Product Details

Forged Piston Set (106-3964A) by S&S Cycle®. These forged 3-7/8" bore stroker pistons for 1999-'16 HD® big twin are required for the S&S 106" stock bore stroker kit with 4-1/2" stroke flywheels. They are compatible with stock or S&S® Super Stock® cylinder heads. Stock 88" cylinders may be bored to fit these pistons, or S&S has replacement cylinders available. +.010" oversize.

Notes

  • S&S 41/8" pistons are machined to such close tolerances that it is not necessary to measure the piston. Additionally, the low friction coating on the piston skirt makes taking measurements very difficult. Therefore, hone cylinders to nominal diameter +/- 0.0005" for correct clearance.

Features

  • Piston kits include set of pistons, rings, wrist-pins and clips
  • All are flat top piston type, unless noted
  • Made in USA
  • Precise engineering ensures the latest in quality
  • Expertly manufactured from highly reliable materials
  • Rigorous quality control and great functionality

Founded in 1958, S&S Cycle® has been providing high performance motorcycle parts for Harley-Davidson® and other v-twin motorcycles for over 55 years. Starting with a simple offering of light weight pushrod kits, the S&S motorcycle performance product line has grown to include exhaust systems, camshafts, carburetors, fuel injection systems, stroker kits, big bore kits, cylinder heads, service replacement parts and complete motorcycle engines for both vintage and modern v-twins.
