The Swift Advantage
Built From the Metal up
Most springs are simply wound from off-the-shelf steel. Swift takes a different path. We're a metallurgy company first - creating proprietary alloys in-house to engineer springs with unmatched precision, consistency, and performance at an atomic level.

Purpose-Built Materials
Our flagship HS5.TW alloy is the foundation of Swift Springs. Developed for road racing, it delivers faster suspension response and reduces the mechanical lag between shock and spring - translating to sharper grip on track and a more compliant, confident ride on the street.
From this foundation, we adapt our metallurgy for different demands:
-
Road Racing & Track Cars
Ultra-responsive HS5.TW alloy for maximum mechanical grip.
-
Off-road & Circle Track
Enhanced blends that resist coil bind and deliver durability under extreme travel.
-
Street Performance
Springs that balance ride quality with precision handling - reason Swift first became a favorite among enthusiasts.
The difference you can feel
Every Swift Spring is designed to deliver real-world performance advantages:
-
FASTER RESPONSE
Reduced lag means shocks and springs work in perfect harmony.
-
LIGHTWEIGHT DESIGN
Reduces unsprung mass for improved handling and comfort.
-
GREATER STROKE
Longer usable travel for better control and compliance.
-
UNMATCHED CONSISTENCY
Maintains spring rate, season after season, heat cycle after heat cycle.

Proven Worldwide
From Le Mans to (Dirt/Asphalt) Late Models and Modifieds, Super GT to Formula Racing, championship teams choose Swift for one reason: RESULTS. The same technology trusted by professional racers is available for your street or track car.
