The Upper StrongArm tubular control arms feature corrected ball joint angles for the lowered ride height and the length has been altered to create more camber adjustment. Injection-molded Delrin bushings with 13% Teflon are used to reduce deflection and stiction.

The Lower StrongArm  tubular control arms feature a double sheer lower shock mount for increased strength. We have also dropped the lower shock mount to increase suspension travel and altered the length to create more camber adjustment. Injection-molded Delrin bushings with 13% Teflon are used to reduce deflection and stiction.

A Front MuscleBar sway bar is included to reduce body roll and includes the PosiLink End-links that provide immediate engagement between the chassis and control arms.

Drop Spindles are used to all the use of a longer stroke shock and improve suspension geometry and bump steer. Fits 18? or larger wheels.

The Bolt On 4-Link greatly improves traction, handling and ride quality. Installation does not require any welding or major modifications to the bed floor. Includes patent-pending R-Joint rod ends to eliminate binding and noise.

TQ Series Shock Upgrade: The remote reservoir triple adjustable Coil-Over shocks feature rebound adjustment along with dual stage (High Speed & Low Speed) compression adjustment. High-speed adjustment allows tuning for impact harshness and low speed adjustment allows tuning of cornering characteristics, perfect for use on the autocross, road course and drag strip.
