Kyosho Lzr/MZ/RB Diff Balls 3/32 RC Differential Ball - UM120

The Kyosho KYOUM120 differential balls are 3/32 inch replacement diff balls designed for the Kyosho Lazer ZX, Mini-Z, and RB series RC cars. Differential balls are precision wear components that sit inside the differential assembly, and replacing them when worn restores smooth, consistent power transfer between the wheels. Keeping the diff in good condition has a direct effect on how predictably the car handles, particularly through corners, so having a set of these on hand is straightforward maintenance for any Kyosho owner.
