All I have to input is, if this is your daily driver, keep it as stock as possible. The 31 spline shafts in the Expo axle are strong enough you dont need to upgrade them with the kind of wheeling Im assuming you're doing. As for the D35, I've never really had a problem with it and it flexes great (to a certain extent of course). I think ttb is fairly simple to work on and can keep your stock buckets. You wont have to worry about the crossmember being too close to your axle (No Straight axle). I personally prefer the narrower stance of the ranger. I've been on some pretty off kilter shit with it and I feel safe enough. Good choice on the expo leaves by the way, I have them and love them. As for the TTB 35, Rebuild it comepletely. Upgrade the shafts (known to blow u-joints), upgrade u-joints, and I would definitely do the D44 knuckles. Keeping this as close to stock as possible can save you a LOT of $$$ and in the long run you will be just as happy. I wouldnt go any bigger than 35s
Hope this helps
