Its sits level while loaded now with the 3" overload springs. Second benefit before my rear end swatted causing my front end to lift a bit, making my no power steering, steer way to easy making me unsteady at highway speed.
I have 5 tons of gravel.
Leaf springs seem to have more hold capacity to them then what I got on them. But I'm not planning to haul more weight. But it will give me more suspension action while loaded.
And the drive shaft slip joint space didn't even change when I got the gravel cuz ichecked that right after I paid the quarry before leaving. it was a rough road going to the quarry I went to today. And the bumpy roads didn't even move the zip tie method one of you great peeps told me about. So I feel safe about the swap without changing the driveshaft length.
Also I was able to hit 62 mph in 4th gear high range unloaded and I was going 50 mph 4th gear low range loaded on way home.
I'm still not 100% about what I'm doing when split shifting while driving with a load so im just gonna play it safe till I get the hang of split shifting while driving unloaded first. But I'll get the hang of it soon this is the third drive it's been on since the swap. And the first heavy load test drive and it went great I have to say. This rear end was made for this truck. Idk why they even put that other one on it Haha. It was just such a smooth ride there and back it almost felt like I was driving a different truck cuz the suspension difference and speed and braking lol everything!!!
Thank you for all the helpful info y'all have given me.
