RPM Suspension Arms - Baja 5B,5T Front Up & Lwr Black RPM front A-arms for the HPI Baja 5B & 5T 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, RPM 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 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. RPM A-arms will hold their shape better and have less flex than the stock arms as well!
Tech Notes: 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. Two kits will be needed to complete one vehicle. RPM Replacement Shock Skid Plates work with RPM Baja 5B / 5T front A-arms exclusively and are sold in pairs with necessary mounting hardware. After extensive in-house review of 5B & 5T A-arms in stock form and listening to Baja owners, RPM found that the stock pivot ball socket tends to break out under certain impact conditions. They addressed this problem by adding nearly 15% more material around the diameter of the pivot ball socket and redesigned the shape of the socket to add more support and improve crash survivability without creating any interference with suspension or steering movement. While they were redesigning the pivot ball area, RPM reduced the amount of slop in the ball socket to help improve and maintain more consistent camber and toe angles for smoother, more precise steering.
Another problem with the stock A-arms is the lack of protection for the very low-hanging front shocks. RPM solved that problem in a couple of ways. First, they elongated the lower shock mount, leaving no part of the shock exposed. Next, they 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 / 5T owner can run the skid plates until they wear thin on the one end, swap them from one side to the other and theyre good to go for more punishment!
