Description
ARC's +.237 stroker rod was designed specifically to provide the most rod length you can get with the stock block and either: an ARC 6580 Billet Crankshaft, or a Briggs and Stratton "Raptor" crankshaft. This rod uses the shorter compression height Wiseco or a JE-style piston with approximately .090" cut off the top. This piston uses a smaller, .490" wrist pin which is a much lighter combination than stock options. 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.
