Ridetech Coil Spring 12in Free Length 400 lbs/in 2.5in ID

Ridetech is well-known for its performance suspension components, and this coil spring is a great example of their focus on quality parts for custom builds. This spring measures 12 inches in free length and has a spring rate of 400 pounds per inch, with a 2.5-inch inner diameter. It's designed to work with many coilover shock bodies and is a popular choice for enthusiasts looking to fine-tune their vehicle's ride height and stiffness.

The 400 lb/in spring rate offers a noticeable increase in stiffness over stock springs, which can help reduce body roll during cornering and improve handling response. The 2.5-inch inner diameter is a common size for many aftermarket coilover systems, making it versatile for various applications. While this is a universal part, it's often used in custom suspension setups where precise control over spring rate and length is important for achieving the desired stance and performance.
