GPM Racing Aluminium Front L-Shape Spring Damper (135mm) - 2pcs Set for Traxxas 1/7 Unlimited Desert Racer-85076-4 (UDR135F/L)

Precision 135mm L-shape Front Damper

The GPM front L-shape spring damper is a CNC-conscious aftermarket replacement intended for TRAXXAS UNLIMITED DESERT RACER style chassis and other vehicles that match the 135mm front dimension. It is designed to control vertical wheel travel, manage frictional losses and dissipate impact energy to maintain chassis balance on uneven terrain.

Key engineering changes versus common stock units include a coil spring wire increase from 1.8mm to 2mm to broaden available spring rates while preserving fitment for the original spring, an enlarged damper shaft dimension raised from 3.5mm to 5mm to improve column stiffness, and an aluminium-machined damper body with a sealed spring retainer to limit oil leakage. The integrated L-shape piggyback reservoir increases oil travel length to stabilise damping response across varied stroke speeds.

Packing includes

• Front Spring Dampers – 2pcs

What hardware is supplied?

Supplied items are two front L-shape spring dampers sold as a 2pcs set suitable for front installation.

How does the increased shaft diameter affect performance?

A 5mm shaft reduces bending and deflection under load, delivering more consistent damper action and improved predictability during tuning.

Are these compatible with original springs?

Yes, the damper retains compatibility with the original spring to allow softer setups, while supporting higher rate springs enabled by the 2mm wire.

What maintenance is recommended?

Regular inspection of seals and shafts, periodic oil refresh and prompt replacement of worn seals will maintain damping consistency and extend service life. Write Product Review Please sign in your account before you can write any review. Sign In Close
