Moog Coil Springs by Size

If you haven't been able to find the right coil springs for your vehicle check out this Moog Coil Spring Chart that lists all of the specifications you need to find the right suspension springs.

Sagging coil springs can affect your ride height as well as your handling ability and this only gets worse the more they age. Depending on the state of your OE coil springs you could increase your ride height significantly by simply replacing them with new springs. If you're looking for dual rate coil springs that can cut down on body roll when taking corners at high speed in your car, or heavy duty coil springs to increase the carrying or towing ability of your truck or commercial vehicle, this list will have something for you.

This moog coil spring catalog gives nine specific dimensions for each coil spring so you can find exactly what you're looking for. The following categories define the different characteristics and dimensions of suspension coil springs to help you decide which set is the best for your application.

- End Type
- Free Height
- Installed Height
- Inner Diameter
- Bar Diameter
- Coil Spring Rate
- Load
- Coil Spring Type

If you need any help navigating the parts please contact our customer service specialists who can help you find the coil springs you're looking for.

How to Measure Coil Springs

End Type

Coil Springs have three types of ends: Square, Tangential and Pigtail. It is important that you select a coil spring that matches BOTH your end types, otherwise the coil spring won't fit. Your OE coil spring could have the same type ends, or a combination of both.

Type 1: Squared

With a Squared end, the final coil is bent back to touch the coil before it. The easiest way to know if you have a squared end is to stand the coil spring straight up. A squared end will let the spring sit flat on the ground and stay standing.

Type 2: Tangential

A Tangential end looks like it would just keep on going forever if the spring continued. The last coil is not bent back and it is not the pigtail (see below). Instead, the tangential coil spring looks as though a normal coil was just cut, otherwise it would have kept winding on forever. If you tried to stand it up straight, it would fall.

Type 3: Pigtail

The Pigtail is probably the easiest to identify. Its defining characteristic is the pig tail shape at the end. The final coil is squared off, but is a much smaller diameter than the rest of the spring.

Free Height

The free height of your coil spring is the length of your spring while it's just laying on the ground. Measure the spring from end to end with no weight on the coil to get the free height.

Installed Height

The installed height is a little more difficult to measure. The installed height is the length of the spring while installed on the car. Simply put, the installed height is the free height put under load.

Inner Diameter

The inner diameter of the coil can be measured with a tape measure once the spring is off. Measure the distance across the spring from inside the coils.

Bar Diameter

The bar diameter (coil thickness) can be measured easily with a digital caliper.

Spring Rate

The spring rate is pretty difficult to calculate without a relatively complicated machine. The spring rate is the amount of weight it takes to deflect the spring one inch while it is under load. In other words, you would have to have a machine that would compress the spring to the install height first. Then, you would have to see how much weight it would take to compress the spring one more inch. The higher a spring rate, the stiffer the spring. The lower the spring rate, the softer the spring.

Load

The load of a spring is the amount of weight required to compress the coil spring from free height to install height. This is usually calculated by coil spring manufacturers using the weight of the front (or rear) of the vehicle. Air conditioning, engine size, hood weight and many other parts play a role in determining how much weight the spring will be under before there is any travel and deflection. Depending on which springs you're trying to replace, you'll need to know the weight of either the front or rear of your vehicle to correctly match a coil spring. Moog lists in the specifications the amount of weight it takes to go from free height to install height on each of their coil springs (Load).

Spring Type

Moog offers two types of springs for a universal fitment: Constant Rate and Variable Rate.

Constant Rate

Moog Constant Rate coil springs return your vehicle to the original specifications. The rate at which the spring compresses and rebounds remains constant regardless of the amount of load on the spring. These coil springs are heat treated, have a weather resistant finish and use a urethane protective tube.

Variable Rate

Moog Variable Rate coil springs can be used as an original replacement or an upgrade to carry heavier loads. The resistance changes as the spring compresses, becoming progressively stiffer as the load on the springs increase. The springs include a "comfort range" with tightly spaced coils to give a smooth ride, and include a "load range" with widely spaced coils to minimize deflection and maintain chassis height when the vehicle load increases.
