4 link kit was next from sticky fab which is bolt and weld at the factory crossmember location.Front axle fab followed.All stock brackets were replaced with 5/16" steel.Yes I know it's a polished turd. Cyroed 4.56 spicer ring and pinion installed with REM finished bearings for the traction 3 year old Aussie locker used out of previous XJs.WJ knuckles and brake for upgraded steering and stopping power

Steering and track bar was out build using components from barnes 4wd and Wide Open Design. Broke a 5/8s bolt on the old jeep.So will not be problemhp on this one.All 3/4" bolt on steering and track bar.Track bar mount was a 2.625 mount so custom spacer was needed.Driveshafts were next which I do everyday.1310s .250 wall tube.1350s next with the JK tcase.

First day out of the shop was May 14th.First time having gears and brakes and its awesome.But the polished turd made it 30 minutes before the carrier broke after a good clutch dump.Taking out the pinion.Sucks but new parts were here the following week.

Night 2 out no breakage just some parts moving.Didnt put the lower bolts back in the track bar mount.Causing the unibody to separate and move the mount over a few inches.Also found the driver upper hitting the front yoke due to much pinion angle.

Can you swap axles and still be in the stock class?
Yes but it must have factory style suspension configuration

Thanks for posting! I’ve been wanting to get a XJ and go racing too. Nice to see some tech on it.

I got the hooligans stiffeners also. Had the same problem and multiple track bar mount issues. There’s just so much chassis flex on those dang unibodies. Problem solved with a trackbar brace(under oil pan to passenger rail) and a 4.5”x1” bolt through the outside stiffener to the inner plate behind the steering box. Pardon the crappy picture.

I will be there but not racing this season.To many things to buy between the baby and safety equipment.
