Upgrade your KTM engine with the HOT RODS Connecting Rod Kit, designed specifically for models including 125EXC, 125SX, 144SX, 150SX, and 150XC. Crafted from certified 8620 AISI steel, these heavy-duty OE replacement connecting rods deliver exceptional strength and durability for high-performance riding. The crankpins are manufactured from hot-rolled ASTM 4115 steel and case hardened to a level of 58-62Rc, ensuring resilience under demanding conditions. Featuring advanced caged needle roller bearing designs, these rods provide high rpm longevity and reliable operation at peak speeds. The big end of the rod is uniquely designed with strategically placed side scalloping and vent slots to minimize bearing race distortion during high rpm operation, maintaining optimal alignment and performance. The small ends are double drilled to supply extra lubrication and cooling to the wrist pin bearing, which is crucial when the piston crown is close to the wrist pin, reducing wear and extending engine life. Shot-peened to eliminate surface stress risers and smoothly blend the radiuses of the forging, these rods are engineered for strength and reliability. Double honing on the bearing surface ensures an ultra-round fit, critical for high rpm stability and durability. Most components are 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. Proudly made in the USA, these connecting rods are compatible with hot rods and OE crankshafts, making them a trusted choice for performance enthusiasts seeking long-lasting, reliable engine components.
