Tamiya TB04 Front and Rear Adjustable Aluminium Spring Damper TB4055F/RPBT by GPM  [TB4055F/RPBT]

Aluminium adjustable dampers for TB04 setups

The TB4055F/RPBT pair is an aftermarket front and rear adjustable spring damper made to fit the Tamiya TB04 chassis. The units pair aluminium damper bodies with a plastic ball top and are supplied as one pair to replace or upgrade the stock TB04 dampers.

As a tuning component it provides click-free height and spring preload adjustment while maintaining the original TB04 shock mounting geometry. The plastic ball top gives a reliable linkage point and helps tune transient response and ride character without changing shock locations.

Fitting is straightforward on TB04 shock positions: remove the factory dampers, move springs and retainers across if you prefer, fit the TB4055F/RPBT units into the shock towers and lower arms, then secure ball cups and hardware to the original attachment points. After installation check for smooth shaft travel and full suspension droop and compression.
