Suspension techniques

A company driven by passion; ST is committed to developing innovative suspension solutions for today’s enthusiasts who demand style, performance, handling, and safety.
True enthusiasts demand ST.

Green means GO on a new era at ST Suspensions
The recent integration of ST into the KW automotive group has greatly expanded our manufacturing capabilities. Both our American and European based manufacturing facilities are equipped with contemporary CNC operated machines and computer supported production and assembly lines to ensure that rigorous quality standards are upheld.

For the ultimate in performance, style, and handling; choose ST height adjustable Coilover kits. The threaded shock bodies allow you to customize your vehicle’s ride height to the max, without compromising safety, functionality, or driving performance. Each application is thoroughly engineered and tested under road and track conditions by our European manufacturing facility to ensure it meets the highest quality standards of the German TÜV.

Sport Suspension Kits
Take the guess work out of suspension tuning with ST Sport Suspension kits which are professionally designed to meet the demands of the enthusiast. Utilizing our Sporttech or Speedtech springs, mated with perfectly matched ST Sport Shocks, these complete packages offer significant improvements in handling and grip.
ST offers the best anti-sway bar / lower tie brace combination kit on the market. By integrating an adjustable lower tie brace to tighten and strengthen the rear lower sub-frame with a rear anti-sway bar featuring adjustable end-links, these kits can be set up for street or race applications. With the added benefits of urethane bushings, anodized brackets, complete hardware, and easy to follow installation instructions, this innovative ST suspension solution is the ultimate handling upgrade for your import performance vehicle.

For the everyday enthusiast, the ST sport shocks are an absolute must! Designed exclusively for lowered vehicles, our advanced valve tuning is targeted at controlling the higher spring rates associated with performance lowering spring. Our reduced rebound travel optimizes the piston stroke of the shock absorber guaranteeing a balanced chassis under any circumstance. With the ST sport shocks on board, you can carve the canyons in comfort and style.

Complete assemblies feature:

  • Low pressure gas-hydraulic design
  • Twin tube construction
  • Teflon seal technology
  • Optimized rebound travel

    For the ultimate handling of your Muscle Car, look no further than ST Suspension’s range of coil spring and anti-sway bar performance products. ST offers heavy duty stock-height coil and leaf spring applications for the enthusiast wanting to restore their muscle car to stock, or lowered-height Muscle Car Sport Springs for the more performance craving driver looking for an aggressive look with improved performance. To further improve handling, install a set of thicker ST anti-sway bars with polyurethane bushings to reduce body roll and give you better control of your performance vehicle.

    Polyurethane Bushings Kits
    Complimenting our Muscle Car line is our full line of polyurethane suspension bushings. These bushings are designed to improve your handling, and are engineered differently than OEM rubber components to be a free floating and non-binding design.

    Pivot Bushings and Brackets/ End Link Assemblies
    Manufactured with polyurethane, ST Suspension offers you anti-swaybar replacement bushings. Eliminating anti-sway-bar deflection and reducing body roll, ST replacement bushings offer durable performance. Improve your anti sway-bar response and gain vehicle control using ST Suspension End-Link Assemblies. These kits include heavy duty urethane grommets and high grade plated hardware. A combination of both ST Suspension pivot bushings and end link assemblies will give performance handling and better control of your vehicle.
