GPM Racing Aluminium Rear Suspension Arm Set (Upper+Lower) - 24pcs Set for Traxxas 1/10 E-REVO VXL (ER25657)

Precision CNC aluminium rear arms for E-REVO VXL

The ER25657 rear suspension arm assembly is a precision aftermarket solution engineered for the TRAXXAS E-REVO VXL chassis. Supplied as matched upper and lower arms, the design targets improved load distribution at the rear mounts and repeatable handling characteristics under dynamic loads.

CNC machined from 6061 T6 aluminium, each arm incorporates pressed Delrin collars at the pivot bores to maintain tight bearing clearance and reduce fretting. The anodised surface finish provides wear resistance and consistent part-to-part tolerances. A screw-lock stainless steel ball retention replaces press-fit retainers to reduce the risk of loosening under vibration and high torque events.

The kit includes 24 pieces with both arms and the full complement of pins and fasteners for direct replacement of stock rear upper and lower arms. Dual ball stud positions permit calibrated adjustments to rear roll centre and steering geometry for setup optimisation on varied surfaces.

What tolerance controls are used in machining?

Arms are CNC machined to tight dimensional tolerances with quality control checks on pivot bore concentricity and ball mount locations to ensure consistent fitment across the set.

How do Delrin collars improve pivot performance?

Delrin collars act as a low friction bearing surface inside the aluminium bore, reducing lateral play and wear at the pivot interface under repeated loading cycles.

What is the recommended fastening method for the ball studs?

Use the supplied screw-lock fasteners for the stainless steel ball retention to maintain preload and resist vibrational loosening. Torque to recommended settings in the provided assembly documentation.

Are these arms suitable for competitive tuning?

Yes. The dual ball positions and rigid aluminium construction make the ER25657 set appropriate for detailed setup work where consistent geometry and pivot stability are required for lap time improvements.
