Description

The Swift Springs 140-300-450 is a high-performance coilover spring engineered to elevate your vehicle's suspension capabilities. Featuring a precise spring rate of 450 lbs/inch, it delivers a firmer ride that enhances cornering and stability without compromising overall comfort. Constructed from H5S.TW material, these springs offer superior performance compared to standard silicone chrome steel alternatives. The design minimizes deflection, ensuring a consistent spring rate and preventing common issues like rubbing against shock bodies. With a usable stroke of 7.3 inches and a maximum stroke of 8.5 inches, the spring allows for significant suspension travel, crucial for maintaining traction and control during aggressive driving maneuvers and absorbing impacts from rough terrain. These coilover springs are designed with a universal fitment in mind, offering a versatile option for enthusiasts looking to upgrade their existing suspension setup. The robust construction supports a maximum load of 3825 lbs, making it suitable for a variety of applications and driving conditions. Customers have reported noticeable improvements in vehicle responsiveness and confidence when taking corners, along with better traction during acceleration.
