Rear springs

[f419sr1]

I like the air bags. I used them on my other truck. The work well and you can adjust the ride. If you want to do springs. Look up a spring place around you. Its not that expensive to have your springs rebuilt and add a few. The spring place will also be able the tell you how many to add to match up to what your hauling.

I had the springs re-arched on a Chev 3/4; Too stiff unloaded. Next truck, I tried firestone airbags; Solved the heavy load sag problem. The airbags made the unloaded ride better than original. I adjusted pressure manually with two fittings near the rear license plate.
