Description
The Traxxas X-Maxx and Funco Pro Scale Race Replica hit hard! Stock A-arms simply can’t keep up. As soon as Traxxas released the X-Maxx, RPM customers demanded stronger suspension arms built to handle the size, weight and punishment these monsters deliver. Our engineers studied real-world failures and analyzed broken stock arms to identify every weak point.
The result is the strongest, lightest X-Maxx | Funco A-arms available.
We built the upper A-arms using proven RPM designs from past high-impact platforms to deliver serious strength where it matters most. For the lower A-arms, we improved ground clearance and adopted a cross-section inspired by our battle-tested 1:5-scale HPI Baja arms. That design brings true big-scale toughness to both the X-Maxx and the rear suspension of the Funco Pro Scale Race Replica.
A double support beam in the lower arms spreads impact energy across a wider area, reduces stress concentrations, and helps prevent breakage during brutal crashes and hard landings. Hit something hard? Keep driving. No walk of shame required.
Even better, every RPM X-Maxx A-arm fits any corner of the truck, eliminating the guesswork of matching specific arms to specific locations. Those same arms also bolt directly onto the rear suspension of the Traxxas Funco Pro Scale Race Replica, giving Funco owners the same legendary RPM durability.
We mold our X-Maxx and Funco-compatible A-arms from our trademark blend of ultra-tough engineering-grade nylons and proudly manufacture them in the USA. We back every set with our industry-leading limited lifetime warranty against breakage, so you can bash harder with total confidence.
Tech Notes: Each package includes one upper and one lower A-arm. This kit replaces the stock upper A-arms from #7729 or #7829. It also replaces stock lower A-arms from #7730, #7731, #7830 or #7831.
X-Maxx – Four packages complete both the front and rear of one full vehicle.
Funco Pro Scale Race Replica – Two packages complete the rear suspension.
Tip: Most users won’t need any additional parts. For heavy-duty bashing, massive jumps or extreme power systems, RPM recommends upgrading the lower A-arm hinge pins to RPM #70510 Threaded Hinge Pins (sold separately).
