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.

Looking at a couple of upgrades that would make it more my truck and what I want.

Ceramic Coating - DONE 3/24/2020 by Ceramic Pro

  • Clay bar service (strips all the impurities that were on your car previously)
  • Buff wax
  • blackout of exterior trim
  • 5 Layers of Ceramic Pro 9H
  • 1 Layer of Ceramic Pro Light Applied as a Top Coat
  • 1 Layer of Ceramic Pro 9H on Rims and Plastic
  • 1 Layer of Ceramic Pro Rain on Front Side Windows and Windshield
  • Lifetime Warranty

Tow Mirrors

GM OEM Tow Mirrors (boring.. no front facing turn signal) and run about $400 each (GM Part# 15904035 right & 15904034 left). Word on the reviews is they still shake just like an after market mirror does so not sure its worth the high price tag for GM Camper Mirrors.
