For steering you can't do hydro assist with the rack. You can convert to a steering box with ram assist. I personally never had an issue with my rack on my race kit since that steering location is better than stock to optimize the bump steer curve. Also without pushing the front end forward 1-1/2" or so the 37s are gonna need the door hinges cut to clear a bump and partial turn ESPECIALLY without a lift spindle. Going to a lift spindle would alleviate a ton of those problems BUT isn't possible with the 4x4 kit and stock spindles, which is the major draw back of these 4x4 trucks and retaining 4x4. Going to a portal would help but cost prohibitive and would require a complete front end redo.
Also going to 37s with stock unit bearings and stock front diff I feel will be the weak link and the benefits of 1" more ground clearance might bite you when you're broken because of that.
