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 RPM lower A-arms have a redesigned center brace structurethat 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! Next, we incorporated a unique lower A-arm skid plate that completely covers & protects the lower shock mount.
A-arms are supplied 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.
