The TRAXXAS MINI XRT VXL 3S Rear Upper Suspension Arms by GPM XRTM057 replace weaker stock components with a tougher aluminium option. Manufactured from 7075 aluminium, these arms bolster the chassis and stabilise the rear hub stub axle carriers for longer service life.
These arms are made to interface with the outer arm pin at 34.2mm and are secured using an M3 lock nut to prevent loosening. That reliable fastening keeps the rear geometry consistent and improves handling predictability.
