Description

Engineered with Swift Springs USA's proprietary HS5.TW material, this spring is optimized for corner-specific performance, aiming to maximize vehicle potential and leverage every advantage. This particular spring has a length of 8 inches and an inner diameter of 1.88 inches, with a spring rate of 400 lbs/inch. It offers a usable stroke of 3.9 inches and a maximum stroke of 4.3 inches, capable of handling a maximum load of 1,717 lbs. The straight-type design ensures straightforward integration into compatible coilover systems. While this spring is designed for broad motorsports application, potential buyers should be aware of specific fitment exclusions noted for other K-Tuned spring models, such as the Swift Springs (12K-22K) which will NOT fit the rear of RSX/EM2/EP3 Coilovers or the front of S2000. It is recommended to verify compatibility for your specific application.
