Enhance TB-04 Handling with the Tamiya Front One-Way

The Tamiya 54521 Front One-Way Set is an upgrade created for the TB-04 shaft-driven touring chassis. It cancels front wheel braking which produces cleaner turn-in and a more agile feel through bends. Compared to conventional ball differentials the one-way offers stronger acceleration when the driver applies throttle mid corner.

Key Points for Tuners

Removes braking force on the front wheels for sharper steering
Boosts acceleration relative to standard ball diff setups
Includes 2mm pins and O-rings for direct installation into the diff housing
Compatible with TB-04 and TB-04 PRO chassis models

Does the one-way change braking feel overall?

Yes, the front no longer contributes to braking which can make initial braking feel lighter; most tuners adjust driving style or rear settings to compensate.

Is this suitable for race or club use?

The part is well suited to competitive track use where sharper turn-in and improved drive out of corners are desired; regular inspection of O-rings and pins is advised.

What parts are included in the kit?

The kit ships with the one-way assembly plus the required 2mm pins and O-rings so you can install it directly into TB-04 front differential housings.
