GPM Racing Aluminium Front / Rear Upper Arms - 14pcs Set for Traxxas 1/10 MAXX (TXMS054F/R)

Engineered aluminium upper arms for TRAXXAS MAXX platforms

This 14 pcs upgrade replaces stock front and rear upper arms on TRAXXAS MAXX Monster Truck platforms with CNC-style aluminium components specified for hobbyists seeking improved control. The geometry is preserved while axial and radial play at pivot bores is reduced for more consistent suspension behavior.

Material specification remains 6061 T6 aluminium for the arm bodies, with injected Delrin collars pressed into the bore to stabilise bearing seating. Fastening uses stainless steel locating pins and countersunk flat head screws in a pin-plus-screw retention layout to reduce thread wear from vibration and loose parts.

Intended for drivers refining suspension setup, this kit gives a firmer linkage response and repeatable alignment under high-load off-road scenarios while maintaining compatibility with stock bearings, ball-ends, radio gear and servo mounts.

How do Delrin collars improve pivot stability?

Delrin collars act as an interference fit inside the bore to reduce axial and radial movement, improving bearing preload consistency and lowering slop at the ball end interface.

What torque practice is recommended for the flat heads?

Use light even torque to seat the screws without crushing the Delrin collar; secure locating pins first, then final-torque the flat head screws.

Are additional shims required for alignment?

The arms are dimensioned to match stock geometry, so shims are normally unnecessary; use shims only when making fine toe or camber adjustments.

Can these arms be resurfaced after damage?

Minor nicks can be dressed, but significant deformation or cracked Delrin collars require replacement to maintain correct bearing alignment. Write Product Review Please sign in your account before you can write any review. Sign In Close
