S&S Piston Kit - Low Compression - 80" Stock Motor - +.020 for Harley-Davidson

The S&S Piston Kit gives you a precise, durable fit for a strong, healthy top end.

Fits Harley-Davidson models from 1978-1984. Check the fitment chart below to confirm your exact year and model.

• 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"
• Made in the U.S.A.
• Requires the use of connecting rods with a rod length of 7.440"(standard length OEM #24281-74A connecting rods); use of earlier connecting rod with rod length of 7.470" (OEM # 24281-41A) 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).
