Your cart is empty.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 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 and #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 CEN #GS025 threaded hinge pins (not included).

Love the new color but especially the feel of new arms. I bashed a couple times with my xmaxx, took a beating.

I just hit a pole around 51mph and these arms didn't break. Other parts of the truck did but not these rpm arms and so far so good

These are not the quality I have grown to expect from RPM. I ended up purchasing a set of HD arms because these were so bad.

Much stronger than stock. I suggest buying threaded hinged pins because RPM A-Arms flex.

I ordered this and wasted my money. I'm constantly losing pins due to the flex of this plastic. None of the stock ones lose pins just this one.. upside is it hasn't broken yet... its costing me money constantly replacing pins though.. super let down. I gave it two stars instead of one because I liked the color and shipping was prompt.

These parts will be an upgrade to stock parts once I break the stock parts I hope. They have a different design than stock and seem a bit stiffer
