This kit includes two piston kits, with each kit containing pistons, rings, circlips, and wrist pins. Key features of these pistons include:
Enhanced combustion heat transfer: Designed to provide the best possible path for combustion chamber heat to transfer to the cylinder walls.
Manufactured to OEM specifications: All components (pistons, rings, pins, circlips) are made to OEM standards, ensuring easy interchangeability with original parts.
Piston weight: Compatible with the original piston weight for a seamless fit.
High-performance aluminum alloy: The pistons are made from an aluminum alloy that maintains its high tensile strength up to 700 F (50% higher than conventional cast pistons). This high temperature resistance improves fatigue strength and impact toughness, ensuring longer-lasting performance.
Standard bore size: 85.00mm.
Compatible with the following Polaris models:
