S&S Low Compression Piston Set 3-7/16" 8.0:1


The modern alloys used in these pistons, coupled with the advanced skirt profiles, result in low engine noise and long engine life, something that in the past could only be achieved with cast pistons.

  • Made in the USA

Product Note: 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 half point, and may result in clearance problems (check all piston to cylinder head clearances carefully when using early style rods).
