Ridetech Coil Spring 10in Free Length 550 lbs/in 2.5in ID

This Ridetech coil spring measures 10 inches in its free length and has a spring rate of 550 pounds per inch, with a 2.5-inch inner diameter. These specifications are important for tuning your suspension's stiffness and ride height. A 550 lb/in rate means the spring will compress one inch for every 550 pounds of force applied, offering a more controlled and responsive feel compared to softer springs.

The 2.5-inch inner diameter is a common size for many aftermarket suspension setups, making it a versatile choice for custom builds or replacements. While this is a universal part, careful consideration of its dimensions and spring rate is crucial to ensure it works correctly with your specific vehicle's suspension geometry and weight. It's designed to work with coilovers where spring length and rate are critical tuning elements.
