Description
Hot Rods Heavy-Duty Connecting Rod Kit - 8684 is a high-quality replacement designed for Kawasaki KX450F models. Manufactured from hot-rolled ASTM 4115 steel and case-hardened to 58-62 Rc, this kit delivers superior strength and reliability under heavy loads. The advanced design minimizes high-rpm bearing race distortion, and the small end is double-drilled to provide additional lubrication and cooling for the wrist pin bearing.
The rods are double-forged for improved grain flow, shot-peened, and double-honed for enhanced durability. Each kit includes a rod, crank pin, crank pin bearing, top-end bearing, and thrust washers.
