The Kyosho OTW101-02 Ball Differential Shaft is a straightforward upgrade tailored for the OPTIMA line. This shaft helps balance torque between wheels to reduce wheel spin and improve on-track stability, making it well suited for hobbyists who want consistent handling across mixed surfaces.
Built with precision in mind, the OTW101-02 enhances traction by improving differential action under load. The result is better cornering consistency and reduced understeer or oversteer when powering through bends.
For reliable operation install the OTW101-02 with clean mating parts and inspect bearings before assembly. Apply the recommended lubrication to moving surfaces and check mesh and preload to avoid premature wear.
