Description

The Swift ID 65mm x 7" x 24.0 KGF/MM coilover spring is engineered for enthusiasts seeking enhanced performance, traction, and ride quality. Manufactured with Swift's proprietary H5S.TW material, which surpasses silicone chrome steel, these springs offer a lighter, more durable, and compliant solution. This advanced material allows for fewer coils, leading to reduced unsprung weight and an increased usable stroke of 68mm (2.7 inches), with a maximum stroke of 101mm (4.0 inches). Users can expect a noticeable increase in traction, smoother weight transfer, and improved ride quality. Furthermore, they contribute to lower tire temperatures and a more predictable feel during spirited driving or racing. The 65mm inner diameter and 7-inch length, combined with a 24.0 kgf/mm (1,344 lbs/inch) spring rate, make them suitable for various performance setups. Each pair includes two Swift springs.
