I'm about to go jba 6 lift. What is your lift and what all did you have to do on it.
I went with JBA also. 6" left is perfect too. You can go up or down on the adjust a struts and the package of shocks and front steel diff had been very good. While I'll admit I'm hungry for a SFA, JBA stuff is top notch, I think. He also knows his stuff and if you have questions about the build he's helpful to answer. My recommendation is to get someone with attention to detail on putting that stuff in. The arms have to be cut just right and so on. If you do that, you'll be very happy. He's pricey, but his stuff is very good. I wheeled hard for a week straight on his lift and was anticipating my IFS to give out or break on some of the pinches I was in but it held up very well, no issues. Again, SFA is the better build on my opinion, but if you're ready for a lift, I'm very happy with my JBA. The parts are tough and doing very well so far.
My work so far...
JBA 6"
Adjust a struts
Bilstein front/rear
Brake lines
Tri-Angulated 4 link
Upper and lower arms
Steel front diff
2" drop
Rear coil springs
Extended bump stops
4.5" arms, etc.
Recommend spacers (helps with spacing tires from arms when u r deflating the tires for off roading)
That's just a simple list from JBA stuff. there's more that I did with lockers and 4.88 gears and compressor and louvers, etc but have been pleased with JBA.
I'd definitely get a 6" and not the 4" And I'd recommend lifting the front to even the plane for the rear lift. Usually a Libby has about an inch more lift on the rear than the front but I evened up the front with the rear and she rides much better. Just a suggestion.
