S&S Cycle Forged Piston Kit (80ci.) - .010 Oversize, 8.75:1 High Compression

  • 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)
