Tamiya DT03 Rear 90mm Aluminium Adjustable Damper by GPM DT3090R/PBT  [DT3090R/PBT]

Rear damper for DT03 chassis

This aluminium rear damper set is an aftermarket replacement produced for Tamiya DT03 users, sold under GPM model DT3090R/PBT. The unit uses an aluminium damper body combined with a plastic ball top, and the 90mm length matches the rear damper role stated in the product name. The component is provided as a 1pr set for rear suspension on the DT03 platform.

In practice this part is intended to replace standard rear dampers on DT03-spec chassis without requiring modification to the chassis mounting points. The adjustable plastic ball top allows for quick changes to ride height and link geometry where applicable, supporting incremental tuning during setup sessions.

When integrating the damper, check existing mounting hardware and shock shafts for compatibility, and retain original end-links and screws unless the kit specifies replacements. The aluminium body offers consistent damping housing rigidity while the plastic ball top reduces wear at the linkage interface.

For DT03 racers and tuners seeking a straightforward aluminium-bodied rear damper with a plastic ball top, this GPM unit provides a direct aftermarket option that focuses on suspension tunability and consistent damper housing stiffness.
