I've been talking with Air Ride for months now about it and they came out with a new one recently that bolts right into the A-body alterktion. It's a little shorter than the current coil-over I'm using, so the ride height is a little lower. But, at the correct height for the shock, it's right where I like it. The cross bar on the frame is about 4" off the ground. And with a 26" tire, I can lower it 3" from there - too low obviously to drive, but it looks neat sitting there that low. I didn't bottom out anywhere around here(which is really saying something), but I'm going to change my oil pan anyway since it's just a street car. But lowering isn't my reason for it...
What REALLY has me excited about it is the ride quality - it's absolutely smooth as glass. I'm totally amazed how nice the car drives with them - that's what prompted me to do the a-body rear - I have to have it in my own car. Initially I thought air ride was just a bunch of bling, but I'm sold on the stuff. I never thought my Dart would ride this nice and still handle.
As for retrofitting, anyone with an A-body alterktion that has the 10-14" travel shocks can use them. Older systems that had the short shocks don't have enough room.
Also, the B and E body systems need a little modifying so none of them can be retro-fit. Well, they need longer a-arms to widen the track a little to make room, the frame would be the same. Still an added cost though, so I'm not counting on many people changing over.
Soooo, I'm now a dealer for Air Ride. We'll have the alterktion's with an air ride option, the bolt in B and E rear air 4-bars, and I'll be doing the rear air 4-bar for the a-bodies. The A-body rear shocks may have clearance issues with the gas tank, but I have more work to do yet, so I'm not sure at this point...
I'd put some pictures up, but I have my car all torn apart.........AGAIN. I just can't keep this thing together for more than 3 months at a time. LOL
