster sales with Hyundai dropping from the top ten and GM and Ford both falling below local Chinese brands. Below is a breakdown of the deliveries by brand.

      The best selling specific model in 2017 was the Wuling Hong Guang minivan made in partnership with SAIC-GM, formerly known as Shanghai General Motors Company Ltd. In fact, five of the top-15 models were produced by SAIC-GM. Volkswagen had three models in the top-15, including the number-two Lavida while Geely, Great Wall, and Guangzhou Automotive Corp (GAC) models accounted for several models on that list. Number three of the top-15 belonged to the Nissan Bluebird Sylphy/Sylphy, number four to the Haval H6 and number five to the VW New Santana.

      When the LBZ was introduced to replace the LB7, the LB7’s injector issues had long been solved and the overheating issues associated with the LLY were a thing of the past. This engine’s beefier block casting, stronger connecting rods, higher pressure common-rail fuel system and updated ECM arguably made it the most powerful, drivable, reliable and tunable Duramax to date. Right out of the box, the LBZ produced 360hp and 650 lb-ft of torque. During this time frame (’06-‘07), these numbers not only outperformed the 6.0L Power Stroke’s 325hp and 570 lb-ft, but they beat out the 325hp and 610 lb-ft figures put up by the 5.9L Cummins as well. The LBZ was also the first Duramax to be coupled to the six-speed Allison 1000 automatic, which proved capable of handling more power than the five-speed version that preceded it.

      Diesel enthusiasts longingly remember the LBZ as the last Duramax built before the modern day emissions crunch kicked in, which spawned pollution control technology that reduced fuel economy and greatly hampered long-term engine durability.  Arguably the most highly sought after Duramax ever built is the LBZ Duramax.

      • More meat exists in the lower section (big end) of the rod than what you’ll find on LB7
      • The beefier I-beam style rods bring more mass to the rotating assembly
      • Connecting rods were the strongest found in any Duramax up to that time
      • GM cast slightly more webbing into the main bearing regions of the LBZ’s gray-iron block for added horsepower and torque

      Unfortunately nothing is perfect and in this case the LBZ pistons weren’t up to the task of surviving in higher horsepower applications.  The cast-aluminum pistons are highly susceptible to cracking.  The LBZ piston’s use of wrist pin bushings is also believed by many to be a contributing factor in OEM piston failure, along with a thinner wrist pin being utilized.

      When a piston lets go, you definitely know it, as it’s accompanied by a nasty miss, excessive blow-by and smoke out the exhaust.

    8. My wife and I are freezing our asses off in our own home unless I crank the furnace up to 68 degrees which is crazy to think.  I remember as a kid we were never cold in the house but we always had a wood burner in the home (most of the homes it was in the basement).  It would get some warm in the house that windows had to be opened in the home in the middle of winter to let out some of the hot and let in some of the cool weather.

      So now I'm a grown up and freezing my ass off in this home that was built in the 60's I thought of applying the same thought process that worked when I was a kid.  Get a wood burner in the basement.

      5CAB6E7B-CC5A-4C69-9A40-5F2C5603580D.jpeg

      I originally wanted to replace the wood stove upstairs that came with the home since it doesn't put out a lot (or really any) heat.  Especially since we spend most of our time in the living room upstairs but when they came out to look at what we have they pointed out that we should stop using it Immediately.

      564AF8CD-23D8-4C18-A03F-7AB0F82F14E0.jpeg

      Apparently whoever put the wood insert in trimmed the outside of it with wood trim which is charred on the back from burning from the heat of the wood stove.  So in short, its about to start on fire like charcoal.  To correct the hearth that is too short, all the wood trim, wood mantle, etc I'm looking close to $10,000 so probably not going to happen.  My thought was to pull it out and put a gas stove/insert in its place so I don't have to do as much work.  The company I talked to said they could pull the stove out for $400 but some serious cost to fix everything.  That will have to be maybe next year.

      Since upstairs is a bust, concentrating on the downstairs which uses the same chimney so its directly below the living room. 

      0D028897-FC8A-483F-8524-7E353335E117.jpeg

      My thought is it would at least warm the wood floors in the winter and give the impression its warmer.  And we do know that warm air rises so there is a good chance it could heat most of the 1800 sq ft 1960 home on half basement and half crawl (the crawl space is below all the bedrooms)

      I was bouncing back and forth between a Lopi and a Blaze King for manufacturers of wood stove.  My parents has a Lopi wood stove and it was there favorite of all the brands they had but that was a long time ago before they started getting strict with emissions.

      Researching burn times and warranty information the Blaze King on paper is the clear winner so I chose a Blaze King Princess Insert which will get installed on the 23rd of January 2018 (brochure is attached along with manual)

      By wildweaselmi,

      So what the heck is Gear Crushers all about?  In short, we have so many passions that we couldn't pick just one.  We love all of it!  Too many websites and clubs are focused on one passion but we like everything.  We believe we can love more than just one passion.  

      How many times have you gone to a website and invested time in adding and contributing to the community to have them change or just call it quits.  Or you belong to a website that never gets updated.. yawn.  We are tired of being involved with communities / websites that the admins just don't keep up to date with patches or no involvement because the community has given up on them.

      We at Gear Crushers love everything and that isn't a passion that just goes away.  I don't want to have to join multiple different clubs because I enjoy different toys. Most everything is similar (engine, trans, suspension, etc). I enjoy not just offroad but street racing, boats, rv's, ATV's, Motocross, Motorcycles, etc..  This site "Gear Crushers" is exactly that.  We want to give a home for everyone.  They all have similarities that could benefit you or could benefit someone else.  Engines, Transmissions, Axles, etc..  but feel free to create your own club to advertise your site (events for your community).  People may be browsing Gear Crusher Clubs by location and could find that you are in their area.

      Also I think we have a kick ass logo that could be used by Bike, Car, Truck, Offroad, Boat communites..

      Let's focus on all that is cool and crush them gears.

      This site is dedicated to anyone who enjoys the sound of an engine, the smell of fuel burning, the adrenaline of tackling challenges while crushing those gears.

      We are not biased towards one type of vehicle, make or model. We can appreciate the passion no matter what you are working on, driving, admiring, polishing, designing.

      Gear Crushers are for those of us that want to break the mold and have one site that has something for everyone since many of our passions can easily cross. An engine or trans or axle or tires etc may work on something else in a completely different group.  Troubleshooting could also be similar.

      I don’t find it fair that we have to choose “exactly” what we have to be on different websites or groups even though our passion may stretch amongst multiple types of vehicles so here you go. Gear Crushers covers anything that runs fuel.  Community driven. Cool logo. Non-biased fun.
