Als Long Arms for use in SFA

[ndz]

Does anyone have any experience with JBA rear long arms?
Slowly working towards a SFA and adding rear long arms would be another step in the right direction for me. While I'm at it has anyone seen/tested the rear 4 link kit by al?

They'd work but don't weld the mounts on till you SFA or you will have to cut off the mounts and move them back for the extra lift needed.There are much better ones out there to allow more flex as the JBA ones,they will limit flex having rubber bushings on both ends,not to mention all the extra stress placed on the mounts from running rubber bushings on both ends.

Ok. I should add that I'm more concerned with strength and longevity than pure performance as this is my DD. Could you recommend a rear long arm upgrade kit that could be bolted in for now, until I'm ready to do the front?

It's all going to be custom eitherway and will require more maintenance.I daily drive mine.Most use long arms sourced from a TJ long arm kit,that is what mine are(all the arms,front and rear).The big issue is that the hieght difference between a IFS KJ and a SFA KJ will require the rear long arms to be mounted father back when you SFA then on a IFS KJ.I'd wait till you are ready to do the whole swap.


You got alot of choices like Currie,Rubicon Express,Clayton,and there are many,many more but you want a Currie Jonny Joint(there are many copies but the actual Curries are the best) or some type of super flex joint on the frame end with a rubber/poly bushing on the axle end.

Looks like I'm waiting then. I've followed enough successful and "questionably successful" builds on LOST and the rest of the web to know this has to be done right. Thanks for the advice and info
