Anybody use the JBA/Bilstein 4" lift for $1250 on JBA website?

Been looking around for a new lift to replace my RR 2.25. Came across one on JBA for $1250 that's a 4". Doesn't have much info on the website, hopefully somebody will know something about it.

There are folks more experienced with lift kits than myself on this forum, take their word over mine.


But, a 4" in lift in a Commander with Independent Front Suspension, to do it properly, is going to require replacement of major suspension pieces. The kits I have seen (and Don't know the Brand) have replacement steering knuckles that are elongated and move the hub placement.


If this kit just uses blocks or longer springs to just increase the distance between the suspension and the body, keeping all the same suspension geometry, at 4" it will likely put drive shafts and tie-rods, maybe even ball joints, near their limits for angles. Which could mean lots of broken or worn out parts in your future, and perhaps poor handling. (I could be wrong, but I'm confident at 4" you had better make sure its a "quality" kit doing the lift "right" or you could regret it).

I'm having to rebuild my rack and pinion due to the stress my RC 2.5" lift is putting on the tie rods. I wonder if it's possible to put longer ends in to lower the angle?

Just a heads up that you may have problems with that.

Thanks for the input. I emailed JBA and got a lot of info from them on this kit. I've also seen other companies that sell a modified OME
4" kit. I don't know if I would want to go through all the hassle of broken stuff just to fit a little bit bigger tire under there. I might just have to save up for the Superlift and do it right.
