The Kyosho UM124 tensionner spring helps maintain even tension across drive components, which reduces wear and keeps power transfer consistent. It is a useful replacement part during servicing and repairs.
Suitable for a range of Kyosho-compatible chassis and similar mounting patterns, the UM124 is practical for both onroad and offroad models. Use it when restoring original performance or fine tuning drivetrain feel.
Fitting the Kyosho UM124 is simple when the drive assembly is exposed. Replace the worn spring, verify correct seating, and test the drivetrain at low speed before returning to regular running to ensure tension is correct.
