Namura Technologies PWC Piston Kit - Oversize

Namura Technologies PWC oversize piston kits are replacement piston kits for personal watercraft (jet ski) two-stroke engines. They suit rebuilds where the cylinder has worn or been honed or bored. An oversize piston kit restores cylinder sealing and compression. It costs far less than replacing the cylinder.

Key Features:

• Multiple oversize options: Namura offers oversizes in small increments, so you can match the piston to your cylinder's bore after machining.
• Cast piston construction: The pistons are cast with a high silicon content for added strength and wear resistance.
• Coated skirts: Molybdenum/Teflon-coated piston skirts reduce friction and wear and help extend service life.
• Machined smooth piston heads: The smooth crown reflects combustion heat and reduces carbon buildup.
• Complete kit hardware: Kits are built around a piston, ring set, wrist pin and clips, so the parts are matched for installation.

Namura kits are made to meet or exceed original equipment fit and function. They are a dependable choice for a PWC top-end rebuild or engine refresh. Choose the correct bore and oversize for your engine from the available options.
