Coil, Suspension, and Lowering Springs

While they were once found primarily in passenger cars, coil springs are now common on most vehicles on the road today, including trucks and SUVs. That’s probably because a coil spring suspension offers a few key advantages over a leaf spring setup, namely in the areas of range of movement, adjustability, and size.

And coil springs can offer a lot of flexibility (pun intended) for aftermarket suspension modifications too, thanks to things like coil spring isolators, spacers, braces, helpers, and more. Coil spring lift kits and lowering kits are quite common and installation often means swapping out the OE coil spring for a replacement coil spring. It should be noted that installing coil springs can require the use of a specialized spring compressor tool.

Coil spring suspensions have been around for decades, particularly in performance applications. As coil spring adoption grew, coils springs first appeared in the front suspension of the vehicle, then eventually the rear. As mentioned above, most light duty vehicles on the road nowadays feature a coil spring suspension front and rear.

Yet coil springs weren’t often seen in truck applications, at least in the rear. But as coil spring technology develops, more and more trucks are using heavy duty coil springs in the rear suspension as well. So, it’s common now to have heavy duty coil spring lift kits for trucks and SUVs. In fact, coil spring spacers have given truck and SUV owners an easy way to add a few vital inches of lift to their coil spring-equipped vehicle.
