Upgrade your small engine with the HOT RODS Connecting Rod Kit designed specifically for Gas Gas MC50, Husqvarna TC50, and KTM 50SX models. Crafted from certified 8620 AISI steel, these heavy-duty connecting rods provide exceptional strength and durability essential for high-performance applications. The components feature precision manufacturing, with crankpins made from hot-rolled ASTM 4115 steel and case hardened to 58-62Rc, ensuring resistance to wear and fatigue during intense operation. The innovative caged needle roller bearing design enhances high RPM longevity, delivering reliable performance under demanding conditions. The big end has been uniquely engineered with strategically placed side scalloping and vent slots to reduce bearing race distortion at elevated speeds, maintaining optimal alignment and reliability. The small ends are double drilled to facilitate additional lubrication and cooling for the wrist pin bearing, which is particularly beneficial when the piston crown operates near the wrist pin area. These rods are shot-peened to eliminate surface stress risers and to smooth the radii of the forging, contributing to overall strength and fatigue resistance. Double honing ensures an ultra-round bearing surface, supporting smooth operation at high rpm and reducing wear over time. Most complete rod assemblies include 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, these connecting rods are compatible with Hot Rods and OEM crankshafts, making them an ideal choice for rebuilds and performance enhancements in small displacement motorcycles.
