Traxxas E-REVO Rear Upper & Lower Aluminium Suspension Arms ER5657 by GPM  [ER5657]

Rear aluminium arms for E-REVO setups

This 4pcs kit is an aluminium rear upper and lower suspension arm set made as a drop-in upgrade for Traxxas platforms. The metal arms are supplied to replace factory plastic parts and change rear linkage stiffness and long term durability on E-REVO style chassis layouts.

Installation notes: these arms are intended to reuse existing mounting points on compatible Traxxas rear hubs and chassis rails. Verify pivot pin clearance, confirm original screw length and thread engagement, and fit-check before final assembly. If you swap mounting hardware, apply an appropriate thread locking compound to metal-to-metal fasteners and cycle the suspension to ensure unrestricted travel.

Tuning impact: fitting aluminium rear upper and lower arms alters flex characteristics and typically reduces progressive deflection under load, which can stabilise rear alignment during acceleration and cornering. Treat the arms as part of a balanced setup change alongside damper and anti-roll adjustments rather than a single cure-all.

For hobbyists wanting a metal alternative to the factory plastic rear arms on Traxxas E-REVO family vehicles, this 4pcs aluminium set offers increased wear resistance and predictable suspension behaviour; always confirm fitment on your specific chassis before modifying hardware.
