Update
Hey all,
I finally had the time to mess with the Tahoe some last night. I jacked the truck up, pulled the autoride links, and pulled the Belltech bump stops. I cut the links to 2" (that's WITHOUT the caps -- so, I think that WITH the caps I'm @ 2-1/2" in total), and cut the bump stops (I'd say I cut 1/4" off the stops).
I've only driven a mile or so in this trim, but, man, what a difference. The compressor finally DIDN'T kick on in my driveway this morning, so the short ride to work was at the sitting, uninflated ride height. Now, the shocks actually feel like they're working properly, absorbing bumps, and smoothing out the ride.
I have to drive into Philly (where the streets are miserable) today, so that will be the ultimate test of the set up. But, man, it's so different already.
Assuming that these tweaks keep additional air out of the shocks and keep the bump stops further away from making contact, this will be the set up that I've always wanted. Assuming the ride doesn't change from here, I can say that this set up rides much better than stock.
