Good discussions here.

On the driveshaft comment, I took our 80-series across the Con with the WWOR arms and our shaft was in great condition at the end. One is always conscious of the rear diff placement anyway and it's a priority to avoid contact, as it is a sure detriment to progress if hung on a rock, not to mention yoke, driveshaft or even major pumpkin damage.

On the clearance being "minimal"--not at all, we're actually talking a minimum of 3 1/2 inches of additional clearance. I just went out and measured and the high point of the WWOR bar is approximately 14 1/2 inches off the ground at its curve point. I'd LOVE to have 3 1/2 more inches of clearance under my Cruiser as a whole (heck, who wouldn't?), but without upgrading our 35" tires to 39's it's kinda hard. But 3.5 inches (minimum) of additional clearance is pretty substantial in the wheeling world.

Point in fact: look at the clockable transfer case adapters Marlin sells. You gain 1 3/16" clearance with it. Marlin's rotated crossmember gets you 3" inches more clearance. Clearance is the name of the wheeling game--or at least a major part of it--and many parts are made just for this reason.

I just don't see the point in hanging up on ANY rock. Any impact hurts progress.
