Rock Krawler 3" X Factor JT System

Holy crap, thats the exact backspacing they recommend and you are rubbing? Why does that rub for you, but the RK post with 38's and 4.54 BS still looks to have a few inches left in their picture? What am I missing?

Possibly the model. Axles ont he Rubicon or Sport S w/ Max tow are wider. So the overland being a bit narrower may be the difference there.

Ah, good point. I forgot about the Rubicon\MaxTow axels being wider. I guess I should update my original post and ask specifically about the JTR with this lift and 37x12.50x17 on 4.75" backspacing. I really like the wheels, but if I order with the tires mounted there are no returns. Id rather not take the gamble if one of you fine folks has already

Your talking about 1/4" of backspacing, but a 1" narrower tire. Should equate to 1/2" of difference on each side (assumeing same tire model & wheel width) so I would think your fine. Thats my uneducated $0.02 though so take it with a grain of salt.

An overland has narrow width axles and needs to follow the guidelines of the sport models. Our example was on a Rubicon which has the wide track axles and allows you to run a greater backspace.

I’ve got the Pro-X installed on my Overland and paired that with Black Rhino 17x9.5 with 4.5 backspacing (-18 offset). I put on 37x12.50 Ridge Grapplers and I ended up rubbing the control arms at full lock either way.

I ended up having to adjust the steering stops with a couple of washers to eliminate the rubbing. (For reference:http://www.4x4xplor.com/steerstop.html)

On an overland, you'll need to be closer to 3.5" BS as you have the narrow width axles.

Thanks for responding RK! Do you know of anyone with a JTR that is running this lift with Ridge Grappler 37x12.50x17's on wheels with 4.75 backspacing? Your picture looks like there would be plenty of room, but Id rather know for sure than order and regret it.

Finally finished with the lift, turned out good IMHO and rides much better than a stock LE Rubi

My Pro-X kit has finally arrived (damn you Corona)!!! To say I'm stoked after reading this thread, is quite an understatement. I'll be heading from Miami to Charlotte tomorrow to visit an old friend who is also an RK lift Jedi, to help me install it. He says we can blow it out in a day, so I'll have an extra day to do some wheeling in the mountains up there before heading home Monday morning. I've never been off-roading in NC or TN so it should be fun. I hope I can hang, he has an insane JKU on 42s.

Just ordered this kit from Northridge with the RK shocks, hope it lives up to the RK kit I had on my JK

Ordered the X-factor no limits kit for my JT Rubicon just over a week ago and got everything but the track bar and box kit. Saying 15-20 days for drop shipment from Rock Krawler! That is a long wait. Northridge was supposed to check with Rock Krawler to see what the times look like but unfortunately I have not hear back from them yet, so here I sit and wait and my tires and wheels are supposed to be here next week.

A week is not a long wait, I waited 2 months. Remember manufactures are still ramping production back up from covid19

No shit ?? Northridge showed everything was in stock when I ordered yesterday ... Hope they don't screw me like that

No a week is not long and that wasn't to bad. It is the 15-20 days that I may no make it thru. That is like an eternity lol!

I have a question for you guys/girls ... Can anyone provide a rough height to the bottom of the front fenders on a sport with this kit and 37's?? I know everyone will be different with different winch/bumper combos and every 37 is a little different in height etc ... I'm just looking for a rough measurement to compare with the parking garage at work while I'm waiting for parts to come in to make sure I'm still going to fit

Better to ask for roof height
