Restore Compression and Eliminate Oil Consumption

The Core of Your Engine’s Power

The New Cylinder and Molly upgraded piston are the core components of your engine’s power-generating process. Specifically, the cylinder provides the precision-machined bore in which the piston moves up and down. This new piston comes with rings, a wrist pin, and circlips, and these components work together to seal the combustion chamber. They also efficiently transmit the force of combustion to the crankshaft. Worn cylinder bores and piston rings lead to a loss of critical compression, which directly translates to reduced horsepower and torque. Replacing these components with new, factory-spec parts ensures a tight seal and maximum combustion efficiency. This fully restores your engine’s power output.

Molly Upgraded Piston for Enhanced Durability

The included Molly upgraded piston is a key feature of this kit, designed to provide superior performance and longevity. The piston is coated with Molybdenum Disulfide (“Molly”) on the skirt. This special coating significantly reduces friction and heat. Thus, it minimizes wear on the piston and cylinder walls, particularly during the initial break-in period. This low-friction surface allows for a smoother, more efficient operation. It also provides an extra layer of protection against scuffing and premature wear. This advanced component ensures your top-end rebuild not only meets but exceeds original factory standards for durability.

Complete Sealing for Longevity

For any top-end engine overhaul, installing a complete and new gasket set is absolutely essential. Gaskets are designed to compress and form a perfect seal upon initial installation. Reusing old, fatigued gaskets dramatically increases the risk of leaks, compression loss, and potential fluid cross-contamination. The included top-end gasket set provides all the necessary seals for the cylinder head, valve cover, and other crucial top-end components. By replacing all these critical parts, this kit ensures a factory-tight seal and the long-term reliability you expect from your machine. Therefore, you protect your engine from future issues and extend its lifespan.

Precision-Engineered for Factory-Level Performance

Every component in this REV6 Complete Top End Rebuild Kit offers unparalleled precision for your Polaris 570. Specifically, the new cylinder, Molly upgraded piston, and top end gasket set are OEM Quality & Performance. They meet or exceed original equipment manufacturer specifications. This ensures a perfect fit and reliable operation. Furthermore, these components are Built to Last. High-quality, durable, and high-temperature-resistant materials make them. Thus, they withstand the continuous exposure to extreme combustion heat, high pressures, and constant friction within the engine. Ultimately, you achieve superior durability and long-term reliability. Your engine will maintain optimal compression and power. Moreover, it will perform flawlessly for years to come. Trust REV6 for components that keep your machine performing at its best.
