MDethloff,
There is another member who put 37's on his stock PW rims and no lift and they did rub on the sway bar. He actually ground some off it looks from his pictures to clear it.
What I posted above from Carli and CJC is from what they have found in their testing. Seems CJC does a lot of testing and real world driving of the systems, so I'd say they have a good working knowledge of what works and what doesn't.
And I've run 2.5" remote resi King shocks on a K5 I built with Deaver springs. 12/18" of wheel travel. So I know how well the systems can work when setup/tuned correctly.
My problem is I don't really want to lift my truck anymore as I use it as a truck. But I'd like to try and find some better shocks to help with the ride.
As far as putting in a bed slider as mentioned before, it will not work for my usage. When I'm doing race support, I carry anything from 40" race tires/rims, 110G axillary fuel tanks, 55G drums of race fuel, or 110G pressure probe for refueling the race truck. So putting one of the bed slide boxes in, I'm not sure it would handle the weight on top. Plus there really wouldn't be anything put inside of it as it wouldn't fit.
Also with all the stuff I carry, that's the last thing I want is to have it lift it higher to get it in the bed of a lifted truck.
