Connecting Rod Kit

Restore strength and reliability to your 2-stroke engine with the Hot Rods Connecting Rod Kit. This is a heavy-duty OE replacement designed for demanding riding and high-RPM operation, making it an excellent choice for bottom-end rebuilds on 250/300cc 2-cycle engines. Precision manufacturing, advanced bearing design and smart oiling features help reduce wear and extend service life.

If your engine has excessive play, knocking, or you’re planning a full rebuild, this kit provides the critical components needed to refresh the crank/rod assembly with confidence—while remaining compatible with Hot Rods and OEM crankshafts.

Key features:
