If you want crisper steering feedback, the Tamiya 54897 Ball Differential Set II OP-1897 brings a cleaner power transition than standard bevel diffs. It helps deliver smoother torque to the wheels, which riders find useful for both practice laps and casual bashing.
The kit is compatible with multiple Tamiya buggies such as the Buggy Champ (2009), Sand Scorcher (2010), and Fighting Buggy (2014). Included are a 1150 ball bearing, eight 3mm differential balls, plus 4mm and 5mm screws to make installation straightforward.
This ball differential stands out for how easily it can be adjusted while still mounted. That means quicker setup changes between runs and less time on the bench when you want to tweak handling.
