Firestone Coil-Rite Air Spring Basics

Firestone Coil-Rite springs fit inside your existing rear coil springs to maximize the effectiveness of your suspension system. The added cushion provided by the air springs allows your Cadillac Escalade to better handle a heavy load or trailer. Hauling heavy loads or towing a heavy trailer can make the rear of your Cadillac Escalade sag and the front end rise. This puts more strain on your rear axle and reduces contact between your front tires and the road, causing problems with braking, steering control and traction. By adding air springs to your rear suspension, you can help to level your Cadillac Escalade for more effective braking and handling under heavy loading or when you encounter adverse road conditions. The air springs also help to level your headlight beams and reduce wear on your tires.

Adjustable Air Pressure

The air pressure in your Coil-Rite springs can be adjusted manually, side to side, to compensate for off-center loads. A centered load improves the stability of your Cadillac Escalade by reducing body roll. The air springs will also help to absorb road shock and soften contact between your axle and frame. This prevents bottoming out, thus improving ride comfort. Route the air line tubing for the springs to your Cadillac Escalade's bumper to provide easy access to the manual inflation valves.

The air bagsy fit nicely into the coil springs so there are really no modifications needed to install them. The exhaust shields are easily shaped to fit onto the tail pipe where it wraps over the axle. The only hic- up I had was the installation instructions did not include a diagram of the hose routing for my vehicle, which tells you to mount the bags with air line out the top or out the bottom. I found there was more room out the top and a shorter route for the air lines to be ran. 63562


Tim, Firestone does not include instructions on howwhere to run the lines as so many people want or need to locate them differently, even on the same vehicle.Some like the fittings mounted through the bumper for easy access, others like them hidden underneath, and others still need to run them forward to a remotely controlled air compressor under the vehicle.

The directions are set up to cover a wide variety of vehicles. There are pages inserted for adjustments to the instructions for a smaller group of vehicles closely related to mine. I still found them confusing and not very clear. Once I got past trying to do exactly what the instructions (or at least the pictures) were saying, I was able to just look at my setup and install the air springs. The picture for the inserted heat shield instructions was the most confusing because it shows the air hose on the top but for my Avalanche (and I believe most late GM SUVs) the air hose is on the bottom. On the positive side the product appears to be of strong construction for the springs, hose, and the fittings. I'm confident it will greatly improve my Avalanche's ability to tow my trailer safely61590
