Which Currie rear track bar for LJ Rubicon?

I am looking for some guidance on whether or not I will need the bracket with the added angle for the currie trackbar. This makes sense on a TJ, with the extremely short rear shaft, but will the geometry be correct on an LJ? Should I use the rear trackbar without the bracket?
 
Depends on how much lift you have and corresponding correction to your pinion angle.

If you rotate the axle for more pinion angle then you need the angled bracket to keep the track bar from contacting the gas tank.

Fill out your profile!

Thanks @macleanflood

Planning to install currie 4" lift. Wondering if that amount of lift will ever be high enough to need that much angle.

Saw another user mention binding but they also had relocated lower shock mounts
 
TJ certainly.

LJ... guessing probably not.

Are you planning on a SYE? Slip Yoke Eliminator?

There's no difference in the bars...one comes with the bracket, one doesn't.

If you find you need it then you can buy it later.

Being a Rubicon is irrelevant. If the rear driveshaft needs to be a double cardan with the rear pinion raised, then you need the rear track bar angled relocation bracket.

He asked if I was doing a SYE, so it's relevant.

Do you have an LJ? I imagine the pinion angle is much different between a TJ and LJ, so what angle is the bracket designed for?

Bracket is designed to keep the track bar from contacting the gas tank if you've rotated the axle to fix pinion angle as stated.

Fixing pinion angle is probably more relevant to my 97 TJ than an LJ but every suspension can be different...and the bracket is there if you need it to solve a clearance issue.

The angle is designed to keep the axle side track bar bracket away from the rear upper shock mount/crossmember after raising the pinion, whatever angle and axle position that is.

Knowing myself and how I would build an LJ with a 4" spring lift, the presumption would be a double cardan rear driveshaft with the angled bracket because I know crashing the track bar bracket into the crossmember can be avoided with the angled bracket. I am also not an advocate of cutting corners very often where I know better.

On my LJ with 4” Currie springs the RJ bracket was required with the RJ track bar with body lift and 1” raised transfer case skid. With the Core 4x4 rear track bar i was able to remove the bracket and only touch my 1” raised fuel tank skid when full stuff.

I’m gonna say from experience use the RK bracket with the RJ track bar and if you don’t tummy tuck you’ll be fine if you tuck the tummy expect some fuel tank skid clearance to be needed.

My experience

After about 3" of lift, I switched to a DC shaft. The stock LJ Rubicon shaft was maxing the joints out at full droop.
I tried an angled bracket, but it didn't work out.

The angle of the bracket was pointing too far forward. Ideally, it should point up at ride height.

What resulted from the angle being pointed too far forward?

The same angled bracket gets used with TJs and Unlimiteds both with and without raised bellies. That's a wide range of pinion angles that don't all point at the same up at ride height.

The trackbar and it's bushing (ideally) should operate in the same plane as the axle travel, which is up and down. Having the bracket point forward was less than ideal. My setup works just fine, no angled bracket needed.

Currie/RockJock solved the misalignment problem by using Johnny Joints with wobble stoppers on both ends of their track bar.
 
Do you disagree with my explanation of how things work? Feel free to correct.

I know how things work. That's why I bought an angled bracket.
After cycling my suspension, I determined that I didn't need one.
