The HOT RODS Connecting Rod Kit (Part Number 8663) offers a high-performance, heavy-duty replacement solution for KTM 450EXC and 450XC-W models. Crafted from certified 8620 AISI steel, these connecting rods provide exceptional strength and durability essential for demanding high-rpm applications. The crankpins are manufactured from hot-rolled ASTM 4115 steel and undergo case hardening to a level of 58-62Rc, ensuring long-lasting wear resistance. The latest caged needle roller bearing designs incorporated into these rods enhance longevity at elevated engine speeds, making them suitable for performance and racing use. The big end features strategically placed side scalloping and vent slots that help minimize bearing race distortion during high rpm operation, contributing to engine stability and reliability. The small ends are double drilled to supply additional lubrication and cooling to the wrist pin bearing, which is particularly beneficial when the piston crown is close to the wrist pin area. These rods are shot-peened to eliminate surface stress risers and ensure smooth blending of the forging’s radiuses, further enhancing durability. Double honing of the bearing surfaces produces an ultra-round finish, providing reliable performance at high engine speeds. This kit is typically sold complete with the rod, crank pin, crank pin bearing, top-end bearing, and silver-coated bronze phosphor thrust washers, offering a comprehensive upgrade for your engine. Made in the USA, the HOT RODS Connecting Rod Kit is compatible with OE crankshafts and hot rods, making it a trusted choice for performance enthusiasts seeking reliable, high-quality replacement components for KTM motorcycles.
