X-Maxx Upper & Lower A-Arm (Orange)
RPM X-Maxx Upper & Lower A-Arm (Orange)
RPM Traxxas X-Maxx Upper & Lower A-Arms were developed to provide customers with stronger A-arms that could handle the weight and the punishment these massive trucks can dish out. These X-Maxx A-arms are designed to be the strongest, lightest arms available! Starting with the upper A-arm, RPM used their proven A-arm designs from past successful builds to create an upper support structure sure to handle anything you can throw at it. The lower A-arm has better ground clearance than the stock arm and has a cross section based off of the proven RPM 1:5 scale HPI Baja A-arms. They also added a double support beam on the lower arms to spread impact energy over a larger area, meaning hard hits won’t force you into the “walk of shame”. They’re also universal fit, which means they’ll fit on any corner of your truck! No more worrying which arm fits where.
RPM X-Maxx A-arms are molded in RPM's trademark blend of tough, engineering grade nylons and made in the USA. RPM X-Maxx arms are backed by RPM's industry-leading limited lifetime warranty against breakage for worry-free performance you can count on!
NOTE: Each package includes one upper and one lower A-arm. Four packages will be needed to complete one full vehicle.
