Product Details

The WSM 010-831-05K is a complete piston kit designed for Polaris 650cc engines, featuring a 0.5mm oversize bore for rebuilding worn cylinders. This comprehensive kit includes the piston, rings, wrist pin, and circlips—everything needed for a proper piston replacement.

Platinum Series Features:

  • Constructed from high-strength hardened aluminum alloy engineered to prevent skirt and ring groove breakage under high-stress conditions
  • Piston walls feature a specialized non-abrasive coating that reduces heat buildup and friction, increasing horsepower output while extending component life
  • Manufactured to exact OEM specifications for precise fitment and reliable performance
  • Oversized 0.5mm design allows for cylinder bore restoration during engine rebuilds

WSM's Platinum Series pistons are ideal for both performance rebuilds and stock replacement applications on Polaris watercraft engines. The advanced coating technology and premium materials ensure long-lasting durability in demanding marine environments.

Had no Problem.

I would have liked better clarification on part ordered and shipping time. Also on the replacement part, filler neck, the vent tube had a slightly larger flare at the end which was nearly impossible to fit in the OEM fuel vent hose.

Ordering was simple, just waiting for arrival
