Lower Your Car
by LSC Tech Board

WARNING: Your airbags must be in good condition before you perform this modification. Old airbags tend to crack with age, lowering the car will disturb the airbag creases, leading to an air leak. How do you know what condition your bags are in? Do not lower the car if: your car has over 100,000 miles with the original bags, or if your car sags ANY after sitting for a period of time. If you are in doubt as to the condition of your airbags and do not have the ability (or money) to replace your airbags within a few weeks, DO NOT LOWER YOUR CAR! I have learned this the hard way so that you won't have to. But thats just my opinion, I could be wrong (but I'm not).


Now on to the info.....

One interesting use of the Air Ride Suspension is that it can be used to lower your car. This will help the looks as well as the handling of the car. Make sure to turn off the Air Ride Suspension. First you need to remove the front tires (the car should be on JACK STANDS, never trust a jack, bricks, etc...). You will notice a small, shock absorber looking thing connected to the lower A-arm. This is the ride height sensor. It is a attached to the A-arm by an adjustable bracket. Unbolt the sensor's bottom bolt and move it to the top hole in the bracket. This will fool the sensor into thinking the car is sitting too high. The computer will let some air out of the bag and down comes the car (about an inch). Do both side at the same time and then put the tires back on. Turn the Air Ride Suspension back on and crank the car. Check to make sure the car is sitting level side-to-side. If not, you may have moved the sensor the wrong way in the bracket. Now you car has that "raked" look like a real hot rod. To complete the look you need to lower the back. The amount you lower it is personal taste. The ride height sensor is located near the center of the rear axle. You will need to place the car on jack stands for sure for this. It is best to place the jack stands under the frame instead of the axle. This lets the axle drop and gives you room to work. The sensor is the same as the ones up front but it is mounted different. Remove the actual bracket from the bolts on the frame and move it down. The bracket will now be attached by one bolt instead of two. Rotate the bracket until the sensor is slightly stretched more than it's stock position. Lower the car (but keep the jack underneath it), turn on the Air Ride Suspension and crank the car. If you are lucky the car will drop the rear end about an inch and stop. If you moved the bracket too far, the car will drop to the ground. This is why you kept the jack under the car. Readjust the bracket until you get just the right height. This may take a while to be patient. When you reach the height you want, make sure you really crank down on the bolt holding the sensor bracket. Now for the most important part: ALIGN THE CAR!! Any auto shop worth a darn should have no problem aligning your car. Now your car will look better (blech...fender gap is ugly), and ride just as good as before. Enjoy!
