Common Issue With The 6.6L LBZ/LMM (and what we do to fix it) – Pistons – The LBZ, the holy grail of all Duramax engines.

While there aren’t too many problems with this engine platform the pistons are one failure point. The wrist pin bushings fail, so we updated the pistons to rid them of the press in bushing for the wrist pin.

If there’s an existing issue with any engine platform, we fix it. That’s why our moto is: Stock Is Not An Option.
