About This Product
S&S forged stroker piston kit. The pistons are +.040 inch oversize for 3-7/16 inch or 3-1/2 inch cylinders. They suit 1941 to 1984 Big Twins running stroker flywheels. Compression ratio reaches 10.8 to 1 with a 4-3/4 inch stroke. The kit is sold as a set and includes wrist pins, clips, and rings.
