The GPM ER25657 rear suspension arm set is an aftermarket aluminum upgrade designed for the TRAXXAS E-REVO VXL platform. Built as an upper and lower rear arm kit, it targets improved rear chassis support and predictable handling during acceleration, braking, and cornering on RC models.
Construction uses 6061 T6 aluminum with Delrin collars pressed into mounting points to reduce play and strengthen the pin interface. The arms are CNC machined with anodized finish for corrosion resistance and consistent fit. GPM revised the stainless steel ball retention to a screw-lock design to improve joint security compared to stock press-fit methods.
The kit is delivered as a 24 pcs set that includes the suspension arms plus the fasteners and pins needed for installation, allowing direct replacement of the rear upper and lower arms without fabricating additional parts. Dual ball-position holes are provided on each arm so the roll center and steering geometry can be tuned for different track or surface conditions.
For drivers seeking a firmer rear end and easier geometry adjustments on the E-REVO VXL, this GPM aluminum arm set provides a direct-fit upgrade that focuses on durability and tuning flexibility while retaining OEM-style mounting.
