Coil springs support the weight of the vehicle and establish the ride height. As such they are the main components in lift and lowering kits for many vehicles. But performance coil springs can also improve handling, providing the stiffness required to reduce body roll and maintain traction at all four wheels. We have constant rate and progressive rate springs, spring kits to replace air suspension systems, and polyurethane isolators.

Coil springs have 2 common specifications, free length and spring rate, although lowering and lifting springs also specify the amount they will raise or lower the vehicle. Rate is the measure of spring stiffness. If a spring compresses 1” when 100 lbs. are added, the spring rate is 100 lbs. per inch. Spring rate greatly affects handling and must be soft enough to let the suspension move over bumps, yet stiff enough to keep from bottoming or topping out.

Our spring manufacturers carefully select spring rates for each application. Many use progressive rate springs for lowering to ensure you have a comfortable ride for cruising, with the stiffness you need for spirited performance driving. Progressive springs have coils that are closer together at one end than the other. The coils that are more tightly wound provide a smooth ride, but when you step up the pace, they come together and the remaining coils compress at a higher rate, which prevents bottoming out, excessive body roll, front end dive, and acceleration squat.

Although lowering springs are a popular choice for lowering a vehicle, the downside is that most will only reduce ride height by a predetermined amount. If you want to fine tune the height, a set of adjustable coilovers is an alternative, but if you want to stay with coil springs we can offer you height adjustable springs. These springs come with threaded spring perches that will allow you to individually adjust each spring height, so you can get the perfect gap between the tire and fender at each wheel. This also means that you won’t have to get a different lowering kit if you change your wheel and tire combination.

If you have a Jeep, truck, or SUV and want to go up, we have coil springs that will raise ride height from 1” up to a towering 6” or more. However, unlike lowering kits which can often be used with OE shocks and the rest of the factory suspension, even a lift of only 1-2” may require longer shocks, and more parts and modifications are needed for higher lifts. We strongly recommend that you check out our selection of lift kits, which include components engineered to work together. If you want to raise your rig and retain your stock springs, we have adjustable spacers that allow ride height to be raised 2-4”.

    Coil, Leaf, & Torsion Bar | Describing The 3 Different Kinds of Springs
    The springs in your vehicle probably aren't something you think about until there's a problem or you've decided to upgrade suspension parts in the interest of sportier handling. But what specifically do springs do? In short, they play a major role in the safe handling and ride comfort of your vehicle. Not only do they keep a vehicle at a designated standing height, they provide recoil necessary to bounce back after suspension components move up and down over uneven road surfaces. By themselves, springs will continue to bounce up and down for a long time unless a motion damper such as a shock absorber is present to keep things stable. Springs can be soft and extremely bouncy, or they can be stiffer and less bounce-prone.

    How to Inspect Your Suspension System
    The very first thing to know about timely suspension system diagnosis is that the stability and steering control of your vehicle and, what is more important, your safety on the road depends on how often you make it. Automotive suspension belongs to one of those car systems that are constantly exposed to high loads and thus are prone to wear and tear. Most specialists recommend inspecting suspension system after every 6,500-7,500 miles or when there are any signs of its breakage.

    How Low Can You Go?
    Lowering is high on the list of many people who want to improve the appearance of their car. If you want to lower your car with the coil springs, then replacing them with lowering springs is the way to go. But what if you want to lower your car and also make it handle better? If that’s your goal then consider coil-over shocks.
