TRAXXAS E-REVO Aluminum Upper and Lower Arm Set ER24567 by GPM  [ER24567]

Aluminum suspension arm upgrade for TRAXXAS E-REVO

This aftermarket arm kit replaces the stock plastic upper and lower arms on TRAXXAS E-REVO models with machined aluminum components to reduce flex and stabilise the chassis during aggressive driving and tuning. The set covers both front and rear locations to deliver a uniform improvement across all axle assemblies.

Supplier details indicate 6061-T6 machined aluminum for strength-to-weight balance, with Delrin pivot collars around the hinge areas to cut lateral play and sharpen pivot tolerances. The arms are CNC machined and anodised, and the ball mount system moves to a screw-lock style for more reliable retention. Rear arms feature dual ball-stud positions so you can tweak knuckle geometry for different surfaces.

In service, these arms are intended to support knuckles, reduce unwanted deflection under load, and offer additional setup choices for suspension geometry. When fitting, check hinge pins, ball studs, and related hardware for wear and use the supplied or equivalent fasteners to ensure secure mounting. This part is for model use only and not for full-scale vehicles.

For builders wanting firmer chassis response and cleaner tuning adjustments on a TRAXXAS E-REVO, the aluminium upper and lower arm set gives an effective way to cut flex and expand adjustment without changing the drivetrain.
