RPM Front Arm for HPI Baja 5b/5T/5SC - BLACK - rp82142
8 in stock
This arm set will work both right and left hand sides, so you will need to order qty 2 to replace all the rear arms on your Baja.
RPM front A-arms for the HPI Baja 5B are designed around the stock A-arm geometry, which means they are direct fit replacements – no additional parts or accessories are needed. The list of improvements from there is extensive! To start, we’ve eliminated most of the hard rib angles in favor of smoothly contoured curves that enhance survivability during extreme impacts. Both the upper and lower A-arms incorporate much larger and stronger corner webs than the stock A-arms while the RPM lower A-arms have a redesigned center brace structure that helps the rigidity and strength considerably by spreading impact energies over a much larger area.
After extensive review of 5B A-arms in stock form, we found that the stock pivot ball socket tends to break out under certain impact conditions. We addressed this problem by adding nearly 15% more material around the diameter of the pivot ball socket and we redesigned the shape of the socket to add more support and improve crash survivability without creating any interference with suspension or steering movement. Another problem we encountered with the stock A-arms is the lack of protection for the very low-hanging front shocks. We’ve solved that problem in a couple of ways. First, we made the lower shock mount longer so no part of the shock is exposed. Next, we incorporated a unique lower A-arm skid plate that completely covers & protects the lower shock mount. This skid plate adds serious bulletproof RPM protection to the lower end of those extremely expensive shocks while adding strength and support to the whole lower A-arm. Additionally, these skid plates are reversible! Since the A-arm is angled up, only the lowest part of the skid plate (the rear area) will see the most wear. By making the skid plates reversible, the 5B owner can run the skid plates until they wear thin on the one end, swap them from one side to the other and they’re good to go for more punishment!
We have found that a large percentage of 5B owners like to personalize and customize their buggies. That is why we offer these new arms in stealthy black and fully dyeable white options. With a little Rit clothing dye and some creativity, our white A-arms can be dyed to any color imaginable! Please see our website for a couple of tips and suggestions as well as photos of RPM dyed A-arms that closely match the Baja RTR purple and the stock Baja SS orange chassis colors. RPM A-arms are sold in sets consisting of one upper A-arm, one lower A-arm, one lower a-arm skid plate, two shock spacers and two skid plate mounting screws.
