Kyosho UM613 Diff Bevel Shaft (2)

Kyosho UM613 is a genuine pair of differential bevel shafts for the sealed gear diff on Kyosho's 1/10 off-road vehicles. These are the steel cross pins that mount the internal bevel gears inside the differential case, holding the spider gears in position while they rotate under load. The pins take constant stress every time the diff works through a corner or absorbs a landing, and over time they can wear, groove, or bend, which introduces play into the diff and accelerates gear wear.

Installing fresh cross pins during a diff rebuild is cheap insurance that keeps the gear mesh true and the diff action smooth. These are direct factory replacements for the pins in the Ultima gear differential, with fitment covering the Ultima SC, RT6, DB, and RB6, and the same pins service other Kyosho diffs built on this design, including V-One R4 and Lazer ZX7 applications. Package includes two bevel shafts, a complete set for one differential.
