Looking to improve the handling of your vehicle? Our ST Anti-sway Bars are the ideal solution. By upgrading the anti-sway bars you reduce the amount of body roll and ensure improved handling while providing better traction. ST Anti-sway Bars improve the driving dynamics of your vehicle and complete your suspension upgrade. Our ST Anti-sway Bars are made of cold-formed heavy duty aircraft steel. The reduction in the wheel load differential between the outer and inner wheel in a curve will be immediately noticeable. Depending on the vehicle, some of our ST Anti-sway Bars are adjustable to give you the freedom to fine tune the force and further improve your vehicle's lateral stability and cornering grip. Our high performance ST Anti-sway Bars go through multiple quenching and tempering processes along with a final epoxy coating to maximize the protection from extreme weather and road debris. Not only do they look good, they are also built to last.

Due to the improved lateral control, reduced tendency for body roll, and the minimized load differences between the outside and inside the wheel in a turn; you will feel more direct handling when going into curves or with fast load changes.

Who Is ST Suspensions?

ST Suspensions (under the name Suspension Techniques) is a Southern California-based company that started back in the early 1980s. Suspension Techniques developed a wide range of innovative products and solutions in response to market demands for better suspension parts. Using only the best materials, cutting-edge technologies, and streamlined processes, ST was able to offer excellent value for their products in the automotive aftermarket. Not long after its inception, ST Suspensions garnered a solid reputation in the sport compact suspension tuning industry. This led them to even greater success as countless tuners and enthusiasts all over the globe came to trust and choose ST Suspensions for their driving needs.

The Sporttech & Speedtech lowering springs along with the ST way bar kits became a household name in the tuning scene in the '80s and '90s. And, in 1995, this newfound success attention attracted a new owner, Belltech Sport Trucks, who brought a whole new dimension to the ST lineup. With this acquisition, the ST brand was relocated from Southern California to Fresno, CA.

Bought By KW Coilover

ST was later bought by German Suspension manufacturer KW Automotive GmbH in 2005. Well known for its internationally renowned KW Coilover height adjustable suspension systems, the company purchased both Belltech Sport Trucks and Suspension Techniques to launch KW Automotive North America Inc. Having such extensive resources and backing one of the leading suspension manufacturers in Europe, ST Suspensions was able to innovate itself and develop products that match and exceed those produced by other brands on the market. Rocking its current nameplate of ST Suspensions, the brand boasts an impressive lineup of race-winning technology that has been expertly re-engineered for street cars in all markets (America, European, and Asian).

Commitment to Quality Products

The infusion of ST's new parent company took the suspension brand to the next level, expanding not only its application range but also adding the innovative ST Coilover program modeled after the KW Variant 1 coilover design. Today, ST Suspensions is pleased to offer some of the best suspension packages available on the market. Its kits are designed to work well not only on the street but on the track as well.

The ST Suspensions team uses high-quality materials that will not break easily, even under excessive heat and stress. That is why tuners and racers all over the world choose ST Suspensions for all their handling needs. What's more, all ST Suspensions' parts are designed to fit perfectly in the original part location without any modifications needed. This allows the end-user to simply bolt on the part and go for a seamless installation process and quality customer experience.

Why Choose ST Suspensions?

The ST Suspensions brand is catered toward demanding customers who want only the highest quality suspension parts for their vehicles. By bringing together its American and European product portfolio, the ST team was able to create its most extensive range of products so far. From springs, dampers, suspensions, height adjustable coilover kits, anti-sway bars, and other suspension components, its products are widely recognized for their unparalleled quality and performance, all at affordable price points. ST's overall goal remains to provide every car enthusiast with the right suspension parts that will deliver optimal handling and driving dynamics without compromising ride quality. The brand has, therefore, intensified its R&D efforts and consistently extended its range of parts to include more makes and models across all markets.
