TRAXXAS UNLIMITED DESERT RACER 139mm Rear L-shape Damper Set UDR139R/L by GPM  [UDR139R/L]

139mm Rear L-shape Aluminium Damper Upgrade

This rear L-shape spring damper set serves as an aftermarket upgrade for the TRAXXAS UNLIMITED DESERT RACER to refine rear suspension performance. The matched dampers reduce internal drag and help the model remain composed over corrugated and rough terrain.

Design changes relative to stock units focus on robust performance and predictable oil flow: coil spring wire is increased to 2.0mm for a firmer spring characteristic while still allowing the original springs for a softer tune, and the damper shaft diameter is enlarged to 5.0mm to better resist bending under heavy duty use. The aluminium cylinder and sealed spring retainer reduce leakage risk, and the L-shape piggy-back reservoir increases oil capacity to smooth damping during extended travel.

Fitting notes: this is a rear shock replacement requiring removal of the factory rear shocks; basic shock tools such as hex drivers are used. It is aimed at hobbyists tuning for handling or endurance rather than visual changes.

For controlled rear travel and steadier oil circulation, this aluminium L-shape damper set is a direct performance upgrade for TRAXXAS Unlimited Desert Racer owners seeking firmer springs and a stronger shaft.
