The PROX Engine Rebuild Kit Pol (Part Number 10.EK5806.A1) offers a comprehensive solution for restoring motorcycle engines to optimal performance. This complete kit includes a crankshaft assembly, main bearings, seals, pistons, and a full gasket set, providing all necessary components for a thorough rebuild. Each component has been developed through extensive testing on PROX*s in-house engine dyno, ensuring durability and precise fitment. The crankshaft is fully assembled with Maxima? assembly lube and inspected for proper dimensions and true alignment, guaranteeing reliability and smooth operation during engine assembly.
Connecting rods in the kit feature a proprietary design, forged, heat-treated, and shot-peened to maximize tensile strength and reduce stress risers. They include graded bearings in the big end for optimal clearance and a bronze bushing in the small end, which enhances longevity and performance. Pistons are cast from OEM-grade alloy, with MOS2 skirt coating and hard-anodized crown and ring grooves to reduce friction, improve heat resistance, and extend service life. The kit also includes Japanese-sourced Koyo main bearings along with OEM-quality seals and gaskets, ensuring a high-quality rebuild compatible with a variety of applications.
Designed for versatility, the PROX Engine Rebuild Kit Pol covers more applications with fewer part numbers, accommodating different bore sizes and compression ratios.
