High-quality connecting rod kit engineered for performance and durability. Manufactured from hot-rolled ASTM 4115 steel and case-hardened to 58-62 Rc, this kit features advanced scalloping and vent slots in the big end to minimize bearing race distortion at high RPMs. Double-forged rods enhance grain flow and maintain dimensional consistency, while shot-peening and double-honing deliver superior strength under heavy loads.

The small ends are double-drilled to optimize lubrication and cooling, ensuring reliable operation of wrist pin bearings even under extreme conditions. Silver-coated thrust washers and crank pin bearings provide additional lubricity for enhanced longevity. The kit is sold complete with all components needed for installation.
