ST-X Coil-Over Damper Set

The ST Suspensions ST-X Coil-Over Damper Set is engineered to deliver road performance with everyday comfort for the 2013+ Ford Focus ST. This coil-over kit features an adjustable spring perch constructed from a durable, friction-optimized polyamide composite with a stainless steel insert. This design prevents corrosion between the strut and perch, ensuring reliable height adjustability over time. The galvanized zinc-coated steel struts are treated for optimal corrosion protection, extending the lifespan of the suspension components. ST Suspensions incorporates a dust protection system to shield the hardened chrome piston rod and valve packs from dirt and debris. The system is further reinforced with a multi-layered pressure-resistant sealing package, a mono block guide system, and a low-friction piston band operating within the pressure-resistant internal damper housing. These features contribute to the durability and consistent performance of the dampers. Developed with engineering from KW, these application-specific ST X Coilover kits are tuned to improve the driving experience while maintaining road comfort, making them suitable for everyday use.
