RPM Rear Upper & Lower A-Arm For HPI 5B/5T (Dyeable White) #82251


Description:

The product is sold in sets consisting of one upper and one lower A-arm. Two sets will be needed to complete one vehicle.

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.
