Specs At A Glance

Good To Know

Q: Do I need to replace the crankshaft bearings separately? A: This kit contains the connecting rod and its bearing inserts; the main and crank bearings should be inspected and replaced if worn.

Q: Are these rods compatible with the stroker cranks? A: They are sized for stock stroke engines; aftermarket stroker cranks require different rod lengths.

Slight variation in finish or dimensions may occur between production runs, and fit can depend on serial number, so confirm compatibility before ordering.
