I'm installing a Tatton Rear DS on my JK. I bought JKS rear upper control arms to set the angle and JKS spring perches to make sure my springs stay straight.

Am I also going to need an adjustable Rear Track Bar since I assume I won't be able to rotate the axle and keep the track bar mounting flanges aligned with the factory bar ???

Thanks ...

 

After installing Woods drivetrains, I corrected rear pinion angle with adjustable UCAs, but I got interference between the top of my diff cover and my factory track bar. Spring shims and a JKS adjustable TB was the remedy.

No binding and no interference.

I'd do the TB too.

 

Thanks .... I guess that delays my project a week ... I just ordered the JKS Rear TB so hopefull will have it for next weekend. I already have the adjustable spring perches so I won't need the shims.
