S&S Cycle 99-06 BT 3.927in Standard Bore 97in Big Bore Forged Piston Set
SKU: S0GE 106-3688
Description
Part #: 106-3688
These big bore pistons work with the stock 4" stroke flywheels to convert any 1999-'06 HD (R) 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 (R) 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" standard bore.
