Ultimately, the build to work towards for strong, reliable, well performing 35" tire builds looks as follows
rear 44 chromo shafts
front hp 30, or rubi 44, chromo shafts, ctms
currie steering, with knuckle flip and raised swaybar links
currie specific hydro assist from psc/savvy
currie trackbar
walker, raceline, poison spyder, kmc, trail ready aluminum beadlocks 17's 5x 5.5
johnny joint suspension (2-3")
small body lift 1-1.5"
tuck belly and gas tank
swaybars front and rear
outboard rear shocks
If you keep it low, a good quality short arm will wheel and handle as well as a long arm. The swaybars will significantly increase offroad stability, as will outboarding the rear shocks. If you can do a dual rate swaybar in the front it will increase onroad and off road performance and handling.
Beadlocks will increase traction equal to or greater then the difference lockers made. Good quality aluminum ones will run true and reduce front vibes, maintenance, and bouts with death wobble.
17 by 5 x 5.5 will eliminate the need to ever by another rim, and increase ability to re sell because those rims are suitable for new jeeps, one ton axles, etc etc. 15's and 5 x 4.5 limit you to jeep axles, and force you to sell at a loss if you ever do a one ton axle.
The hp 30 is stronger then the lp 30, and a good axle for the 35" tire build. You can beat them pretty hard and they have a little more clearence then the rubi 44. Not to mention they are a dime a dozen at pick and pull.
I've done a lot of 35" specific builds. This is an extremely high performance and very reliable build, but it doesnt come cheap in any way shape or form.
Done in stages start with axle strength, then steering upgrades including the hydro assist. Then beadlocks, suspensions links, swaybars, and finally shocks.
If after all that you have money for tucks , fenders, panels, etc etc, you can play with that stuff.
