Rock Krawler 3" X Factor JT System

That will replace the correction pads under the front springs and add 1.5" of lift.

You'll want to drill it to accept your bumpstops but it is a nice, simple solution.

Sorry to ask so many questions but I placed an order for the 1.5" correction pads today and started thinking.... There's not much info out there on the install with the bump stops so I thought I would ask. When I pull out the original correction spacers that come with the lift and add the new 1.5" spacers....will the net gain only be about 1" or will it still be a full 1.5" net gain? I don't see anywhere that shows the actual height of the new spacer/pad compared to the one that comes with the 3" x factor lift. Also will I be able to just drill a 1/2" hole in the top of the new spacer to install the bump stops on top of the spacer? If so i'm thinking I might have to get longer bolts to mount the 3" bump stops through the spacer since there is not a lot of bolt left to install the nut right now. And when it's all done I'm thinking I might have to add a little length to the front track bar as well as the front control arms go get everything back in alignment. I used the original specs in the RK install directions and they were absolutely perfect. I'm afraid now this might throw it off a little with the additional height. Thanks for any help you can provide. I know it seems like a simple spacer install but I'm kinda a perfectionist when it comes to my baby. lol

I do not have an image of that setup to share. 37's on a 3" lift sport/overland with factory fenders is going to be tight.

Wish I knew this before I bought the kit, tires and wheels ... guess we'll see what happens whenever I get around to the install.

I have the 3" kit on my Overland right now with 37's and an extra 1/2" spacer on the front coils. I haven't really flexed it out but I can tell you that the only real issue I have is that my 5" back spacing on my wheels is not enough at the tires rub the lower control arms just a little. I put washers on the wheel stops to fix the issue but I didn't plan on that happening. I'm also going to swap out the coil correction pads that came with the kit for 1.5" coil correction pads to gain about another 1" so I am closer to level. Right now I still have about a 1" rake in the front and I want to get it level. I really like the look of the Mojave and wouldn't mind having it sit more like that.

Good deal, thanks for the info !!

If you scroll back a page you can see some pictures and comments on the Gray Overland

Is anyone running 37” tires on an Overland with this lift?

I am but not the pro x

Went ahead and ordered this kit this morning. They said should be able to ship it out in two weeks or so. Keeping fingers crossed. Anything else I should get to go along with this system?? No need for a driveshaft correct??

I think the big take-away from some of these conversations is that the third party web pages sometimes fail to provide the following note found on the Rock Krawler web page for these lifts:

Tire Fitment:
Sport and Overland with Full OEM Fenders
37” Tall Tires (3” Bump Stop Height Recommended)
Sport and Overland with Trimmed or High Lined OEM Fenders
38” Tall Tires (3” Bump Stop Height Recommended)
Rubicon with Full OEM Fenders
37”/38” Tall Tires (3” Bump Stop Height Recommended)
Rubicon with Trimmed or High Lined OEM Fenders
40” Tall Tires (3” Bump Stop Height Recommended)

Wheel Fitment:
Sport and Overland Wheel Fitment Recommendations
37”/38” Tall Tires - Recommend 3.5” of Back Spacing
Rubicon or Sport with Wide Track Axles Fitment Recommendations
37”/38" Tall Tires - Recommend 4.5” of Back Spacing
40” Tall Tires - Recommend 3.5” of Back Spacing

This type of information is a responsible industry standard.
If you choose to go otherwise than what the manufacturer recommends, then yes, you may need to consider spacers, etc.

Max Travel Replaces front lower and rear upper control arms, this gives you the ability to adjust caster and pinion angle but uses factory arms in the front upper location and rear lower location which lave limited amounts of misalignment and will bind earlier, limiting travel and reducing capability.

X Factor replaces all of your control arms with adjustable arms that go to factory mounting points. It gives you the ability to dial in caster and pinion angle while having spherical joints at each connection and help to alleviate binding.

Pro X replaces all of your control arms with adjustable and triangulates the rear to really free up the rear end under suspension travel, gave us the ability to put the geometry that we think is correct for the rear, rather than being tied into the factory geometry. The triangulation deletes the rear track bar and the cross-talk associated with it. The axle stays dead center under the rear of the jeep and does not sweep left to right like the factory geometry forces it to.

How do the above lifts affect towing specs? I have a boat that weighs approximately 5000 lbs loaded up.

My lift is installed. Pro-X "No-limits" with RK shocks with Yeti track-bar, drag-link and tie-rod and Fox ATS steering stabilizer. Rides on 37" BFG KM3's. The ride is excellent. Much smoother and more responsive than the oem suspension. The RK shocks tuned for the Gladiator provide a superb response.

I'm sorry, A bit delayed here.. What wheels are those? Method Racing? They look like nothing in their catalog.

@YAABUGGN - they look like the 311 VEX

@LaterGator - Yes, please give us the wheel specs too, i.e. backspacing/offest.

I've been eyeballing different sets of Methods and have narrowed it down to one of the following:

1. 105 Beadlocks
2. 704 Trail Series (Most likely to choose)
3. 305 NV
4. 311 Vex
5. 307 Hole

I ordered my lift but I'm still waiting on the Front and Rear springs as well as the rear UCA/LCAs to arrive.

My wheels are the 17" Method MR311 Vex. I chose them because they have the highest load rating of any wheels I have found that fit gladiator axles.

It’s been a while since installing my Rock Krawler 3” Pro-X No Limits kit and my last post here in the forum so I’m just checking in with a tip to avoid a squeak issue I had from day one after the installation. I’ve had a squeak coming from the left rear but could never pin point the source until yesterday when I was changing out shocks and adding the EVO 2.5 rear shock extensions.
I looked at the lower spring seat and found that it wasn’t in the right radial orientation but in fact it was installed 90 degrees counter clockwise out of position. UGH. Assembly oversight. I lowered the rear axle as far as possible to relieve spring pressure and managed to wrestle the spring seat so the “F” is FORWARD and the “R” is REARWARD as it should be. The brakeline was screaming “TOO TIGHT, TOO TIGHT” and I had to remove the wheel and caliper to shut it up during the process. I reassmebled everything and took it for a test drive down a bumpy road and success!!! Squeak is all but gone but a BIG improvement. So my tip is “PAY ATTENTION TO SPRING SEAT POSITION” when installing the springs.
In doing all this I exposed another issue of the brake line being too tight. Apparently before adding the shock extensions, the shocks would limit the droop. Now that I regained another 2.5 inches of droop I‘m not cofortable at all about the brake lines being long enough. Does anyone know of any brakeline extension kits???

I used EVO's extended brakelines front and rear on mine. Plenty of slack and fit perfectly
