This is a set of ONE upper and ONE lower rear control arms for the HPI Baja 5B and Baja 5T series of vehicles.  Two months prior to the release of these rear A-arms for the HPI Baja 5B &  5T, RPM released their version of the front A-arms. In that short amount of time, the durability of the RPM Baja A-arms displayed their unbeatable nature! That kind of performance can now be matched out back with their rear A-arms for the 5B & 5T.

RPM Baja rear A-arms start with the basic geometry of the stock arms so they are direct replacement parts – no additional parts will be needed. However, RPM has made a number of modifications  to the arms to improve performance and durability.

Key durability features are as follows:

  • The shock mount on the lower A-arm has been moved forward by a full Ό” to eliminate the severe rubbing issue of the wheel at the shock mount that would cause stock arms to break.
  • By moving the shock mount forward, RPM was able to increase the material around the shock mount to protect the lower shock rod end, preventing it from being the lowest hanging component of the A-arm assembly.
  • RPM has incorporated a third inner hinge pin boss at the inside hinge pin of the lower A-arm and tied in structural ribs that help disperse impact energy and rotational forces from engine torque over all three hinge pin bosses.
  • Similar corner webs to those found on RPM's front A-arms have been designed into the rear upper and lower A-arms as well to help improve strength and durability.

In the performance department, RPM moved the rear hub carrier forward by 1/8” over stock geometry. While this does little to change the overall wheelbase of the vehicle, what it does do is alter the angle of the drive shaft as it exits the differential. This reduces the tendency of the Baja to squat under acceleration. This happens when the torque of the motor is opposed by the force of friction created by traction at the rear tires causing chassis squat, consequently causing a loss of grip. By sliding the rear hub carrier forward, the torque of the motor effectively “pushes” the rear wheels into the ground, using both the weight of the Baja and the torque of the motor to improve acceleration performance. Up top, RPM rear upper A-arms have had a shape change for added lateral stability – the stock “Y” shape tends to allow the upper pivot ball to move forward and backward while the RPM  “D” shape holds the upper pivot ball in place more solidly, providing a more consistent feel to the performance of the Baja.

Just like their front arms, RPM mold's their Baja 5B / 5T rear A-arms in both a stealthy black and a dyeable white version for those that like to personalize their vehicles. A little Rit clothing dye, some hot water and our dyeable A-arms can be dyed to any color you prefer!

Tech Notes: RPM Rear A-arms for the Baja 5B & 5T are sold in sets consisting of one upper and one lower A-arm. Two sets will be needed to complete one vehicle.
