Im looking to dropp my truck 2/3. I have 26's on it right now and was offered a Sprint performance drop kit for it. I called the company but they say it wont work cause of the air adjustable rear shocks. Can i install the springs and slap on a pair of r shock relocators from djm? Thanks guys

The shock extenders are a great addition - I definitely recommend them - but the other thing you'll need is new (shorter) sensor rods for the Autoride system. Without them, the sensors will think that your truck is sitting too low and will add air to the shocks to compensate.

Belltech and McGaughy offer them, but I'm not sure they sell them individually. The thing is, they're generally tailored to a specific spring. I wouldn't recommend touching your stock ones, but if you strike out with the manufacturers above, lots of SUV folks have gone to machine shops (or even good hardware stores) to have shorter rods of the same diameter made for them.
Along those lines, and I'm not trying to sway you if you're set on Sprint, but I just can't recommend Belltech parts highly enough...especially their rear springs, which are designed to help maintain a semblance of ride quality while also handling weight very well. Check out the progression on my stock vs. Belltech 2" rear springs:

Granted, I haven't seen Sprint's springs, but I'd take a guess that they didn't put that kind of effort into the design. I can tell you that I've also had Eibach and McGaughy's rear springs over the years...and the ride quality was miserable by comparison.
Anyway, sorry for the tangent. What's your solution up front - springs or spindles? If you go with a 2" drop via springs, make sure the kit includes shims so you can keep the alignment within spec.
