Namura Technologies Top End Repair Kit Polaris Oversize Bore Engine Piston

The Namura Technologies Top End Repair Kit is an oversize bore piston and top end rebuild kit for Polaris ATV and UTV engines. It is also sold as a top end rebuild kit or piston and gasket kit. It gives you the parts for a top end rebuild in one package, so you can restore compression and engine performance after the cylinder has been bored or honed.

Key Features:

• Oversize piston for rebuilding a cylinder that has been bored or honed oversize
• MOS2 (Teflon/Molybdenum) coated skirts applied by a rolled-on process. This reduces friction, improves heat transfer and helps prevent cold seizures.
• Machined smooth piston crown reflects combustion heat and reduces carbon buildup
• Anodized piston dome and high silicone content for heat resistance and strength
• Complete rebuild components in the manufacturer's kit design: piston, rings, wrist pin, circlips and a top end gasket set. Needle bearings are included where the engine requires them.

Namura aims to deliver a higher performance piston without a higher price. This makes the kit a practical choice for a worn-engine rebuild or routine maintenance on a Polaris powersports machine.
