The Stage 4 suspension system for the 2003-Current 4Runner is an entire new level of suspension. The front suspension is similar to the Stage one, two and three systems. The rear suspension is really where the difference is going to be seen and felt. The rear springs in the system give the 4Runner 2" of lift and the rear links help manage that suspension to cycle properly.

The biggest improvement in the system compared to the other three is the 2.5" Diameter Rear Piggyback Shocks. These shocks are tuned specifically to give your 4Runner a balanced and smooth ride quality. These shocks have a built in bump zone to increase your compression valving and the final two inches of up travel; this prevents the harsh bottom out sensation and gives the vehicle a much more controlled ride quality.
