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. Fit Big Twins from 1936 thru 1999 with stock or overlength 35/8" Big Bore cylinders, and strokes from 331/32" (stock 74") to 43/4" as well as 45/8" stroke S&S Sidewinder® kits. Each piston includes rings, wrist pin and wrist pin keepers. Replacement ring sets are sold each (one set for one piston).
