Hot Rods Connecting Rod Kit Fits KX125 88-91/KDX200 89-05/KDX220 97-05

Description

The Hot Rods Connecting Rod Kits are heavy-duty OE replacement parts designed for high performance and longevity. Constructed from certified 8620 AISI steel, these rods offer superior strength and durability. The kits feature crankpins made from hot-rolled ASTM 4115 steel, case-hardened to 58-62Rc, and utilize advanced caged needle roller bearing designs for high RPM endurance. The big end of the rod is uniquely designed with strategically placed side scalloping and vent slots to minimize bearing race distortion at high RPMs. The small ends are double drilled to enhance lubrication and cooling of the wrist pin bearing, crucial when the piston crown is near the wrist pin bearing. The rods are shot-peened to eliminate surface stress risers, providing a smooth blend of the rod forging’s radiuses. Double honing ensures an ultra-round bearing surface for reliable performance at high RPMs. Each rod assembly includes a connecting rod, crank pin, crank pin bearing, top-end bearing, and silver-coated bronze phosphor thrust washers. These kits are compatible with both Hot Rods and OE crankshafts, making them a versatile choice for various applications.
