Installing lowering springs on a vehicle is a very simple modification that will both enhance the appearance of the car and improve handling. Lowering springs are very simple to install at home. All that is needed is a jack, a hacksaw, a pair of jack stands, and a good socket set.
The installation itself is rather simple. This article will walk through first the rear spring installation, then the front.
For the rear:
- Jack up the rear of the vehicle and set on jack stands. Then remove both rear wheels.
- In the car manual, locate the position of the shock nut and bolt. Remove these from both sides of the car. This will let the suspension drop and give access to the springs.
- With the bolts removed, the springs should come out easily by hand. If there is trouble in this step, press down on the rear axle to loosen the springs.
- Install any tape wraps or dampers that may have come with the lowering springs by following included instructions. Place the new lowering springs right side up in the location of the old springs.
- Lift the rear axle up until the shock nut and bolt can be replaced, and replace them.
The rear spring installation is now complete, and the rear wheels can be replaced and the car lowered from the jack stands.
Now the front springs need to be installed:
- Jack up the front of the car and set on stands. Remove both of the front wheels.
- Look in the car manual for the locations of the front strut bolts, the brake bolt, and the front sway bar end links. These all need to be removed.
- Next, the upper strut assemblies must be removed. Again, look in the cat manual on how to do this, as it varies greatly from car to car. Generally, this will be done from the hood of the car rather than from the bottom. Remove the entire strut assembly. There is one strut assembly for each side of the car.
- Compress the spring, which is around the strut, and remove the hat and bump stop from the strut. Then, remove the spring from the strut. Do this for both struts.
- Place the new spring around the strut, where the old spring was. Again, for both sides.
- Now take each bump stop and shorten them as required by your new spring size by cutting them with a hack saw. Make sure the cut is as straight as possible. Occasionally, shortened bump stops will be included with springs.
- Reassemble your strut assembly and reinstall it on your car by reversing steps 4 and 3.
- Replace wheels, and installation is complete!
