Enhance your suspension with 70mm ID Swift Springs, the go-to choice for racers and enthusiasts seeking more stroke, improved handling, and reduced unsprung weight. With Swift Racing Springs, the only thing you'll be shedding is lap time!
For over 90 years, Swift Springs has led the industry in precision spring manufacturing. Their engineers have meticulously designed and refined Swift Coilover Springs to deliver superior performance, ensuring a lightweight, durable, and consistent spring that maintains precise linear rates.
Unlike conventional springs that only offer a stiffer or softer ride, Swift Racing Springs provide increased traction, smoother weight transfer, better ride quality, lower tire temperatures, and a more predictable driving experience. Swift has taken the "what if" of suspension tuning and turned it into a proven competitive advantage.
Available in a variety of sizes, Swift Springs metric coilover springs feature inner diameters ranging from 60mm (2.25in) to 70mm (2.75in), lengths from 127mm (5in) to 280mm (11in), and spring rates from 3kg (168lbs) up to 34kg (1900lbs). Whether you're upgrading your daily driver or fine-tuning your track setup, Swift Springs has the perfect coilover springs for your needs.
Upgrade to Swift Racing Springs today and experience the difference that precision engineering makes!
