Optimise ULTIMA drive with the Kyosho UMW602B differential

Enthusiasts seeking crisper handling for ULTIMA SC, DB, RB5 or RT5 models will benefit from the Kyosho UMW602B Ball Differential Set. It improves traction delivery and helps the car rotate more predictably through corners.

What the ball differential delivers

Unlike gear differentials, a ball differential allows gradual slip and even torque distribution to both wheels. This reduces sudden breakaway and provides better modulation on mixed surfaces.

The UMW602B is tailored for the ULTIMA SC, DB, RB5 and RT5 ranges and is intended for direct substitution into the respective differential housing. Double-check your chassis variant before ordering to ensure fit.

Maintenance and fitting advice

Assemble on a clean bench and protect components from dirt. Use the appropriate lubricant and inspect the assembly at intervals to prevent premature wear and maintain consistent performance.
