Traxxas E-REVO Rear Upper/Lower Aluminium Suspension Arm Kit ER5657 by GPM  [ER5657]

Aluminium rear upper and lower arms for E-REVO

This 4-piece aluminium rear suspension arm set is supplied as an aftermarket upgrade for Traxxas platforms. The components are designed to replace stock plastic arms and to alter rear linkage stiffness and overall durability on E-REVO style chassis.

Fitting guidance: the arms are produced to mate with standard Traxxas rear hub and chassis rail mounting points. Confirm pivot pin clearance, verify original screw lengths and thread engagement, and carry out a trial assembly before final torque. If you fit new metal fasteners, use a thread locking compound and cycle the suspension to ensure full, unhindered travel.

Handling notes: upgrading to aluminium upper and lower arms will change flex characteristics and generally reduce progressive deflection under load, which impacts rear alignment stability during acceleration and cornering. Consider this change as part of a wider setup tune including shock settings and anti-roll tweaks.

For drivers wanting a metal rear arm option on Traxxas E-REVO vehicles, the 4pcs aluminium set gives a stronger alternative to plastic arms and will influence suspension behaviour; always check part compatibility with your chassis before replacing hardware.
