ProX Piston Kit Oversize Yamaha Blaster

The ProX oversize piston kit is a 2-stroke engine top-end piston kit for rebuilding or re-boring a worn cylinder. It is available in a range of oversize options. Oversize pistons give you more re-bore opportunities, which helps extend the life of the cylinder.

Key Features:

• Oversized piston follows the manufacturer's piston-to-cylinder wall clearances
• Precision machined on CNC equipment
• Made from a low-expansion, low-friction aluminum alloy, the same type of alloy used by major Japanese engine manufacturers
• Cast piston design with a moly-coated skirt
• Kit includes piston, rings, circlips and wrist pin

ProX piston kits are a dependable choice for engine rebuilds and for restoring compression and performance in a worn 2-stroke engine.
