Progressive Rate Front Coil Springs

The TEIN S.Tech Spring Kit offers an excellent step towards suspension tuning, providing an approximate 1.5-inch drop for a more aggressive stance and enhanced road-holding capability. Constructed from durable Chrome Vanadium SAE9254V, these springs are built to withstand rigorous road conditions. The progressive spring rate design contributes to a smooth ride, even on uneven surfaces, while a stylish green powder coat finish offers both aesthetic appeal and protection against the elements. Certain applications may include TEIN Silencer Rubbers to minimize noise and further enhance comfort. This kit includes four lower springs, warranty information, a bump stop reference guide, and potentially TEIN Silencer Rubbers and stickers depending on the specific application. The front spring rate is 3.1 kgf/mm (168 lbs/in), and the rear spring rate is 2.7 kgf/mm (112 lbs/in). Front ride height change ranges from -1.2 to -1.7 inches, and rear ride height change ranges from -1.3 to -1.7 inches. TEIN provides a 1-year limited warranty that covers defects and sagging beyond 5mm, breakage, deformity, and noise. Fitment is confirmed for 2005-2008 Chevrolet Cobalt SS FWD models, and the product page offers a search tool to verify compatibility with a wider range of vehicles. It is crucial to confirm fitment before ordering to avoid potential issues.
