GPM TRAXXAS UNLIMITED DESERT RACER Rear L-shape Piggy Back Damper Set UDR13960RR/L - RC Spare Part  [UDR13960RR/L]

Aluminum L-shape piggy back rear shocks for Traxxas UDR

This four-piece aluminum rear L-shape piggy back damper set is built for the TRAXXAS UNLIMITED DESERT RACER platform and supplied as two coil-on spring units plus two internal dampers for RC rear suspension use. These parts aim to reduce friction and manage impacts to give the model improved balance across rough terrain.

The bodies are CNC machined from 6061 T6 aluminum with sealed construction to limit oil loss, and use a higher concentration suspension oil for steady damping. Shafts are upsized from 3.5mm to 5mm to increase stiffness, and the coil spring wire is strengthened from 1.8mm to 2.0mm while remaining compatible with original springs when a softer rate is preferred. The L-shape reservoir extends oil travel to smooth response during long stroke movements.

Tuning notes for fitment and setup: verify mid-point distances before mounting, with the spring damper mid-point at 139mm and the internal damper mid-point at 160mm. Check shock tower and mount clearance, begin with stock springs if unsure, then fine-tune oil viscosity and preload to dial in rear-end behaviour for your driving surface.

This UDR13960RR/L damper set is a direct-fit aftermarket upgrade for rear suspension builders who want firmer components and a piggy back reservoir to stabilise damping with standard installation and tuning steps.
