"Gonna do it right...maybe!!??" Fuller's new XJ build!!!

If your relying on the floor pan to be your bump stop to keep the trackbar from crashing into your oil pan and into the crank is a bad idea. That floor pan will never stop all that from happening, maybe with just jacking it up but with the full weight of the rig bouncing over bumps the floor will give in. Have you even cycled the suspension with no springs to make sure nothing hits?

No no I'm not using the floor just saying it would hit so I have to bump stop the driver side for that.

At 1" uptravel? That is going to be very lousy to ride in. Maybe you should think about getting some in person design help on the front.

Why, JKs run 37s on 3.5-4"lift all the time with 1.5" up travel or less so don't see the big deal. Sure it sucks for driver side flex up but it will work..I've had very similar setup before and rode just fine. Compared to any and all crawler I've had, this rig gonna outperform those by long shot and ride quality not even camparable. (In actuality I'm looking at it it's more like 1.75 before hitting floor board before I trim the floor)
 
Allegedly there's a JK somewhere in this pic with a 4" lift and 42s...I'm still looking for it though...

your math.... its wrong......
factory jks have roughly 4" of up and down travel. you add a 4" lift, you are now looking more like 6" of travel both ways.......

That is nowhere near being accurate, good luck with whatever you do. My patience is gone I gotta step away for awhile.

Okay yeah I got my math wrong apparently but I know what I'm talking about I know I've seen tons of JK's when I lived in Boone at a certain shop they had hardly no lift running 37's with practically no up travel.. but whatever I don't see what the point is it's not like I'm the first and only person to run small up travel.

good luck with whatever you do. My patience is gone I gotta step away for awhile.
Dang bruh, don't be stressin. It'll all work out, always does.
 
You got this bro! Don't listen to the haters! (I hope your dentist and chiropractor are cheap!)
 
Ya I’ve rode in several rigs with little uptravel they suck for trail riding. Raise your rig 2-3” and you will be 1000X’s happier

I went back to pg 37 for a pic of the front....

Where is the control arm going to contact the floor? Near the frame side joint? If it has 1.75" of clearance there, that doesnt equate to 1.75" of uptravel at the axle.

As others have said, you really should pull the springs and compress the axle upto the chassis to see what hits when, and then bump stop it there. I bet you have more uptravel than you think.

If you are referring to the jeeps at high country 4x4, I wouldn't base my suspension travel and geometry on those.....
99% of those jeeps will never see a dirt road, let alone actually be wheeled.....

Great...I thought I only sprayed coffee all over my computer at work. Now my wife's gonna be pissed! :lol:
 
Compared to 4way leafs and blown shocks, this gonna be a Cadillac:D

Worn leafs and worn shocks will actually ride very softly.

Not beating you up buddy, just educating you a little.
No lift is completely different from no up travel. You can run zero to 2" lift on a ____ with whatever size tire assuming you have flat fenders/fender trimming to allow for tire movement upward. Look at a JK on the dealer lot and you'll see more than 1" of uptravel.

First hand experience here: I used to have my Ranger set up for 2" of up travel on 14" air shocks. I liked the low slung look when it was on 37's. It was mean looking being all low and everything.
Until I hit the first trail. Then it sucked. Right back to the trailer, unhooked the limit straps and set it up for 6 up/ 8 down. Much, much better.
 
This circled area is the floor pan right below the gas pedal. That is where the upper arm WILL hit. When I had my 3 link setup very similar and flexed out under full weight of the vehicle it hit and dented the floor pan in about 1.5 inches. Completely a non issue. But like has been said numerous times. Take the springs out, get rid of those stupid paper towel roll looking spring holder thinga-ma-jingys and cycle the axle. When the axle bumps take notes and set your bumps.

Ok sorry I thought if there was 1.75 before arm hit the floor that meant same up travel but now I see it doesn't so I guess I do have more than I thought. Shocks have 4" roughly before topping out so that should be plenty.
My shocks are set up for 4 up and 7 down

How much room is there between the bump stops and whatever they bottom out against?
i.e: what is your uptravel?

How would you personally go about figuring that out?
Would it work to remove the springs and cycle the suspension with a jack?

No you idiot you take a jar of marshmallow fluff and stick it on top of the Tp tubes and jump up and down on the front bumper 6 times NOT 7. Then you measure of the fluff spread in 5 locations around the circumference of the fluff squirt find the standard deviation multiply by 7.42178 then divide by 1/457 add 2.432 and you know how much up travel you have. Its really quite simple.

Don't forget the exponential function! You almost forgot that part...

Pissing myself...thanks for that!

I haven't made bump stops yet, took out the pipe inside coil springs..not needed.
My shocks have 4" to go up from ride height and droops down 7" is what I did.
