TRAXXAS TRX4 Scale Crawler Adjustable Aluminium Dampers TRX4090 by GPM  [TRX4090]

Robust aluminium shock dampers for TRX4

This front and rear adjustable spring damper set is crafted for the TRAXXAS TRX4 Trail Crawler as an aftermarket suspension option. It targets lower internal friction and improved balance during slow technical climbs and scale trail driving.

The design ups key dimensions: spring outer diameter is 17mm (from 16mm), shock cylinder diameter 12.8mm (from 11mm), spring coil wire 1.2mm (from 1.1mm), and shaft diameter 3.2mm (from 3mm). Those increments help the assembly resist flex and keep damping more consistent under load.

Supplied as an 8pcs front and rear kit, the package includes stainless steel round head screws for secure fitment. The dampers allow preload adjustment and can be tuned with different springs and oils to match driver preference and trail surfaces.

Use these dampers to firm up the TRX4's low-speed response and maintain a predictable feel on tight trail lines; adjust preload and oil to tailor balance and roll behaviour.
