TRAXXAS E-REVO Aluminium Rear Upper & Lower Suspension Arm 4pcs set by GPM ER5657  [ER5657]

E-REVO Rear Aluminium Suspension Arms

This is an RC-scale aluminium rear upper and lower suspension arm set supplied as a 4pcs kit for Traxxas platforms. The components are intended as drop-in replacement parts to alter rear suspension linkage stiffness and durability compared with stock plastic arms. The set is described by the manufacturer as aluminium and targets E-REVO style chassis layouts.

Installation considerations: the arms are designed to re-use existing mounting points on compatible Traxxas rear hubs and chassis rails. Check fit at the pivot pins and confirm original hardware length and thread engagement before final assembly. Apply thread locking compound to metal-to-metal screws if you replace mounting hardware, and cycle the suspension to confirm free movement through the travel range.

Tuning role: switching to aluminium rear upper and lower arms changes flex characteristics and can reduce progressive deflection under load, which affects rear alignment stability during acceleration and cornering. Use the arms as part of a balanced setup update alongside shock damping and anti-roll adjustments rather than as a sole performance change.

For hobbyists seeking a metal alternative to factory plastic rear arms on Traxxas E-REVO family vehicles, this 4pcs aluminium set provides a durable replacement with tuning implications for rear suspension behavior; confirm fitment with your specific chassis before committing to hardware changes.
