Using a suspension lift component box may be quite difficult, but it's worth the effort when you see your truck's new look. Modify your truck's suspension system to get an increase of 4 to 6 inches to its height. Since this project involves working with very vital parts of the vehicle, it is advisable to ask help from a professional if you have any doubts on the procedure. Read this overview guide to give you a jumpstart before you start the modification.
Difficulty level: Difficult
- Wheel chocks
- Floor jack
- Jack stands
- Socket set
- Wrench set
- Measuring tape
- Suspension lift component box
Step 1: Park your car on a flat and well lit area for the installation. Engage the parking brake and put wheel chocks on the rear wheels. Raise the truck with a floor jack and secure it with jack stands. Make sure you place the stand behind the front spring shackles.
Step 2: Remove the front tires. With the suspension exposed, remove the shocks, u-bolts, and the main suspension assembly. Depending on the model, this can either be coil springs, struts, or leaf springs. For some models, it may be necessary to remove other parts such as the ABS line, tie rod, anti sway bar, torsion bar, and other specific parts.
Step 3: Install the new main suspension assembly from the kit. Put the other new parts with the kit such as u-bolts, studs, bars, and struts. For leaf springs, don't fully tighten yet. This will be done before lowering the car.
Step 4: Return the front tires. If your truck has one, adjust the turning radius block to see that the wheel's inner face is not in contact with any part.
Step 5: Check the clearance of the whole assembly with your measuring tape. Once you are sure that everything is at a good distance between each other, tighten all the parts according to specification.
Step 6: Lower the front of the car to finish.
Step 7: For the rear end of the truck, the steps for installation are similar to the steps for the front. It may change depending on your vehicles rear suspension system, if it has any attachments, and the lift component box you will install.
This installation will take between 2 to 4 hours.
- Be careful during disassembly of the suspension. Since this part carries a heavy load, it may suddenly fall and drop. Make sure everything is checked and supported before completely removing anything.
- The set is designed to work altogether. Use only the parts supplied by the kit. Don't make changes to increase height or just because you think it's better that way.
