Traxxas E-REVO Rear Upper & Lower Aluminium Arm Set ER5657 4pc by GPM  [ER5657]

Rear upper and lower aluminium arms for E-REVO

Supplied as a 4pc kit, these aluminium rear upper and lower suspension arms are an aftermarket replacement aimed at Traxxas platforms. The metal arms replace stock plastic units to change rear linkage stiffness and improve resistance to wear for E-REVO style chassis configurations.

Fit notes: arms are intended to use existing Traxxas rear hub and chassis rail mounting positions. Confirm pivot pin clearance and original fastener length and thread engagement before committing to final installation. If you fit replacement metal screws, use a thread locking product and cycle the suspension to check for full, free movement.

Tuning considerations: aluminium rear upper and lower arms alter flex characteristics and typically reduce progressive deflection under load, influencing rear toe and tracking during acceleration and cornering. Combine this hardware change with damper and anti-roll bar adjustments for best results.

For modders seeking a metal upgrade to plastic rear arms on Traxxas E-REVO family vehicles, this 4pcs aluminium set offers increased toughness and predictable suspension response; always ensure part compatibility with your chassis before changing hardware.
