GPM Racing Aluminium 6061-T6 Front L-Shape Piggy Back (Built-in Piston) Internal Damper 135mm for Traxxas 1/7 Unlimited Desert Racer-85076-4 (UDR135FX/LN)

Front L-shape piggy back damper specifications

This 135mm front L-shape piggy back internal damper uses 6061-T6 aluminium for a robust serviceable body and includes an integrated piston to provide variable damping control for the TRAXXAS UNLIMITED DESERT RACER platform. The design aims to let hobbyists adjust front-end damping without altering primary chassis geometry.

Installation targets the front shock mounting positions and follows standard removal and replacement procedures used on 1/7 scale desert racer assemblies. Damping adjustments are made by changing the top spring retainer and by rotating the red adjustment screw located at the base of the negative pressure oil cylinder, providing a simple method to tune spring/damper response for different track conditions.

The component is supplied as a pair for both front dampers and is intended for RC-only use on the specified compatible TRAXXAS chassis. It retains piggy back oil capacity while delivering durable 6061-T6 aluminium construction and internal piston control for ongoing service and tuning.
