TRAXXAS Rustler VXL Front Upper Arm Precision Upgrade RUS054 by GPM  [RUS054]

Precision front upper arm for Rustler VXL

This CNC-friendly description covers the alloy front upper arm developed for the TRAXXAS 1/10 Rustler VXL platform, model RUS054. Supplied as a pair, the parts replicate factory mounting geometry to allow installation with original chassis hardware while offering the dimensional stability expected from a metal upgrade.

Installation notes: remove wheel and steering linkage to access upper arm pins, retain original hex screws and pins where fitment allows, and verify ball cup alignment prior to controlled torqueing. Standard hand tools and appropriate hex drivers are sufficient; validate steering travel and suspension droop post-fitment to prevent interference.

Tuning role: upgrading to alloy increases stiffness at the upright-to-arm junction and changes load paths through the front end. Use these arms when seeking improved wear resistance or when performing measured adjustments to steering geometry; inspect tie rods and ball studs for wear and adjust toe and camber as part of the setup routine.

Designed for hobbyists seeking a robust metal replacement or measured tuning changes; follow workshop checks after installation to maintain predictable handling and component longevity.
