Wiseco 2345M07300 Pro-Lite Forged Piston Kit Bore - 2-Stroke 73.00mm

The Wiseco 2345M07300 Pro-Lite Piston Kit is a complete 2-stroke forged piston kit featuring a 73.00mm bore diameter, designed for Polaris Fuji-engine snowmobiles. Built with Wiseco's proven Pro-Lite forged piston technology, this kit delivers superior performance and durability over stock OEM pistons for both trail and racing applications.

Kit Includes:

• One forged Pro-Lite piston (73.00mm bore)
• Piston ring(s)
• Wrist pin
• Circlips

Key Features:

• Aerospace-grade forged aluminum alloy — high-silicon, low-expansion construction delivers superior strength-to-weight ratio, improved heat transfer, and extended service life compared to cast pistons
• ArmorGlide skirt coating — reduces friction and provides scuff resistance for long-lasting performance
• CNC-machined precision — diamond-turned finish from computer-controlled turning centers ensures tight tolerances and consistent sizing
• Horizontal slot-pin oiling — reduces friction and provides a pressure seal groove for maximum ring seal
• Race-proven design — built from designs trusted by top race teams across Supercross, Motocross, GNCC, and snowmobile racing
• Forged and manufactured in the USA — Wiseco forges all pistons in-house using proprietary forge tooling
• Fits cast iron bore cylinders — compatible with standard cast iron lined cylinders; does not fit Widetrak models

Wiseco's Pro-Lite line is engineered to outperform OEM pistons with tighter tolerances, greater strength, and more hours of peak performance between rebuilds. Note: Oversize pistons require cylinder sleeving. Always measure your cylinder bore before ordering to confirm proper fitment.
