I never ran HD T-bars with 35" either, but they usually are the solution to front end diving due to braking. I would assume they would just make the ride stiffer and more harsh.

With that being said Rockman...

I had my VX all suspension lifted for a week on 35" tires before I decided to order the body lift kit. There's a road on my way to work that is full of large cracks and the stiff suspension was really uncomfortable. In general, the ride gets harsher as you lift. After the body lift, the VX more like it was before the 35"s because I was only at 2-2.5" suspension lift. The body lift/suspension lift/35" tire combo worked well for me with pros and cons for several years before I decided to upgrade.

Also, I would run my tires a 25-27 PSi to take the edge off the bumpiness.
