Wiseco Piston Kit Yamaha Phazer 480 1984-1998 72.50mm SK1036

When you're rebuilding a 1984-1998 Yamaha Phazer 480, settling for OEM components means leaving performance on the table. Wiseco's SK1036 piston kit delivers the strength and thermal stability that 2-stroke engines demand, especially if you're pushing higher RPMs or running your sled hard through a full season. This complete top-end solution eliminates the guesswork—everything you need for a proper rebuild is included, so you can focus on getting back out there.

The high-silicone bar stock construction resists the thermal cycling that typically causes piston wear and ring blow-by. Wiseco's engineered ring tolerances minimize expansion under load, which means consistent compression and reliable power delivery across your operating range. Since this is a complete kit, you're getting matched components designed to work together—mixing brands defeats that precision engineering.
