5" x 11" Rear Coil Springs

The AFCOIL yellow coating is recognized for quality and dependable performance. AFCOILS are the industry leader in quality, design and performance. No spring line is more recognizable. Across the industry, more racers rely on AFCOILS than any other brand of spring.

As a leading manufacturer in valve springs, PAC Racing Springs is able to use the latest in extreme high tensile alloy used in valve springs for use in suspension springs. The high tensile valve spring alloy allows mass reduction, enhanced fatigue life, and very high travel length. We address the fatigue life (failures) by adding heat treating and the latest in shot peening.

Most notably, the Eibach Springmeisters, working at production plants in Germany and the USA: Talented, expert craftsmen, each committed to creating the finest race springs in the world.

Hyperco's never ending pursuit of Performance has lead to yet another breakthrough in Conventional Motorsports spring design -- the "Dynamic Travel Response" enhancement! Our engineers analyzed the dynamic characteristics that are essential to Conventional Spring performance and utilized this data to develop the Dynamic Travel Response design concept. Our conventional springs are engineered to exceed the dynamic performance requirements for travel and rate linearity placed on them in the race car. Another result of the DTR concept is a significant reduction in the physical weight of each spring. As spring travel and total load requirements are part of the Dynamic Travel design criteria, Hyperco was able to reduce the weight and improve the performance of our entire Conventional Spring line without compromising consistency and durability. The results are in...Hyperco's Dynamic Travel Response enhancement is a winner at every level (dirt & pavement).

Since 1986 Suspension Spring Specialist, Inc. has been designing and manufacturing coil springs for the automotive racing industry. They have one of the largest selections of heights and rates of springs available, and a large inventory of springs for fast, same day shipment, as well as various size of pro shocks and assorted accesories you may need.

Landrum Gold Coil-Over Springs are made of the highest grade of Chrome Silicon wire found worldwide. Cold wound, not hot wound. Each Landrum Gold coil-over spring is properly heat treated and stress relieved to insure the sides of spring remain parallel during installation. We feature Landrum Gold Coil-Over Springs at low everyday prices.

Swift Springs Coil-Over Barrel Standard Race Springs are constructed of H5S.TW, motorsport's most advanced spring material. Swift made a name for itself on the tracks of Asia, Europe, and U.S. by defying all accepted concepts and speculations about the future, if any, in coil spring science. When many other company were looking at expensive and brittle titanium composites to create the next evolution of springs, Swift Springs was looking at reinventing the entire science of coil spring dynamics. Swift saw that most others are using the old regular silicone chrome material, which was not strong enough. It used a heat tempering method that damaged the strength of the material that requiring more coils, in turn, more weight. The material was also suffering from a short life span. With springs like this leading the industries, Swift Springs saw room for improvement. Swift Springs R & D team created material, called H5S.TW which is stronger then regular silicone chrome material. Because of this material, Swift Springs could make the spring wire thinner, and could wind the springs with fewer coils, which greatly decreased weight while dramatically increasing available stroke. Barrel Design: Isn't the barrel design heavier? Not on Swift. Still one of the lightest!! All of Swift Standard 10 and longer Coil over springs are barrel design; the design is to solve all spring bowing problems. With bowing springs, you can expect spring rate inconsistency, and rubbing against shock body that would lead to damages on the shock adjusting perch thread. Unlike others, Swift designed barrel springs with one common rule, which is all the barrel springs design have a maximum of 4 OD. Barrel designed springs tend to be heavier in weight than straight shape springs, but due to their advanced technology Swift coil springs will never have this problem.

We feature Swift Springs Coil-Over Barrel Standard Race Springs at low everyday prices.

Integra uses an exclusive VMX Alloy not found in other racing springs. This allows Integra MX springs to be manufactured up to 30% lighter and have up to 30% more stroke, yielding up to 1. 25" more travel before coil bind than other springs. This gives you a lighter, more linear spring, with added travel before coil bind. All Integra springs are guaranteed to remain within 1% square and 2% of free height for the life of the spring!
