TRAXXAS E-REVO Machined Aluminium Suspension Arms ER24567 by GPM  [ER24567]

Machined aluminium arm set for E-REVO platforms

This upgrade kit swaps the stock plastic arms on TRAXXAS E-REVO models for CNC-machined aluminium arms, aimed at cutting chassis flex and delivering more predictable handling while tuning. The kit includes upper and lower arms for both front and rear axles to keep geometry consistent across the vehicle.

Fitment notes from the supplier list 6061-T6 aluminium as the core material to balance strength and weight, with Delrin collars fitted at pivot points to reduce play and protect the bearing fit. CNC anodising adds corrosion resistance, and the ball mount is secured with a screw-lock method rather than a simple ball-retainer, enhancing retention. Rear arms provide two mounting positions for the ball stud so you can refine rear knuckle angles for track or off-road settings.

The set is designed to support steering components, reduce unwanted deflection under heavy loads, and expand tuning options for suspension geometry. During installation, confirm hinge pins and ball studs are in good condition and use the supplied or equal-grade fasteners for reliable assembly. This component is intended for model RC vehicles only.

For hobbyists seeking firmer control and easier setup changes on a TRAXXAS E-REVO, the machined aluminium upper and lower arms help reduce flex and offer additional geometry options without major modifications.
