Warning: Last items in stock!
The strongest rod assembly from Chevy is a forged steel heavy duty rod that was originally used in the Mark IV 427 L-88 and ZL1 motors PN # 3969804 they are magnafluxed and shot peened at the factory and come with super strong 7/16" boron rod bolts PN 3969864 which have also been shot peened and magnafluxed at the factory. These are color coded green to differentiate them from the other dimple rods used in the LS-6 and LS-7 454s which are color coded white. These rods can be used in all Mark IV, V, and VI engines but are balanced for L-88 and ZL-1 427 engines, so if you are going to use them with something else they should be rebalanced with the pistons you are going to use.
