The TRAXXAS MINI XRT VXL 3S Rear Upper Suspension Arms by GPM XRTM057 are a solid upgrade for owners wanting improved longevity and control. Made from sturdy 7075 aluminum, these arms support the chassis and help stabilise the rear hub stub axle carriers to reduce flex during hard runs.
These arms are designed to accept the outer arm pin measuring 34.2mm and are fastened with an M3 lock nut for a positive, repeatable fit. That secure connection helps maintain precise wheel alignment and predictable handling lap after lap.
