About ST Suspension / KW Automotive
ABOUT US
ST SUSPENSIONS
Founded in the early 80’s in Southern California, under the company name of Suspension Techniques. Suspension Techniques developed many innovative products and solutions in response to market demands. Utilizing quality materials, modern technologies, and streamline processes Suspension Techniques was able to provide excellent value for their product in the marketplace. Suspension Techniques soon established themselves as a recognized name in the Sport Compact suspension tuning industry. This success helped garner the attention of many enthusiasts and tuners resulting in a strong growth in the brand in the USA.
The Sporttech & Speedtech lowering springs along with the Suspension Techniques Sway Bar kits became a household name in the tuning scene in the 80’s and 90’s, being referred to in many circles simply as ST. In 1995 this attention attracted a new owner, Belltech Sport Trucks, who brought a whole new dimension to the ST lineup. With the acquisition ST was relocated from southern California to Fresno CA.
In 2005, the German suspension manufacturer KW automotive GmbH, well known internationally for their KW Coilover height adjustable suspension systems, purchased both Belltech Sport Trucks and Suspension Techniques and launched KW automotive North America Inc. With the name purchase and a formal name change of the brand to it’s current nameplate of “ST suspensions”. The infusion of the technology from ST’s new parent company took ST’s game to a whole new level, increasing not only its application range coverage, but adding the innovative ST Coilover program, which was modeled after a galvanized KW Variant 1 coilover design.
With this influx of worldwide technology, staff, and engineering base ST boasts one of the largest application ranges and largest distribution chains of any suspension manufacturer in North America.

TVR-A rebound damping::
The two-stage patented “TVR-A” technology enables the low volume flows to flow through an adjustable conical low-speed bypass at slow damper speeds and to open the main rebound valve for the large volume flows at higher piston speeds. This results in a significant increase in driving comfort without affecting the high speed in the safety-relevant area. 16 exact clicks are available for the individual setting, so that a decision can be made between more comfort or more body control.

Take control of your ride with TrackRecon and unlock a new level of precision and performance.
TVR-A rebound stage damping (Twin Valve Rebound – Adjustable):
The two-step, patented “TVR-A” technology enables the small volume to flow through an adjustable, conical low-speed bypass in the case of slow damper speeds, while in the case of higher piston speeds, the main rebound stage valve opens for the large volume flows. This provides a big improvement in terms of ride comfort without influencing the high-speed in the safety-relevant range. There are 16 precise clicks available for individual settings, so you can choose between more comfort or more body control.
TVC-A compression stage damping (Twin Valve Compression – Adjustable):
With 12 precise clicks the adjustable compression stage valve (“TVC-A”-technology) can increase or decrease the cross section in the low-speed valve to achieve either more or less compression stage damping. At the same time, in the case of sudden high piston speeds, the spring pre-tensioned needle valve and the spring pre-tensioned main valve open to their maximum valve cross section, to avoid with its blow-off characteristics undesired progressive force increase in the high-speed range. This allows a better bracing of the vehicle body and at the same time at high wheel acceleration offering more comfort than with conventional valve technology. The compression stage damper setting is always supplied in combination with a separate rebound stage setting, as only an independent 2-way damper setting allows a true performance optimization.
Continuous Lowering
The KW V3 coilover kit provides maximum or personalized lowering within its tested adjustment range. Thanks to the dirt-resistant trapezoidal thread and durable polyamide threaded ring, you can easily adjust the ride height to your preference—quickly and smoothly, even after years of use. Experience long-lasting performance and flexibility with TrackRecon.

KW V4 Coilovers – High-Performance Setup with 3-Way Adjustable Dampers
The KW V4 coilovers feature a factory-set, pre-configured damper setup, equipped with three-way adjustable high-performance dampers. Independent adjustments for rebound stage damping, utilizing “TVR-A” technology, as well as low-speed and high-speed compression stage damping with “TVCLH-A” technology, draw from the proven racing technology of the ADAC Zurich 24h Nürburgring race champion. Depending on the vehicle-specific version, the dampers are reinforced with aluminum top mounts for enhanced durability. Exclusively developed for select high-performance vehicles, the KW V4 offers unmatched control, allowing drivers to push their car’s limits with safety and precision, thanks to the advanced KW suspension technology.
TVR-A rebound stage damping (Twin Valve Rebound – Adjustable):
The two-step, patented “TVR-A” technology enables the small volume to flow through an adjustable, conical low-speed bypass in the case of slow damper speeds, while in the case of higher piston speeds, the main rebound stage valve opens for the large volume flows. This provides a big improvement in terms of ride comfort without influencing the high-speed in the safety-relevant range. There are 16 precise clicks available for individual settings, so you can choose between more comfort or more body control.
TVCLH-A compression stage damping (Twin Valve Compression Low Highspeed – Adjustable):
With 6 precise clicks in low-speed and 14 precise clicks in high-speed range of the compression stage damping, the cross sections in the valves are decreased or increased, in order to achieve either more or less compression stage damping. The “TVCLH-A”-technology has a blow-off characteristic with large cross-sections which allows high low-speed forces for an optimum bracing of the vehicle body without raising the body in the case of wheel-induced high damper speeds (driving over curbs). The separate low and high-speed setting is always supplied with an additional rebound setting (“TVR-A”-technology) for an in dependent 3-way damper setting.
Continuous Lowering
The KW V4 coilover kit provides maximum or personalized lowering within its tested adjustment range. Thanks to the dirt-resistant trapezoidal thread and durable polyamide threaded ring, you can easily adjust the ride height to your preference—quickly and smoothly, even after years of use.
