Features & Benefits:-

* 3.937in. Bore.

* 4-3/8in. Stroke.

* Pistons are compatible with stock conrods with tapered wristpin ends.

* S&S bore pistons are machined to such close tolerances that it is not necessary to measure the piston.

* Just bore cylinders to nominal diameter +/- 0.0005in. for correct clearance.

* Additionally, the low friction coating on the piston skirt makes taking measurements very difficult.

* 10.4:1 Compression Ratio with Stock Head.

Tech Tips:-

* Follow Ring End Gap & Piston to Cylinder Clearances as per the supplied Manufacturers Instructions.

* Pull the engine down first & measure the existing bore to determine if oversize pistons are required PRIOR to purchase, we do not take back piston kits. The onus is on the assembling technician to validate the cylinders & required pistons.
