Precision Rear Internal Shocks 160mm

A precision machined rear internal shock set designed for the TRAXXAS UNLIMITED DESERT RACER platform, supplied as the rear pair. The assembly replaces stock internals to provide more uniform damping and extended component life under demanding use.

Components are produced from 6061 T6 aluminium with precision sealing to limit oil loss while maintaining low mass. Units arrive filled with a higher viscosity suspension oil to increase damping force and control, and the shaft diameter has been increased from 3.5mm to 5mm to reduce bending under heavy loads.

Installation is a direct replacement for the rear internal assemblies on the stated chassis; use standard mounting hardware and verify shaft alignment during fit-up. For set-up, vary oil viscosity and spring preload to refine rebound and compression for the intended surface and driving style.

Specifications

  • Item: Rear internal shocks (rear), 160mm, 2 pcs
  • Material: 6061 T6 aluminium
  • Model Number: UDR160RX
  • Compatibility: TRAXXAS UNLIMITED DESERT RACER

Engineered as a sealed aluminium upgrade that prioritises consistent damping and increased durability for rear suspension use on the TRAXXAS UNLIMITED DESERT RACER, with straightforward tuning options for performance-oriented hobbyists.

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

What are the key mechanical changes compared to stock?

Key changes include 6061 T6 aluminium bodies with precision seals, higher viscosity filling oil, and an increase of shaft diameter from 3.5mm to 5mm for improved stiffness.

How should I approach tuning with these units?

Begin with a medium weight oil and the stock spring preload, then incrementally increase oil viscosity or preload to reduce bottoming while monitoring rebound speed to avoid packing.

Are there special installation checks?

Confirm shaft alignment and smooth travel through the full suspension arc, ensure seals are seated correctly, and reuse compatible mounting hardware to maintain geometry.
