Description
Factory pistons wear out—especially in high-performance applications where temperatures and combustion pressures demand more. The Wiseco SK1312 piston kit delivers OEM-quality replacements engineered specifically for your 1998-1999 Ski-Doo MXZ 670 and Summit 700 X, restoring lost compression and ring seal while offering the durability needed for aggressive riding and racing. This complete kit arrives ready to install, eliminating the guesswork of sourcing compatible components separately.
Wiseco's high-silicone forged aluminum construction minimizes thermal expansion, meaning tighter tolerances throughout the engine's operating range and reduced blowby. Whether you're rebuilding after a top-end failure or preemptively upgrading before the season, this kit ensures your engine performs at spec without compromise.
