Description for S&S Cycle Replacement Piston Kit 

S&S Cycle Replacement Piston Kit

Fitment Note: Fits S&S 100" and 107" motors with 4" bore.

• S&S pistons are designed with maximum piston/engine life and performance in mind

• Features include offset wrist pin to reduce piston slap and noise

• Piston-to-piston clearance at the bottom of the stroke is concentrated in the rear piston so a longer piston skirt can be maintained on the most critical area - the rear of both pistons

• Forged pistons for 1936-99 Big Twins with stock, longer 3-5/8″ big bore cylinders, strokes from 3-31/32″ (stock 74″) to 4-3/4″ and 4-5/8″ stroke S&S Sidewinders
