- For 80" stock big twin motors
- Forged pistons for superior strength
- Piston kits include set of pistons, rings, wristpins, and clips
- Wrist pin deck height 1.270"
- 9:0:1 compression ratio
- 4.25" stroke length
- +0.020" bore oversize
- Made in the U.S.A
- Require the use of connecting rods with a rod length of 7.440"(standard length connecting rods); use of earlier connecting rod with rod length of 7.470" will result in a slight increase in the compression ratio of about one-halfpoint, and may also result in clearance problems (check all piston to cylinder head clearances carefully when using early style rods)
