ProX Engine Rebuild Kit

Complete rotating and reciprocating rebuild kit including crankshaft assembly, main bearings and seals, pistons and components, and a complete engine gasket kit. All components were developed through extensive research and development on Pro. X’s in-house engine dyno. Crankshafts come completely assembled using Maxima ® assembly lube and are inspected in-house for proper dimensions and trueness. Connecting rods feature proprietary design done in-house, and are forged, heat-treated, and shot-peened for ultimate tensile strength and reduced stress risers. Connecting rods include graded bearings in the big end to ensure proper clearance, as well as a bronze bushing in the small end, both improving longevity and performance. Pistons are cast from Orig. Equipment-grade alloy and feature MOS2 skirt coating and hard-anodized crown and ring grooves for improved performance and wear resistance through reduced friction and improved heat resistance. Includes Japanese-sourced, Koyo main bearings along with Orig. Equipment quality seals and complete gasket kit to ensure a reliable engine rebuild. More applications covered in fewer part numbers with versatile gasket kits and compression ratios. Available in A/B/C graded bore sizes.
