The steps below will help you to find an approximate spring rate for your coil-over application. Enter your suspension measurements in the white boxes below. This calculator will only give approximations depending on the accuracy of your information. Use at your own discretion.
Spring rates refer to the stiffness of a vehicle's suspension springs. They are usually expressed in units of force per unit of deflection, such as pounds per inch (lb/in) or newtons per millimeter (N/mm). The spring rate determines how much the spring will compress or extend under a given load.
Hyperco's spring rate calculator helps you find the specs you need for automotive suspension springs and wheels.
May 10, 2018 · The diagram below shows a coil spring along with the following important parameters that are required to calculate the spring rate. The important parameters are: L = Free Length of The Unloaded Spring (m) G = Shear Modulus of Rigidity of Material; d = Wire Diameter (m) D = Mean Diameter (m)
This is a robust spring force calculator that gives you custom spring 3D CAD files, blueprints/spec sheets and an online spring force tester to test your spring force visually.
