Race Pan Car Differential Sleeve 4x6x3 Arrowmax AM-931020  [AM-931020]

4x6x3 Sleeve for Differential Precision

The Arrowmax AM-931020 is a compact 4x6x3 bushing intended for RC pan car geardiff and differential assemblies in 1/12, 1/10 and F1 formats. It acts as an internal bearing surface to help control shaft alignment and preserve correct gear mesh without implying any use on road vehicles.

To fit, confirm the housing bore and shaft sizes are compatible with 4x6x3, prepare and clean all mating surfaces, then seat the sleeve so it is flush with the housing. A light smear of lubricant during first runs will help bedding in and reduce initial friction.

When tuning or servicing gear diffs, this sleeve can recover tightness in worn setups and assist in fine adjustment of backlash. Regular inspection is advised and replacement should follow any sign of excessive clearance or deformation.
