Rebuild your bottom end with confidence using this PROX Connecting Rod Kit for 450cc 4-stroke engines. Built from forged steel, it’s designed to handle the loads of hard riding and help restore smooth, reliable engine operation. Because it arrives as a complete kit, you avoid missing parts and reduce time spent sourcing bearings and hardware separately.
If your engine shows signs of wear (play/noise from the crank area, metal in oil, or you’re already doing a full rebuild), a new connecting rod assembly is a critical step toward long-term reliability and consistent performance.
