I installed my new rk 2.5 max travel lift about a month and half ago, and I didn't noticed if it was sitting like this at the start, but now it seems to sag a bit on the rear.

My jk is a 2 door, with custom front bumper and winch, xrc rear bumper, genright steel tire carrier with 35 nitto mud grappler spare, and hi-lift on the tail gate. Most of the time the back seat rests in the shed and I have a 50-60lbs tool bag in the trunk.

I got a tall 3.75" of lift up front, haven't found any precise measuring points for the rear but seems to get 2.75 to 3" of lift.

I know RK lift have progressive coils up front and linear coils in the rear, so it might be the answer? or they're just over loaded.

So, anyone else had this happen? I guess I should get 3/4" spacers to compensate the weight.

 

I have the RK 2.5 Max Travel and mine is running a little lower all around than it was without everything (of course). I have a 4 door and its running very heavy. Steel bumpers, winch, lights, 35" toyo and 18x10 on the carrier, heavy sub box, and a full tank of fuel it definitely sits low. I ordered 3/4" daystar spacers to bring it up some but they are currently backordered at Quadratec. I know RK builds some height into there kits but I lost all of 3/4" with all the extras on it. I want that height back.

 

I have had my RK 1.5" triple rates on now for a month or so (front been on a couple months ) No sag on the front 14 jkur with stock bumper and VR10000 winch and rockhard4x4 skid plate and winch mount. Rear has stock bumper and about 85lb wheel combo and it has sagged 1/2" already starting to get the squatting look. My 1.5" tera flex performance coil kit did the same so maybe same spring supplier. If it sags anymore I will have to put a spacer in back. I guess maybe stock coils are superior for resisting sag as I never had that issue with the stock coils and spacers.

 

I had to add a 1in spacer from my old tf leveling kit in the rear of my 2.5 flex kit. Seems to be a trend.

 

Do you have any pictures of the rig from the side sitting on level ground?

These pictures should be a sticky. It's the factory measurements. Measure the same locations and subtract the stock numbers to get your lift height.

 

ho and while you're here, I'm trying to email RK since like the beggining of june to get a 2nd sticker to put on the other side of my jeep but I have no answer. :/

According to these measurement, I have like 4.1" in the front and 3.8" in the rear.(that's a lot of lift for a "2.5") I took them at the same tiime as I took this picture (5 min. ago) It's not a big difference finally, Maybe I'm just crazy And I have both the rear seat and my tool bag in the trunk with these measurements.

 

my coils did not come with any decals/stickers which I thought was strange as most companies like the free advertising. I just left my AEV decals on. I figure if RK is not going to throw a few in with their product they do not want the advertising. I have had 3 or 4 people stop and ask what AEV lift I have as they said they were looking to get around the same lift height as what I had.

 

I had one banner with my kit (the one on the bottom of my door), but I'd like to match the other side too!

 

I would display that on my windshield if I would have got one. Good luck seems like your jeep would be good advertising for them, looks good.
