I run 40s on my 2dr 6 speed Rubi.
I did it with:
I did it with:
- flat flares
- 1" body lift
- 3.25" front and rear extended bumpstops (on 3" OME HD springs with 0.5' coil spacers)
- 3" net wheel backspacing
- move rear axle back 0.75" which required relocating the frameside axle bracket back, coil spring retainers, custom bent rear swaybar links to clear axle brackets, and rear lower coil wedges
- generous trimming of the rear fender well
- trimming of the front upper edge of the front fender well
- I may eventually trim the back lower edge of the front fender well
- PSC hydro assist steering
- Dynatrac ProSteer ball joints
- chromoly front and rear axle shafts
- 5.13 gears (remember that I have a 6 speed)
- front axle sleeves, gussets, and truss
- custom rear bumper
- longer bolts from the hardware store to replace the stock steering stops
- Tom Woods 1310 rear driveshaft
- chromoly tie rod
- adjustable front lower, rear lower, and rear upper control arms

nice post. thank you. i already have Tf 4" lift maybe i will have to add a 1" bodylift.
did you move the rear end back for tire clearance or to extend the wheel base?
my front end is already bent so i am going to put in a PR44 and RCV.
i just put hardened shafts in the rear end.
see this is what i mean. i am almost there with what i am already doing for the 37's.
I Brainfuck myself over this crap too much.

Planman rear wheel position looks great. the whole thing looks really good. i probably have 6 months to think about this.
i think i will put my gears in and see what i think of my throttle response on a day to day basis. i drive this almost everyday. (but i don't have to)

Don't need 40's for the rubicon on a four door. Did it a couple months ago on stock rubi 32's with a four door 3.5 inch lift. Need a good spotter and armor up! I plated the crossmember with 1/4 steel and covered the crossover. Plated gas tank with 1/8 inch after the trip. Destroyed stock crossmember on trip. Small tires make for a challenge. Winched one time.
