S&S Cycle® +0.030" Bore Forged High Compression Aluminum 74" Piston Kit, with All Necessary Hardware - Made in U.S.A.

Fits 1941-1984 Harley Models with Big Twin Motors 

Features:

• PISTON KITS

• Replacement pistons available for stock and big-bore applications

• All piston kits come with two pistons, rings, wrist pins, and wrist pin keepers

• Compression ratios listed are approximate and are calculated using the correct length cylinders as specified by S&S

• Require the use of connecting rods with a rod length of 7.440" (standard length OEM #24281-74A connecting rods); use of earlier connecting rods with a 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 the early style rods)
