2007 GMC Sierra Air Bag Suspension - Lay Out a Late Model

From the Driver Seat
This install wasn't for the faint of heart. Experienced builders and truck owners should be confident before going out and cutting up a truck. That said, Jared had a good plan before beginning the truck's buildup and executed it very well. The overall package proved to be a good one, as the truck rides nicely and lays hard enough to put the frame on the ground. One of the nicest features of this install was our introduction to the Easy Street Auto Pilot air controller. This setup worked very well and allowed us to push one button for ride height, slammed, and all the way up. The wiring was easy and only one wire was run inside the cab, which made the installation even easier. Digital accuracy was appreciated on the read-out and the unit looked stylish, complementing the interior. Also with the sturdy four-link and large Slam 'bags, the Fullmer family can tow with the GMC. Not bad for a weekend spent in the garage.

Jared was ready to bolt in the Slam Specialties RE8 airbags and run the 1/2-inch DOT air line.	It was imperative to keep the air line away from heat and moving parts, so these clamps with self-tapping screws were used to keep the air lines secured.
Using a jack to lift the gas tank, it was carefully lifted into placed and all of the wiring and fuel lines were reconnected.	The bed was tilted on its end and the wheelwells were cut out to clear the large, 24-inch Rushforth wheels and Toyo Tire tires. The center section was cut out to accommodate the AVS 'bag mounts and crossmember.
Before the bed was placed onto the frame, check out how the rear suspension and airbag parts looked all finished up.	With some help, the bed was slid over the wheels and tires, then bolted onto the frame.
Moving up front, the brake calipers, rotors, spindles, and coilover were all removed.	Providing an instant 2-inch drop, the Belltech spindles replaced the factory units.
Using the upper 'bag mount supplied by AVS, Jared fabbed up three pieces of 1-inch tubing, which provided the additional space for the airbag drop. This placed the airbag in a better position and helped lower the truck even more.	The plasma cutter was again brought out to notch the frame where the lower control arm mounts were. This allowed the lower control arm more travel to help the truck lay out.
Jared again used his fabrication skills by welding a single piece of tubing to the lower 'bag plate. He fabbed up this piece, which allowed the lower 'bag mount to bolt into the factory location on the lower control arm. The front suspension was then reassembled.	Excitement filled the garage after 3-1/2 days of hard work, they were finally ready to lay the truck out using the Easy Street Auto Pilot installed in the cab.
After a weekend's worth of wrenching, it was laid out and looking good.	Here, you can see how the profile looks with 22s front and rear.

Tools needed: Welder, plasma cutter, Sawzall, straight edge, Swanson magnetic angle finder, measuring tape, metric handtools, jackstands, hoist, and a couple of buddies
