TAMIYA TB04 Front and Rear Adjustable Aluminium Spring Damper TB4055F/R by GPM  [TB4055F/R]

Adjustable aluminium shock unit for TB04

This aftermarket front and rear spring damper is intended for the TAMIYA TB04 chassis and is listed as TB4055F/R. The design uses an aluminium body and a threaded spring collar so you can alter preload without removing the shock, offering a compact option for scale suspension tuning.

Installation follows familiar TB-04 routines: remove the stock shock, position the new damper in the original shock towers and lower mounts, and change pin orientation if required. No modifications to electronics, motor, or gearbox are needed since this part is for scale RC suspension only.

The damper enables fine preload adjustment and improved spring seating consistency. Use the threaded collar to increase or decrease preload to change ride height and the initial spring rate, then recheck suspension geometry and wheel alignment on both axles. Combine these adjustments with appropriate shock oil and springs for consistent handling results.

Maintenance advice: keep threads clear of dirt, check that springs remain seated, and inspect mount pins and retainers regularly for signs of wear. Clean aluminium parts with mild solvent and avoid abrasive cleaners that could affect fit or finish. This product is for model vehicles and not suitable for road vehicles.
