Rpm Traxxas X-Maxx Upper & Lower A-Arm Orange

Immediately after Traxxas released the X-Maxx, RPM customers started notifying us that they needed stronger A-arms that could handle the weight and the punishment these massive trucks can dish out. We reviewed numerous photos of damage to stock A-arms to see where the weak points were, then reviewed a set of new A-arms to see what we could do to improve both strength and durability.

The result… Our new X-Maxx A-arms are designed to be the strongest, lightest arms available! Starting with the upper A-arm, we used our proven A-arm designs from past successful builds to create an upper support structure sure to handle anything you can throw at it! Our lower A-arm has better ground clearance than stock A-arms and has a cross section based off of our proven 1:5 scale HPI Baja A-arms so you know they’re tough! We’ve also created 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 a 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 our trademark blend of incredibly tough, engineering grade nylons and made in the USA. RPM X-Maxx arms are backed by our industry-leading limited lifetime warranty against breakage for worry-free performance you can count on!

Tech Notes: Each package comes with one upper and one lower A-arm. This kit replaces the upper a-arm from stock Traxxas #7729 and replaces the lower a-arm from stock Traxxas #7730 & #7731. Four packages will be needed to complete one full vehicle.

Tip: For most users, any additional parts won’t be necessary. For heavy use, big jumps or extreme power, RPM recommends replacing the lower A-arm hinge pins with RPM #70510 Threaded Hinge Pins (sold separately).
