Anyone using these rear spring helper bags.
Looks like Firestone makes them. Are there others? What did you pay? Found them for $90 at SD Truck Springs.

How hard are they to install? One man job or need a helper? Did you mount the air valve somewhere permanent? Where? Did you make a T so you only have 1 valve for both sides or keep 2 separate valves? Is there a reason? What else do I need to know?
How well are they working?
