This 1pr aluminium front upper suspension arm is an aftermarket replacement intended specifically for TRAXXAS E-REVO, Revo and Summit chassis. Supplied as a matched pair, the arm is designed to provide a more stable upper pivot and consistent suspension geometry for tuning, maintenance and competitive hobby use.
The ER054 replaces the original plastic upper arm and installs using the included 3.17x84.5 steel pins and 3x8 stainless steel cap head screws. Fitment is chassis specific as listed in the compatibility box; follow standard service procedures and verify alignment, wheel offset and suspension articulation after fitting.
As an aluminium upgrade, ER054 aims to deliver a firmer pivot location and predictable wear characteristics compared with stock plastic arms; inspect pivot hardware and bearings at installation and perform initial low-speed validation before regular operation.
