We offer three separate grades of replacement piston kits for your snowmobile. We carry the standard OEM style, the tried and proven T-Moly Series, and the Space-Age Aluminum Alloy HYPERDRYVE™. Since we provide these three grades of quality parts, many of the top crank building shops rely on SP1 crankshaft webs and rod kits.

Features:

• Includes: aluminum spacer plate, gaskets, longer bolts and dowel alignment pins
• Required SPI pistons with longer skirts must be ordered separately
