AST Suspension builds some of the most precisely engineered dampers available for performance and competition vehicles. Whether you're building a dedicated track car, a dual-purpose street/track machine, or a show car that needs dialed-in stance and handling, AST's lineup of coilovers and shock absorbers delivers the adjustability and build quality serious drivers demand.

Popular Upgrades

The AST 4100 series coilovers are a favorite for street-driven enthusiasts wanting meaningful performance gains without sacrificing ride quality. The 4150 and 5100 series step up to more aggressive damping curves suited to autocross and circuit work. AST also offers remote reservoir setups and custom valving for purpose-built race applications where every tenth matters.

Are AST coilovers adjustable for ride height?

Yes. AST coilovers feature threaded spring perch adjustment, allowing you to dial in ride height independently of shock travel. Many models also offer rebound and compression damping adjustments so you can tune the setup to your driving style and track conditions.
