    Theres a lot riding on your springs-literally. Springs are your cars 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. The 1-7/8" I.D. springs are perfect for open wheel, dwarf cars, as well as other applications with small body shocks.

    • Every AFCO Coil-Over Spring is machine-ground on both ends to tolerances within 1 degree, and then pressed to solid height and "pre-set." This process virtually eliminates any potential for additional set.
    • AFCO has made a science of optimizing the variables of material thickness and coil spacing to achieve the best possible design for each rate and height of spring in their product line.
    • AFCOILS® incorporate the use 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.
