Coil over spring rate is calculated from the vehicle weight and the assumption that the vehicle will have two coil overs on the rear and two on the front if so engineered. The rates in our catalog relate to this formula. Thus a T bucket for example weighing in at 1700 pounds with even weight distribution front to rear calculates in at a 140 spring on each side in the rear and the maximum lean in of the shock at 20 Degrees. This is an average and in many cases individual desires or drive train variances dictate either a heavier or softer spring. If we were somehow to support the entire rear weight of same car with one spring the spring rate would need to be doubled and from an engineering standpoint there could be some variance. On spring rate there is nothing carved in stone. Horsepower, weight transfer during acceleration or braking, and particular driving habits all have an influence on spring rate to use.

There are several variables that come into play when picking springs, including the angle the coil over is at, the installed length, and the weight of the back of the vehicle. Please have that information available and give us a call and ask for one the Rod Techs, 800-979-0122
