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).
