These aluminium front and rear upper arms are engineered as a direct aftermarket swap for the TRAXXAS 1/8 X-Maxx. Supplied as a single pair, they replace the original arms to provide a firmer pivot for suspension links and to reduce chassis-induced flex under high load.
From a setup perspective, increased arm stiffness modifies camber and toe reactions under compression, affecting steering feedback and cornering balance. The arms are designed to accept the stock mounting pins and hardware, so no chassis or gearbox alterations are needed for installation on the intended X-Maxx chassis.
Inspection and maintenance follow common practice: monitor mounting bore wear and ball-stud seating, and verify fastener torque after initial use. Clean small burrs or light surface oxidation from the aluminium before fitting to ensure smooth operation.
For technical-minded hobbyists seeking a straightforward, stiffer upper arm option for the X-Maxx, this aluminium pair offers improved suspension rigidity and predictable handling response.
