TAMIYA TB04 Aluminium Threaded-Preload Damper Front and Rear TB4055F/R by GPM  [TB4055F/R]

Precision aluminium adjustable damper for TB04

This aftermarket front and rear damper is specified for the TAMIYA TB04 chassis and carries the part number TB4055F/R. The unit uses a durable aluminium body and a threaded spring collar to permit preload changes without shock removal, offering a compact upgrade for scale suspension tuning and setup.

Installation follows standard TB-04 procedures: remove the stock shocks, install the replacement dampers into the original shock towers and lower mounts, and change pin positions if necessary. No alterations to electronics, motor, or gearbox are required because this part modifies only the suspension.

Operationally the damper provides fine preload adjustability and helps maintain consistent spring seating. Adjust the threaded collar to modify preload and thereby affect ride height and initial spring rate, then verify geometry and wheel alignment. Use preload changes in concert with appropriate shock oil and spring choices for consistent handling results.

Service notes: keep threads free of contaminants, confirm springs remain seated correctly, and inspect mounting pins and retainers for wear. Clean aluminium surfaces with mild solvent and avoid abrasive cleaners that could affect fit or finish. This component is intended strictly for radio control models.
