TRAXXAS UNLIMITED DESERT RACER 1/7 Front L-shape Piggy Back 135mm Adjustable Spring Dampers by GPM UDR135F/LN  [UDR135F/LN]

Front piggy back adjustable dampers

This is an RC-scale front L-shape piggy back spring damper set designed for the TRAXXAS 1/7 Unlimited Desert Racer platform. Constructed from 6061-T6 aluminum, the pair includes built-in piston springs and a 135mm nominal shock length intended for tuning front-end compliance and impact absorption on the model.

Functionally the units reduce friction and absorb pressure at the front damper area to help the vehicle maintain balance during dynamic runs. The dampers are adjustable: spring preload is set via the top spring retainer while damping adjustment is made using the red screw located at the bottom of the negative pressure oil cylinder, allowing straightforward tuning of spring and damping rates without modifying other chassis components.

Installation targets the front damper area of the chassis and follows standard shock mounting points for the Unlimited Desert Racer; the set is supplied as a matched pair for left and right sides to keep front-end geometry symmetric during setup.

For hobbyists focusing on predictable front suspension behaviour on the 1/7 TRAXXAS Unlimited Desert Racer, this aluminum piggy back damper set offers an adjustable, serviceable option to tune spring preload and damping on the RC model without altering chassis layout.
