Moving front Axle forward

Well as the title says i'm looking to move the front axle forward 2-3 inchs. I want to still retain the my current springs and shocks. I was going remove the front mounts and move them forward or possibly make new ones up, but that there is the least of the issues ill be coming across i guess. I am wondering what troubles will i come across with steering and panhards. have others done this what other things did you come across that had given you trouble.

thanks all for help in advance

to my knowledge noone has done this on a JK yet. you will have to move everything forward to keep the stock steering geometry. sounds like a fun project.

something similar to what I plan on doing for the next wrangler model. a 2 door stretch with 42" tires

As stated above you really need to move pretty much everything forward.

The springs will be badly bowed unless you move the upper spring buckets, there may some clearance issues with steering etc but I think you'll be okay, although relocating the track bar would be a good idea, as would shortening the sway bar arms. You'll need new control arms and most probably a new drive shaft.

Why are you moving the axle forward?

We tried to push the front axle forward over 1.5", but the front coil springs were not happy. We had to shorten the arms and only push it 1" forward. That is about all you can get with out moving your spring mounts. The stock driveshaft was fine, they have alot of extra play in them. If you have an aftermarket drive shaft you may have some issues. I tried to replace mine with a Je Reel and it was not long enough, so Tom woods made me a custom length one.

Teraflex's full flexarm suspension extends the front about 1" vs stock. It's because of their rather odd front spring design which uses an offset upper spring seating coil. This tilts the spring rearward on the right side, and forward on the left. This unfortunately causes the end of the sway bar (and TF's links) to hit the LF spring. if you try to shorten the control arms to eliminate the contact the springs start to bow badly. It does ride and flex ok, but it's a PITA to stop the sway bar to spring interference. I ended up using Poly's links to raise the bar enough to eliminate it.

X2 A much simpler solution that works well. Bodyguy did this using his own bumper and he's got a great approach angle

doing this would cause some problems over here in australia i would have to have a engineer look at this we aren't allowed to cut any part of the chassis. we can cut mounts off etc but they require a engineer inspection
