TRAXXAS Revo/Summit Alloy Front Lower Arm TRV055 by GPM  [TRV055]

Technical overview of the alloy sandwich lower arm

This alloy front lower arm is an aftermarket replacement developed for TRAXXAS Revo series trucks. The sandwich construction combines a machined alloy arm section with steel fasteners and Delrin collars to retain pivot pins, delivering a stiffer control link compared with standard plastic arms while remaining accessible for routine servicing.

Dimensional fidelity is maintained to ensure direct swap-in compatibility with the listed TRAXXAS models. The arm preserves factory mounting geometry so it integrates with existing steering knuckles, dampers and suspension links without chassis modification. Delrin collars reduce direct metal contact at pivot interfaces and help control wear under load.

In tuning applications the arm changes stiffness characteristics at the lower control point and will alter vehicle feedback when paired with different spring rates, shock fluids or anti-roll bar settings. Use this component to increase lower link rigidity or as a durable replacement where stock components are prone to damage.

A precision upgrade aimed at hobbyists seeking robust, serviceable suspension links that maintain factory geometry and enable consistent tuning results.
