ProX Racing Parts Engine Rebuild Kit - 10.EK5806.A1

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 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 OEM-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.
