How coil springs put a spring in the step of your drive.
Coil springs, also known as suspension springs, are the key component of your vehicle which contributes to reducing the excessive up and down movement caused by your drive. These springs support the vehicle and absorb the bumps and shocks, especially off road.
Where to find your coil springs & what to do with them.
Depending on your vehicle's configuration, your springs will be located either between the axle and the chassis, or between the control arm and the chassis. Your springs should be maintained in excellent working order, or you'll pay the price through an inferior ride and huge expense.
Some things to think about when selecting the right suspension spring:
Type of Spring
There are two primary designs of suspension springs on the market, helical springs and progressively-wound springs. Get to know the differences and specific benefits.
Helical Springs
Helical springs wires are shaped into a helix and used for tensile loads. These springs are simply to fit and come in numerous varied dimensions.
Progressively-wound Springs
Progressively-wound springs are a step up from helical springs, used for off-road modes as the coil pitch gets tighter when it gets to the maximum assistance in handling, traction and control.
Spring Material
Top of the range coil springs should consist of chrome-silicone or chrome-vanadium. Coil springs should also be mandrel-bent and the bigger diameter tolerances are a smart choice.
TOP SPRING TIP!
There are many great quality suspension springs to choose from, but you should also choose carefully when it comes to the supplier… make sure you talk to certified technicians and that free installation comes with purchase.
