Fortify your high-revving small-bore engine with the ProX Connecting Rod Kit (Part No. 03.6226). Manufactured from premium, double-forged Japanese steel alloys, this kit is engineered to conquer the brutal thermal and mechanical loads seen in modern two-stroke racing.
Each rod is shot-peened and barrel-finished to completely eliminate surface micro-risks and blend forging lines, optimizing structural grain flow for ultimate fatigue resistance. Strategic lubrication channels feed maximum oil volume directly to the big-end bearing, guaranteeing consistent durability under aggressive throttle.

TSO Tip
When rebuilding these modern Austrian powerplants, make sure to check your flywheel-side main bearing alignment and verify total crankshaft runout on V-blocks is well under 0.03mm before dropping it back into the cases. Always pre-lubricate the lower rod bearing with clean two-stroke premix oil to ensure it's protected the split-second the engine fires.
