Default lengthened control arms for axle clearence questions

alright heres the idea

using the factory control arm location, use longer control arms to push the front axle further forward for more tire clearance from the firewall, then fabricate new mounts for coil overs.

the goal is to only use 3 in of lift to fit 38's. im also swapping a OM617 in my cherokee, which has a front sump that interferes with axle movement.

i plan to also push the rear axle the same way and use coil overs with the same control arm setup.

first, has anyone done this before?

and what recommendations for components does anyone have? or any bad jojo's in the plan.

Depending on how far you push the axle forward you might need to lengthen upper control arms. You can only push the axle so far with one set of arns

Uhh... he wants to fit 38's, I am hoping he's realized that the stock upper control arms won't work. Lol. At any rate, sounds like a good plan, are you going to be building your own rear suspension then?

im figuring the easiest way to do it is to use a set of used adj long arms, chop them to length, and just move the panhand bar mount forward, or set it up with a 4 point system.

at some point you might have to address where the coil tower is in relation to the axle?

Mount strength is a big issue you will be increasing the torque apllied by making the arms longer and the added weight of 38s also dont go to far or you will have to relocate battery and ecu and cut the bulge. remember to bumpstop.

mechanical diesels need no ecu. most all the electrical systems will be gone.

it will only be about 2-3"

Do a google image search for "comp cut XJ" and "stretched XJ" and you'll find a lot of build thread photos.

thanks for the direction.

looked at a few builds and it seams better to do a 4 link setup rather than use the panhard bar.

What axles are you planning on?
And you can't just pull the track bar off with a 4 link, if its not a double triangulated 4 link it will wander..

likely a dana 44 up front and a ford 9 in the back. reason for nothing bigger is im trying to keep the weight down in the build.

thats good to know. i plan on double triangulation to start with, so i guess i had the right idea.
