What is the benefit of using coil-overs?

Coil-overs let you adjust the ride height of your vehicle. You can fine-tune the suspension for the street or track. Plus, you can adjust the damping to match your driving style.

What tools are needed for installation?

Since this is a bolt-in kit, you'll need basic hand tools like wrenches and sockets. Refer to the manufacturer's installation instructions for specific tool requirements and torque specs.

How do I adjust the ride height?

The ride height is adjusted by threading the spring perch up or down on the shock body. This compresses or decompresses the spring, changing the ride height. Refer to the manufacturer's instructions for the proper procedure.
