Coil Springs, 1.4" Drop

Constructed from SAE 9254 spring wire, these springs undergo rigorous heat treatment processes during manufacturing. This ensures an exceptionally high tensile strength and uniform spring rates, which are crucial for resisting premature sagging and maintaining consistent performance over time. The primary benefit of these lowering springs is the improvement in vehicle handling and responsiveness. They are precision-tested to deliver outstanding control and balance throughout the suspension system. The springs are engineered to work seamlessly with factory or compatible aftermarket shocks, offering a significant drop of 1.4 inches at both the front and rear. These springs are specifically designed for the 2011-2017 Buick Regal 2WD models. The design aims to lower the vehicle's center of gravity, enhancing its stance and visual appeal while also contributing to better cornering performance. Despite the performance enhancements, the springs are tuned to provide a smooth and comfortable ride experience suitable for daily driving, carefully balancing ride height with clearance to avoid bottoming out issues. Specifications include a spring rate of 4.6 kg/mm for the front and a range of 3.1-5.8 kg/mm for the rear. The kit includes all four springs required for installation.
