A Practical Guide: Installing a Helper Spring Mounting Kit
Does your car become ominously jumpy particularly while you're driving through a patchy terrain? This is possibly due to the extra cargo in your car. If you'll be putting heavy cargo on your car, you should mount a helper spring that will enable your car's axle to cart greater cargo. To set up a helper spring faster and easier, you need to have a helper spring mounting kit. This mounting kit contains u-bolts, brackets, and other parts that are necessary for the installation of a helper spring. Below is a do-it-yourself guide for installing a helper spring mounting kit:
Difficulty level: Moderate
Things you'll need:
- Helper spring mounting kit
- Wheel chocks
- Car jack
- Jack stands
- Torque wrench
- Axle strap
- Pair of carriage bolts
- One of the three: Razor blade, hose cutter, or sharp knife
- 5/16-inch drill bit
Step 1: Read the instructions in your helper spring mounting kit carefully. Each make model may have different installation instructions and tool requirements. As safety precautions, put wheel chocks on your car's wheels, and use jack stands that can hold up under your car's weight. Also, be sure to disconnect the negative battery cable.
Step 2: Assemble the brackets on the helper springs. The brackets have holes that are marked “L” for left and “R” for right. For the driver side of your car, fasten the helper springs to the bracket through the holes marked “L”. Do the same procedure for the passenger side using the holes marked “R”.
Step 3: Use a torque wrench on the bracket nuts, but be sure to inspect the mounting bolt clearances first.
Step 4: Detach the factory jounce bumpers. Once you've taken them out, set up the air spring unit between the frame rail and the axle tube. You may need to manually compress the air spring unit a bit to make it more secure. The new helper springs will carry out the tasks of the bumpers.
Step 5: Set the lower air spring bracket into place using the factory U-bolts. On the other hand, use a U-bolt included in the helper spring mounting kit to keep the air spring from horizontal movement. The U-bolt encloses around the factory leaf spring perch.
Step 6: Using an axle strap and a pair of carriage bolts, fasten the helper springs to the axle tube. Then, check if the helper springs are tightly in place. If they are, you've successfully finished mounting them.
Step 7: Decide on where you want the air line to transverse. Then, snip it appropriately using a razor blade, hose cutter, or a sharp knife, and insert it to the push-lock fittings. To protect the air line from damage, use the zip ties included in the helper spring mounting kit.
Step 8: Install Schrader valves, which separately give air pressure to each of the helper springs, by using a 5/16-inch drill bit.
Carrying out this whole installation process will only take less than two hours of your time, as well as just some basic repair tools.
