Has anyone had this problem and were you able to solve it? According to Reese it will void the warranty if I drill a hole for the new Air Bag installation.
All of this is making me look to another way to solve the problem. Has anyone had any experience with Super Springs?
I have almost exact same setup except I have the Curt brackets and ISR's. On drivers side the upper air bag mount uses the aft DEF tank mount bracket bolt hole which is behind the Curt bracket. I had to remove the Curt bracket from drivers side to get to factory bolt, removed bolt and p-clip and used bolt & nut supplied with airbag kit to attach upper airbag bracket and DEF bracket then reinstalled Curt bracket. On passenger side the upper airbag attach hole is thru the large oval shaped hole in middle of bracket, I just removed 3/4" bolt I installed during Curt bracket install and added the upper airbag bracket in, bolt was plenty long.
Airbags made a huge difference. I would also recommend onboard air pump, I installed as well, slight PITA but once done it works great! And also I could not imagine arriving at CG, dumping the 5thW off and then spending the next few days riding around with 40 PSI of air in the bags with no load.. ouch! LOL .
BTW, The Curt bracket is a no drill kit at <$100 too. It is a solid piece of kit,made in The USA and your rails would work with it too.
