Owners of Kyosho MP9 cars can swap in the IF412B Differential Shaft to maintain drivetrain performance. The shafts support steady torque transfer through the diff and help preserve handling consistency.
The Kyosho IF412B Differential Shaft is produced to suit MP9 differential assemblies and fits without bespoke modification. Two shafts are supplied so you can replace both sides during a service interval.
Fitting these shafts is straightforward for anyone familiar with RC strip-down work. Use stable supports, check orientation and alignment, and ensure there is no binding before sealing the diff housing.
