Founded in 1979 in Southern California as Suspension Techniques, ST Suspensions was later acquired by KW Automotive in 2005, bringing German engineering excellence to their North American lineup. Today, ST offers a wide product range—including height-adjustable ST X, XA, XTA, and XTA Plus 3 coilover kits, spring kits, anti-sway bars, and wheel spacers—building on KW’s renowned suspension platforms.

All ST coilovers feature galvanized threaded bodies, with options for rebound and compression damping depending on the model (e.g., XTA Plus 3 offers 2-way adjustability and top mounts). Enthusiasts and community feedback confirm—they’re essentially KW V1-level performance at a friendly price, with robust ride feel and tuning potential.

With thousands of vehicle applications and support from live chat, dealer networks, and ST’s USA team, ST Suspensions delivers dependable, customizable performance upgrades rooted in motorsports pedigree—for street, track, and everything in between.
