High-quality replacement connecting rod kit designed for durability and performance. Manufactured from hot-rolled ASTM 4115 steel and case-hardened to 58-62 Rc, this kit provides exceptional strength and longevity. Its advanced design includes strategically placed side scalloping and vent slots to minimize high RPM bearing race distortion. Double-forged rods improve grain flow and maintain dimensional consistency, while shot-peening and double-honing enhance strength under heavy loads. The small ends are double-drilled for additional lubrication and cooling, critical for wrist pin bearings under extreme conditions. Thrust washers and crank pin bearings are silver-coated for added lubricity. Sold as a complete kit with rod, crank pin, crank pin bearing, top-end bearing, and thrust washers. Features include manufacturing from hot-rolled ASTM 4115 steel and case-hardening to 58-62 Rc, side scalloping and vent slots to reduce high RPM bearing race distortion, double-forged rods to improve grain flow and dimensional consistency, shot-peening and double-honing for superior strength under heavy loads, double-drilled small ends to enhance lubrication and cooling for wrist pin bearings, and silver-coated thrust washers and crank pin bearings for increased lubricity. The complete kit includes the rod, crank pin, crank pin bearing, top-end bearing, and thrust washers.

FULL DESCRIPTION
Hot Rods Connecting Rod Kit for KTM 450-525
Upgrade your motorcycle's engine with this high-performance replacement connecting rod kit from Hot Rods. Engineered for exceptional durability and reliability, this kit is designed to withstand the rigors of demanding riding conditions.
Crafted from premium hot-rolled ASTM 4115 steel, each rod is case-hardened to a hardness of 58-62 Rc, ensuring superior strength and resistance to wear. The innovative design features strategically placed side scalloping and vent slots to minimize distortion of the bearing race at high RPMs, contributing to a longer lifespan for critical engine components.
Further enhancing its performance and durability, the connecting rods are double-forged to improve grain flow and maintain precise dimensional consistency. Shot-peening and double-honing processes are employed to increase strength under heavy loads. The small ends of the rods are double-drilled to provide enhanced lubrication and cooling for the wrist pin bearings, which is essential under extreme operating conditions. To further boost lubricity and reduce friction, both the thrust washers and the crank pin bearings are silver-coated.
This comprehensive kit includes everything needed for a complete installation: the connecting rod, crank pin, crank pin bearing, top-end bearing, and thrust washers.
