Hyperco's 2-1/2" I.D. chrome silicon wire coil-over springs bring NASCAR technology to your car. These ultra lightweight springs have accurate, consistent rates and carry a lifetime manufacturers warranty. The blue epoxy powder coating is applied thin, yet it is flexible unlike competitors plastic coatings which can build up over time, possibly changing the overall spring rate.
Available in a variety of rates.

The AFCOIL XCS Series barrel springs are designed to eliminate the common problem of interference between the spring and the shock body. Increasing the diameter of the active coils has reduced both the slenderness ratio (spring length vs. diameter) and the potential stress levels of XCS springs compared to standard diameter coil-over springs. 
As a result, XCS springs will not buckle under load and will provide more shock clearance than standard diameter coil-over springs. XCS series springs require no special mounting hardware and, in most cases, weigh the same or less than standard coil-over springs. 
All AFCOILS carry a lifetime warranty to remain within 2% of the original nominal free height.

There's a lot riding on your springs-literally. Springs are your car's connection to the ground, and their performance is directly related to all other suspension components. Inconsistent, weak springs can cause a multitude of handling problems, and in some cases, dangerous situations. When it comes to choosing coil springs there are many alternatives, but if you want the best you can get, the choice is clear: choose Afcoils. 
All Afcoils carry a lifetime warranty to remain within 2% of the original nominal free height. Choose your length and rate.  
Machine-ground on both ends to tolerances within 1 degree
Pressed to solid height and "pre-set" - eliminates potential for additional set 
Optimized material thickness and coil spacing
Made of super-high tensile strength chrome silicon wire for long life and and a consistent rate
All  springs are cold wound on the latest automated coiling equipment and  heat treated twice during manufacturing to be able to withstand even the  most abusive conditions 
To further enhance durability, Afcoils are shot-peened and coated with a durable yellow finish
