Hey TW, this is my first post. I have a 07 DCLB TRD Sport 2wd and I'm putting Billy's on all four, with the front at 1.75. I tow a 5000# trailer on occasion and was planning on a Wheelers 1.5 AAL. I don't have the rear TSB, and don't want to be nose high. Can I install Firestone ride right 2047 air bags instead of the AAL, to level the ride, or would I need both the AAL and air bags?Also, are the standard rear 5100's recommend with this set up?
Any help would be greatly appreciated.
