Description

The K-Tuned Metric Coilover Spring offers a robust solution for both daily drivers and race cars seeking precise suspension tuning. Engineered with K-Tuned's proprietary HS5.TW material, these springs are built for durability and performance. This particular spring measures 8 inches in length and features a 70mm inner diameter, making it compatible with a wide range of coilovers. It is precisely rated at 9.0kgf/mm (which equates to 504 lbs/inch), providing a firm yet responsive ride. The spring's design includes a usable stroke of 104mm (4.1 inches) and a maximum stroke of 135mm (5.3 inches), allowing for ample suspension travel while maintaining control. It is important to note that these springs are sold exclusively in pairs to ensure consistent performance and balance for your vehicle's suspension system.
