Tamiya 54521 One-Way Fitment for TB-04 Touring Cars

This Tamiya 54521 Front One-Way Set is a specific upgrade for the TB-04 shaft-drive touring car chassis. By removing the front wheels braking action the kit enhances steering precision and makes corner exits stronger. It provides quicker acceleration compared with standard ball differentials while keeping the rear handling unchanged.

Notable Points About the Tamiya One-Way

Removes braking effect on the front axle to tighten cornering
Gives improved acceleration versus ball differential setups
Includes 2mm pins and O-rings for a direct swap into the diff
Designed for TB-04 and TB-04 PRO chassis variants

How much setup change is needed after fitting?

Most drivers only need minor trim to roll center or toe settings; the core change is the removal of front braking which alters turn-in feel more than overall balance.

Will tyre wear increase with this part?

Tyre wear pattern may change slightly due to sharper turn-in and earlier acceleration, but normal tyre management and rotation will keep life reasonable.

Can I revert to a ball differential later?

Yes, the one-way can be removed and a ball differential refitted if you want to return to the original braking behaviour; keep original parts safe for conversion.
