I don't necessarily know what acceleration and performance SHOULD feel like, but mine doesn't seem to be atrocious so if I had to guess I'd say it was the higher one.... like the axle tho I'll check when I can....Your 2” spacer and 33’s on an aftermarket wheel with good backspacing and the Dana 35 should be ok as long as you do light wheelin and don’t disconnect your swaybar.
As mentioned, that tire size on factory gears will result in less performance than stock. If you have 3.73 it’s probably livable. The 3.07’s would be worse.
Flat flares will probably not increase the space for your tires. It’s the fender that is the bigger issue. If you replaced fenders and flares, by a company like JCR or MetalCloak, you could get more clearance for tires. A small 1-1.25” body lift will also give you more clearance for tires, and is a cheap and good solution.
Your shocks might be skyjacker or Rancho, hard to say. Shocks control your ride quality. It only matters as far as your preference in ride
Last thing, you might want to measure your actual lift amount, considering the fact that your stock coil springs might be sagging. To do this measure the spring and spacer. Stock front is 12” and rear is 8”, so anything greater than that is actual lift.at least then you will know where you really stand.
also this may be a stupid question but what exactly is the difference between the flare and the actual fender?
& I feel like everything I read about body lifts is completely against them but are they really that bad? I get that they don't get you the flex of an actual lift but then again neither does a spring spacer and that's what I'm on right now. I'm just thinking if I can spend a little for a body lift until I have the money to get a quality 3.5" or so lift, that may be the best move so long as body lifts aren't actually the devil like I've read about them.
