Coilover Overview

CoilOver Tech

A coilover is simply a shock surrounded by a coil spring; it places the shock and coil in one linear unit. A coilover is a simple solution for most suspension designs, but can often be difficult to understand what you need. Fortunately, RideTech has your back with 14 years of suspension development.

Choosing a coilover begins with two important decisions. The first is choosing the function of your vehicle. If you are building a performance car, then you will want a coilover that has an adjustable shock. This allows the driver to tweak the “stiffness” of the suspension with a twist of a knob located on the shock. This adjustment knob controls the shock valving which controls the damping of the coilover. This is a huge benefit for drivers who want to fine tune their performance for the track, autocross, or the road. However, if you are building a cruiser, a non-adjustable shock is a much more economical solution. The RideTech non-adjustable shock is preset to give a soft valve setting which allows the best ride quality possible, leaving the guess work out.

The second most important decision in choosing a coilover is finding your desired spring-rate for the coil spring. Spring rate is the force required to compress a spring 1″ and is an important factor in how comfortable your car rides and your ride height. Finding the desired spring rate is a bit tricky, since you will have to know a little more about the design of your suspension. To help guide you through this process, RideTech has developed a simple spring-rate calculator:

The Shock

RideTech’s engineering team started from the ground up with all new impact forged aluminum shock body.
Before selecting a shock, the first thing you will need to consider is whether you are looking for performance or ride quality. If the latter, the non-adjustable shock should be your economical choice.
