Our award-winning adjustable modular suspension solutions were developed and engineered for safety, comfort, and performance. They are backed by a lifetime warranty.

The relatively low initial spring rate absorbs small bumps in the road, increasing grip. It then transitions to a secondary spring rate, enhancing vehicle handling during cornering and giving you the ultimate control of your driving experience.

The third and stiffest rate assists by resisting sudden dynamic movements such as acceleration, braking, or swerving to avoid an obstacle. In doing so, the vehicle remains composed, as traction is retained at each wheel for optimum grip on dry or wet roads.

MSS Rear Ride Adjusters: The central adjuster provides a firm base for the springs to sit on. It retains spring alignment and helps the components perform to their max. It also allows for ride adjustment height by lowering the capacity by up to -50mm.
MSS Rear Ride Controller The orange spring specifically enhances performance handling and comfort on wet and dry roads.
Along with the shock absorber, the single-rated, heavy-duty spring stabilizes your vehicle during acceleration, steering, cruising, and braking.
MSS Rear Ride Enhancer The MSS Ride Enhancer keeps the MSS Ride Controller seated adequately against the suspension so you can push the limits of your car.
When cornering hard and wheels lift off the ground, the active coils of the tender spring hold the MSS Ride Controller in position.
MSS Front Ride Adjuster The adjuster has been designed to enable ride height adjustment by lowering the capacity of up to -50mm.
MSS Front Ride Controller The orange springs have been designed to manage front-end ride activity, enabling maximum comfort.
Dual-Stacked The MSS springs are designed to work in unison, ensuring that sudden vehicle movement is effectively controlled.
The dual-stacked arrangement can be carefully specified to operate at different spring rates, giving a wide range of tuning possibilities.


Thanks to its patented Triple Stack Spring Technology, MSS can deliver improved performance, comfort, and safety within one product - and without compromise- for the first time.

Superior Performance

Experience a total transformation of your vehicle's handling when driving hard. Two active springs and three separate spring rates deal with a much wider range of situations when driving near the limits. Distinct benefits from the reduced roll and pitch—whether a dive or a squat—enable you to turn sharper, brake later, and accelerate sooner, respectively.

Enhanced Sefety

Upgrade your ride quality and enjoy a smoother, quieter, and more composed drive. The dual-stacked, triple-rated springs more effectively absorb shocks and vibrations caused by bumps and rough road surfaces rather than transmitting them through to the cabin as jolting and distracting road noise.

Unparalleled Comfort

Drive with confidence, knowing that you are protected against loss of traction and control—even on wet roads. Within the dual-stacked, triple-rated spring arrangement are springs specifically designed for safety. These reduce the violent spring oscillations associated with hazardous and emergency situations, quickly transferring these forces to the shock absorber. At this point, tires recover contact with the road, and control is regained.



Easy Installation With No Modifications Needed

As a spring-only solution, our products are quicker and less expensive to fit, set up, and remove. Additionally, installation and removal require no drilling, cutting, or bending, which is highly desirable for lease car drivers.

Adjustable Ride Height

Quickly and easily change ride height right back to the original - without removing the product.

Both front and rear ride heights are easy to control and adjust, with unique mid-mount adjusters available for vehicles with limited access. Unlike traditional aftermarket suspension, our products can be returned to their original ride height, giving extra clearance for winter driving, for example.
