Description

This specific model features a 7-inch length, a 65mm inner diameter, and a spring rate of 26.0 kgf/mm (equivalent to 1,456 lbs/inch). Constructed from Swift's proprietary HS5.TW material, these springs are engineered to be superior to traditional silicone chrome steel. The material composition contributes to improved performance characteristics, including increased traction, smoother weight transfer, and a more predictable feel during spirited driving or track use. Users can expect a better ride quality and potentially lower tire temperatures due to the efficient energy absorption and distribution. These springs are sold in pairs and are color-coordinated based on their inner diameter, with a wide variety of lengths and rates available to suit different applications, from daily drivers to dedicated race cars. The specifications include a usable stroke of 67mm (2.6 inches) and a maximum stroke of 96mm (3.8 inches), providing ample suspension travel within its operational parameters.
