S&S Piston Kit - Low Compression - 74" Stock Motor - Standard

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

Fits Harley-Davidson Touring (1958-1980), FX Big Twin (1971-1980) and Vintage (1941-1980) models. Check the fitment chart below to confirm your exact year and model.

• For 74" stock big twin motors
• Forged pistons for superior strength
• Piston kits include set of pistons, rings, wristpins, and clips
• Wrist pin deck height 1.436"
• Made in the U.S.A.
• Requires the use of connecting rods with a rod length of 7.440"(standard length OEM #24281-74A); 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).
