Revitalize your small-bore two-stroke with the ProX Connecting Rod Kit (Part No. 19-9029 / 03.6220). Manufactured in Japan from ultra-tough, double-forged alloy steels, this kit is engineered to meet or exceed strict OEM specifications, providing dependable durability for high-RPM racing and aggressive trail riding.
Each rod is shot-peened and barrel-finished to completely eliminate surface micro-imperfections, relieve residual stress, and optimize structural grain flow for maximum fatigue resistance. Strategically placed lubrication slots ensure optimal oil feed and cooling to the big-end bearing, keeping your rotating assembly reliable under hard acceleration.

TSO Tip
When rebuilding your 125 or 150 bottom end, always verify that your crankshaft total indicated runout (TIR) measures under 0.03mm on V-blocks before dropping it back into the cases. Generously pre-lubricate the lower rod bearing with clean two-stroke premix oil during assembly to protect the moving parts the split-second the engine fires.
