  • Upper StrongArms feature corrected ball joint angles and the upper ball joint have been moved back to allow for additional caster setting to improve high-speed stability and steering feel.  They are powder coated black and fully assembled with 1/2″ taller ball joints, bushing, and cross shafts, ready for installation. 
  • Lower StrongArms feature a double sheer lower mount for increased strength.  They are powder coated black and fully assembled with ball joints, bushing, and cross shafts, ready for installation.    
  • HQ Series Coil-Overs utilize an impact-forged aluminum body and Monotube design to deliver excellent ride quality and handling. They allow fine-tuning of the ride quality and handling the rebound knob is located at the top of the shock for under-hood access. They come standard with a 1,000,0001 Mile Warranty. 
  • Front Sway bar reduces body roll, includes billet aluminum frame straps (anodized black) and low friction bushings.
  • Bolt On 4-Link greatly improves traction, handling and ride quality. Installation does not require the any major modifications to the floor pan and requires only minimal welding to the axle tube.  The R-Joint rod ends combine the best qualities of low friction movement, lateral stability, full range articulation, and quiet operation into one special bearing that is as home on the street as it is on the racetrack!


*** How do I tell the difference between 1 and 2-piece frames?
Look at the bottom of the main frame rail under the driver’s door area. On 1-piece frame cars the bottom of the frame will be flat and smooth. This frame is often called the “California” frame. The 2-piece frame design has a rough weld seam right down the bottom center of the frame rail front to rear.
