Product Details
Highlights
- Piston kit includes forged pistons (unless noted) rings, wrist pins and clips for a complete motor replacement.
- Made in the U. S. A.
These big bore pistons work with the stock 4" stroke flywheels to convert any 1999-'06 HD big twin engine from 88" to 97" displacement with 9.7:1 compression with stock heads. Stock cylinders may be bored to accomodate larger pistons, but we recommend S&S 3.927" bore cylinders which feature high strength alloyed cast iron liners. Pistons are compatible with stock rods with tapered wristpin ends. S&S 3.927" bore pistons are machined to such close tolerances that it is not necessary to measure the piston. Just bore cylinders to nominal diameter +/- 0.0005" for correct clearance. Additionally, the low friction coating on the piston skirt makes taking measurements very difficult. 3.927" +.010" bore.
