FYI for people looking into doing this, airlift has a special til the end of february for rebates on their products.
Air Spring Air Suspension | Air Lift Company - Tow and Haul with Safety and Comfort
I order this kit to go with my bags, $140 for a complete compressor kit aint bad imo
Air Lift 25850 Load Controller Single Standard Duty Compressor : Amazon.com : Automotive

 

After having lived with Air Lift’s #59565 bags for thousands of miles and dozens of payloads, I couldn’t be more pleased.

Their dramatic contribution to control simply must be experienced firsthand if you work your truck. Highly recommended.

 

bumping this up, airlift just started there $50 rebate again.

4wheelonline.com has them 25% off and free shipping right now also.

 

I couldn't be happier with my AirLift gauge/switch setup.

 

Hmm anybody make a kit for nnbs with a 7" flip kit. Ive seen some but require a c notch as the bag bracket bolts on to the notch bolts. I use my truck to haul crap, mostly trannys and shortblocks and it doesnt like it. I only have like 2" between the axle and frame and ive heard em kissing a couple of times.
