The Swift Springs 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.

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.

In Swift’s impressive motorsports history dated back to 1998, first was with Nissan Skyline GT-R in the Super Taikyu Endurance Championship series in Japan. 

Then Swift got involved with the championship teams in:

    • Le Mans 24hrs
    • Nurburgring 24hrs
    • Super GT (JGTC)
    • Super Taikyu Series
    • D-1 World Grand Prix
    • F3
    • F3000
    • Formula Toyota
    • Circle Track Racing (asphalt/dirt)
    • And many other world class races!
