TeraFlex 2.5″ Budget Boost Lift Kit for Wrangler JK – Part 2

As usual before beginning any project make sure you have the tools and capability to safely perform the tasks. Read all directions and follow safe garage habits, use jack stands and proper safety wear. We followed the directions from TeraFlex, we also added some tips and steps along the way, they will be marked with a the word TIP.

Some tools required

jack jack stands metric sockets ratchets metric wrenches
pry bar blocks of wood grease lug wrench

After properly jacking up the Jeep remove the tires. Remove the upper shock nut. TIP: Disconnect the front sway bar at the axle bolt (see below) this will allow greater movement of the axle. Be careful not to over stretch the brake and/or the anti-lock wiring. Lower the axle and remove the front springs.

Spring Removed

With the springs removed remove the bump stop from the cup by rocking it back and forth. Remove the upper spring isolator. Install the TeraFlex front spacer, then the isolator. Install the TeraFlex bump stop extension. TIP: Put a little grease on the spacer and position it into the cup. Using a block of wood and the jack carefully press the spacer into the cup. Install the bump stop into the spacer.

Now reinstall the coil spring. TIP: A coil spring compressor may make the job easier here. You will need to muscle the spring onto the perch here. A strong pry bar and a few blocks of wood can make it go a little easier. Install the shock adapter onto the top of the shocks.

Install the bushings and raise the axle to install the shock nut. TIP: Make sure you note the proper installation of the shock bushing. See image on the right. After all the components are reinstalled reattach the front sway bar and put on the wheels. Lower the Jeep and check.
