UDR139R/L 139mm Rear L-shape Aluminium Damper Upgrade UDR139R/L by GPM  [UDR139R/L]

139mm Rear L-shape Aluminium Damper Technical Overview

This rear L-shape spring damper set is engineered for the TRAXXAS UNLIMITED DESERT RACER as a performance-focused aftermarket component. The matched pair reduces internal friction and improves impact absorption to keep vehicle balance across extended off-road runs.

Engineering notes: spring wire thickness is increased to 2.0mm to provide a firmer spring characteristic while retaining compatibility with original springs for alternate tuning. The damper shaft diameter is enlarged to 5.0mm to resist deformation under high loads. The aluminium damper cylinder and sealed spring retainer lower leakage risk, and the L-shape piggy-back reservoir increases oil capacity to stabilise damping over long strokes.

Service and installation: this item replaces rear shocks and requires standard disassembly of the rear shock mounts. Use common shock tools such as hex drivers. The product is intended for hobbyists and tuners focusing on suspension setup, handling and durability improvements.

For precise rear travel control and improved oil management under demanding use, this aluminium L-shape damper set provides a durable upgrade path for the TRAXXAS Unlimited Desert Racer platform.
