Precision tune kit - Tamiya 54897 Buggy Champ Ball Differential Set II OP-1897 for classic buggies  [54897]

Fine tuning with the Tamiya 54897 Ball Differential Set II

For hobbyists seeking to refine their Tamiya buggy's handling, the Tamiya 54897 Ball Differential Set II OP-1897 offers a practical upgrade over conventional bevel-gear differentials. This kit improves power delivery and wheel response, helping owners achieve more predictable traction on varied surfaces.

Model fit and included parts

This ball differential set fits several well known Tamiya buggy platforms, including the Buggy Champ (2009), Sand Scorcher (2010), and Fighting Buggy (2014). The package contains a 1150 ball bearing, eight 3mm differential balls, and both 4mm and 5mm screws, so you get the core parts needed for installation.

Adjust on the car for quick setup

A key benefit of this differential is the simple adjustment process. You can dial in preload and feel while the diff remains in the gearbox, which is convenient for trackside tweaks and quick test laps.
