Kyosho UM610 Diff Bevel Gear Set

The Kyosho UM610 Diff Bevel Gear Set is the complete genuine bevel gear set for the sealed gear differential used on Kyosho's 1/10 off-road platforms. These steel bevel gears form the heart of the diff, transferring power to both rear wheels while letting them rotate at different speeds through corners. Compared with a ball differential, the gear diff design is stronger and more durable, holds its action longer between services, and handles modern brushless power without the constant rebuilds ball diffs demand.

This set installs as a direct replacement for the internals of the Ultima gear differential, with fitment covering the Ultima SC, SC6, RT6, DB, RB6, and RB6.6. It is also the gear set used when converting an RB5 or RB6 ball diff to a gear diff alongside the matching diff gear set. If your diff has developed gritty or notchy action from worn gears, this set brings it back to smooth, quiet operation.
