JK 4dr: 4" Suspension System with 8 Alpine Short Control Arms & 9550 VSS Twin-Tube.
The TeraFlex JK 4dr: 4" Suspension System with 8 Alpine Short Control Arms delivers the necessary components to lift your 4-door JK Wrangler Unlimited to conquer the most extreme trails and conditions. Features a complete set of adjustable Alpine Short Control Arms HD Forged Adjustable Front Track Bar and rear track bar bracket to optimize geometry. An adjustable rear track bar is recommended. Every TeraFlex suspension system is engineered with drivability and performance in mind.
Properly developed suspension geometry roll center and load tuning ensures that all factory stability controls remain functional and within the parameters that Jeep originally engineered into the vehicle. We recommend Falcon Performance Shocks or TeraFlex 9550 VSS Shocks. Suspension Systems with 8 Alpine Short Control Arms are offered with TeraFlex 9550 VSS Twin-Tube Shocks or without shock absorbers. Falcon Performance Shocks are available separately.
TeraFlex Suspension Systems include all the components necessary to raise your Jeep for more off-road ground clearance while maintaining good drivability on- and off-road.
