Tamiya 54329 DB01 Gear Differential Unit OP-1329 Replacement - Rugged Gear Diff  [54329]

Improve DB01 handling with the Tamiya gear differential unit

The Tamiya 54329 DB01 Gear Differential Unit replaces the stock ball diff in DB01, TRF511 and TRF501 buggies, offering a tougher, more predictable drive feel. It is aimed at hobbyists who want simpler maintenance and consistent performance across rough ground.

Set the diff action with different oils

This sealed gear differential can be filled with a range of viscosity oils to adjust how the car transfers power during cornering. Heavier oils reduce internal rotation and increase traction, while lighter oils let the diff work faster for nimble handling.

Built for durability with practical parts

Compared to ball differentials, gear units typically need less frequent attention. This Tamiya unit contains a 37T pulley and 12T plus 20T bevel gears, and it includes the TA06 Cross Shaft to boost strength for regular running sessions.
