Here at Andy's Auto Sport we carry a full range of GMC Sierra coil springs to replace your tired old setup. Whether you want to lift, lower or maintain your stock ride height, you are sure to find the perfect GMC Sierra coil springs for your application in our extensive lineup.

The first patent for a coil spring was issued in the 1700s. However the spring design did not gain popularity in the automotive world until the mid-1930s. Since then coil springs have been standard on many leading luxury and sports cars thanks to their compact and light design, and great ride and handling characteristics. Aftermarket GMC Sierra coil springs come in an infinite amount spring rates including progressive rate springs which increase in stiffness as they compress to give a great ride and stellar handling. If you are looking for the perfect way to give your vehicle added performance and the right look, it is hard to top a new set of coil springs.

Q: How do you install coil springs?
A: We recommend taking your truck to a professional shop for installation because removing the compressed shock can prove dangerous. Coil springs are installed by removing the factory springs and shocks from their perch, installing the new coil springs and re-installing the shocks.

Q: Do coil springs come in sets of 4?
A: Coil springs are sold on our site in sets of two unless otherwise noted. Spring companies sell these springs in sets of two for the front (and two for the rear when applicable, depending on your truck or SUV).

Q: What are coil springs? Why buy coil springs?
A: Coil springs are one way to lower the front end (and in some cases the rear) of your truck or SUV. Many trucks have factory coil springs as part of the suspension for the front of the truck, and these can be replaced with coil springs engineered to lower your truck. You can lower the front of your truck in multiple ways; using lowering coil springs is just one of them. Coil springs are popular because they are, in general, less expensive than other means of lowering the front of your truck. Most coil springs can be used with either your factory spindles or aftermarket lowering spindles.

Q: Are coil springs adjustable?
A: Coil springs are non-adjustable and have pre-set height and spring rates. Make sure you choose the right drop for your truck the first time, because otherwise you will need to purchase a new set if you have a change of heart.
