All of our current chassis use a 3 link based rear suspension. They all have trailing arms but the top link canbe configured differently.

Standard 3rd Link - A standard 3rd link normally has rubber bushings on at least one end. It controls axle torque for both braking and acceleration. This is simple, light and inexpensive.

Push Pull Link - This 3rd link set-up isolates braking and acceleration forces with two separate rods; one is loaded when pulled (accelerate) and the other when pushed (braking). This allows for more adjustment but it is a little more complicated to set up and it weighs and costs more.

Lift Arm - This applies the acceleration torque to the lift arm and aggressively loads the rear tires. Brake torque is controlled by a separate snubber rod. Provides maximum traction but can reduce turning under acceleration. Mainly used on our Modified chassis and is better suited to classes with more power then tire.
