A great lift, both in price and features, is the Rock Krawler Adventure Series 2.5" system ($1,334 at Northridge 4X4). Comes with springs, front and rear spring pads (keeps springs from bowing), front lower fixed control arms, front track bar, rear track bar bracket, rear sway bar links. Only additional items you would need are new shocks (Fox 2.0 ride very nice with this lift) and extended bump stops. You may need to get wheels with different back spacing or run 1.5" wheel spacers. This is a high quality kit and is easily installed if you have the tools and basic wrenching skills.
RK says you can run 37" tires on a Rubicon, which you can with 3" bump stops. With 35" tires, you might be able to get away with 2" bump stops.
This was the first lift I ran on my 2018 JLU Rubicon and fit 37's with it. The caster was around 6.5 with the fixed lowers (can't remember exactly, it's been awhile since I had it), with no vibrations or ill handling. You could opt for adjustable rear upper control arms if you want to run an aftermarket driveshaft. I had stock driveshafts and the stock rear arms were fine.
This system won't get you awesome scores on an RTI ramp, but it does perform very well on and off road. I had it for about 1 year and then moved up to the 3.5" Rock Krawler X Factor No Limits system, which handles just as well on road but with much, much, more flex off road.
Northridge 4x4 currently has this kit in stock. If you use a discount code, it's $1,228, with free shipping. PM me for the discount code.
