Tamiya TB04 Adjustable Aluminium Spring Damper Pair TB4055F/RPBT by GPM  [TB4055F/RPBT]

Adjustable aluminium dampers suited to TB04

The TB4055F/RPBT is an aftermarket front/rear adjustable spring damper designed for the Tamiya TB04 chassis. These units combine aluminium bodies with a plastic ball top and are shipped as one pair to serve as replacements for the stock TB04 shocks.

Designed as a tuning component rather than a complete shock system, it provides click-free height and spring preload adjustment while preserving the TB04 shock mounting points. The plastic ball top gives a stable pivot for the suspension linkage and helps refine ride feel and transient response.

Installation follows the standard TB04 procedure: remove the original dampers, transfer any preferred springs or retainers, install the TB4055F/RPBT dampers into the towers and arms, and refit ball cups and retaining hardware to existing locations. Inspect for consistent travel and smooth shaft action after fitting.
