Description

A worn or damaged piston directly compromises your TRX350 Rancher's combustion efficiency, throttle response, and overall engine reliability. The Wiseco Piston Kit restores factory performance while delivering the durability needed for sustained riding and potential future upgrades. This is essential maintenance for riders who demand consistent power delivery and longevity from their machine.

Wiseco pistons are precision-engineered to exacting tolerances, ensuring a perfect fit within your engine's bore without requiring any modifications. The 78.50mm standard bore sizing means straightforward installation—no custom work needed. With an 8.8:1 compression ratio, this kit maintains OEM-spec parameters while supporting your engine's thermal and mechanical demands.

Note: This kit does not include gaskets. You'll need to source a complete gasket set separately to ensure a proper seal during installation.
