E-REVO Rear Upper and Lower Aluminium Arm Set ER5657 by GPM  [ER5657]

Technical overview - rear aluminium arms

This 4-piece aluminium rear upper and lower suspension arm set is supplied as an aftermarket replacement for Traxxas platforms. The components are intended to be fitted as drop-in replacements for factory plastic arms to change rear linkage stiffness and improve durability on E-REVO style chassis.

Assembly guidance: arms are produced to align with common Traxxas rear hub and chassis rail mounting locations. Confirm pivot pin clearance and verify original fastener lengths and thread engagement before final tightening. Use thread locking compound on metal-to-metal screws if replacing hardware and cycle the suspension to ensure full, unrestricted travel.

Performance note: replacing plastic arms with aluminium units reduces progressive deflection under load and changes flex characteristics, which affects rear alignment stability during acceleration and cornering. Use these arms in conjunction with dampers and anti-roll adjustments for a balanced handling response.

For hobbyists seeking a metal alternative to factory plastic rear arms on Traxxas E-REVO family vehicles, this 4pcs aluminium set delivers improved wear resistance and predictable suspension behaviour; verify fitment with your chassis before altering hardware.
