Rear suspension upgrade for the Traxxas Unlimited Desert Racer

Fit GPM's robust aluminum rear spring dampers to lower internal friction and manage shock pressure, delivering steadier handling during high speed runs and rough sections.

Design Highlights

  • Thickened Coil: Coil thickness is increased from 1.8mm to 2mm to give stronger spring response while still allowing the original spring to be used if preferred.
  • Reinforced Shock Shaft: The shock shaft size jumps from 3.5mm to 5mm to resist bending and improve long term stiffness under load.
  • Sturdy Aluminum Construction: The aluminum shock body keeps weight low while adding strength, and the sealed spring retainer helps prevent oil leakage.

Packing includes

  • Rear Spring Dampers – 2pcs

Compatible Models

  • Traxxas Unlimited Desert Racer

Just received Avery well packed and vey shiny box of GPM parts... all look great... only one negative... and probably on my part... the discs and calipers come in sets of 4... not 4 discs or 4 calipers.. oh well another order to follow... great service th

Will these dampers install on stock UDR rear mounts?

Yes. These dampers are made for the Traxxas Unlimited Desert Racer and fit the original rear mounting points without modification.

Can I reuse my original springs with GPM UDR139R dampers?

Original springs can be used as an option, letting you keep a familiar ride height while benefiting from the thicker coil and stronger shaft.

How much more resistant is the 5mm shaft to bending?

The larger 5mm shaft offers noticeably greater stiffness and bend resistance than the 3.5mm shaft, improving durability under heavy use.
