Hey, y'all. If you recall, I did a SOA on my 94 YH and some fender trimming to fit my 37" SuperSwamper SSRs (37x10.5 on 10 Black Rock Crawlers, 5 on 5.5").
With Teraflex/Revolver folding shackles front and back, I was getting a bit over 10 inches of articulation on each rear wheel. However, 3" of that was compression, and 7" was extension.
I hadn't yet installed bumpstops, so I was finding I was bottoming out pretty hard. The cheap, easy thing would have been to simply install some bumpstops. But that wouldn't have addressed my compression/extension imbalance.
So I finished today prototyping an Air Spring system (for the left rear, anyway). So far, it gives me a full 4.5" of active lift. That's 4.5" I can use to "cush" or stiffen my ride, for off-camber correction, or for giving a little more compression travel.
The key was to let it act passively when I don't want to use it, so it just acts as a soft bump stop, and allow the components to articulate as much as they can without restriction. It's basically got a 1/2-13 bolt (12" long) that sticks up through the frame (yes, drilled 5/8" hole through the frame) and telescopes inside a guide tube there. A 3/8 steel plate sits atop the ubolts, and the air spring attaches to the plate.
The plan is to dupe the right rear, then prototype the front with a similar set-up. Then have individual, 4 corner solenoid valve control. I think I'm going to need a second tank to augment the locker air tank.
I'll post pics and/or vid SOON!
