The ER25657 rear arm set from GPM is an aftermarket aluminium upgrade tailored to the TRAXXAS E-REVO VXL. This upper and lower rear arm kit strengthens the rear axle area and gives a more controlled feel during acceleration, braking and cornering for hobbyists who tune setup.
Manufactured from 6061 T6 aluminium, the arms include pressed Delrin collars at pivot points to cut down play and protect the pin bore. CNC machining produces consistent geometry and the anodised finish improves surface durability. GPM also swapped the ball retention to a screw-lock design to minimise loosening versus stock press-fit parts.
The set is supplied as a 24 piece pack containing the arms and all necessary fasteners and pins for direct replacement of rear upper and lower arms. Dual ball-position holes allow quick changes to roll centre and steering response to suit different track conditions.
For off-road drivers wanting stronger rear components and easy geometry tweaks, this aluminium arm set provides a direct swap that focuses on toughness and setup versatility.
