RC builders who maintain Kyosho MP9 cars will find the IF412B Differential Shaft a useful replacement part for preserving drivetrain integrity. It helps the differential transfer torque cleanly and reduces unexpected drivetrain behaviour during running.
The Kyosho IF412B Differential Shaft is tailored for MP9 chassis layouts and installs without alteration. The pair of shafts in the pack allows you to service both sides or carry a spare for quick trackside changes.
Fitting the IF412B shafts is a straightforward task for anyone familiar with RC maintenance. Use a clean workspace, ensure shafts sit true in the diff housing, and recheck gear mesh after installation to avoid premature wear.
