6745 ARC Billet Rod Animal Stroker 4.500X.708
4.500" Animal "Stroker" Rodwithbearing inserts. ARC's stroker rod is designed to give you the most rod length you can get with the PPM Billet Animal +1.00'' deck block with an ARC 6579-C Billet Crankshaft. Uses the PPM designed JE style pistons without cutting off the top. This piston uses .708" wrist pin which is a much more durable. A longer rod lessens the rod angle at half-stroke, which decreases stress on the rod and piston to wall pressure. This provides considerable improvement in durability and performance over the stock setup. Bolts and bearings are included.
Rod bolt torque: 170 in/lbs lubricated
