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 rate.  
Every AFCO Coil 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.
