FAQ
Does this fit all 2001–2016 Duramax engines?
Yes—LB7, LLY, LBZ, LMM, and LML. Verify your rod is stamped “B” to use the CB-1805 family.
What does .25 mm undersize mean?
It fits crank journals ground 0.25 mm (.010") under standard. Always measure and choose the size that matches your crank.
Is this sold as a single pair or full set?
This listing is for one pair (two shells) per rod. A complete V8 requires eight pairs, or choose the CB-1805P-.25MM (8) set above.
Why P-Series for performance?
P-Series uses a hardened steel back, reduced overlay thickness, and high crush to handle high RPM and rod-bore close-in.
