Swift Springs – The Science of Winning – Not all springs are created equally. That’s why we dedicate to developing the best quality to maintain consistency.

From HPDE events to SCCA competition, Swift Spec-R Sport Springs are made for the track enthusiast looking to take their vehicle to the next level.

Swift Spec-R Sport Springs were engineered with 3 characteristics in mind – Modified ride height compared to Sport Springs to maximize optimal suspension geometry – Further increasing the spring rate to enhance overall performance. The increase in spring rate is based on the upper limits of the vehicles factory shock valving – Maintaining optimal comfort level for street use.

Spec R springs are wound with the same engineering and material as our sports springs. With the exception of stiffer rates and slight change in ride height; you can expect the same characteristics as our sports springs.
