FORGED LOW COMPRESSION PISTONS, FOR 80in. STOCK MOTORS WITH 31/2in. BORE AND 41/4in. STROKE (8:1 C.R.).

Replacement pistons available for stock 74in., 80in. and 35/8in. big-bore applications. All pistons 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. Requires the use of connecting rods with a rod length of 7.440in.(standard length OEM #24281-74A connecting rods); use of earlier connecting rods with a rod length of 7.470in. (OEM #24281-41A) will result in a slight increase in the compression ratio of about 1/2 point, and may also result in clearance problems (check all piston to cylinder head clearances carefully when using the early style rods).
