Re: New WK2 lift

I won't be installing mine until late May; no free weekends. It is very simple indeed - basically a spacer kit but there was a bit more consideration to how the spring is seated, nicely done - on paper at least. We will see if it is a pain to install.

misantrop,
Not sure how many companies will be offering lifts. Other companies which have been advocates of lifting Grand Cherokee's in the past have yet to work on a lift - at least in the e-mails they have shared with me.

Rubicon Express has closed and Rusty's off-road & Skyjacker have each indicated that a lift is not in the works at this point – doesn’t mean there won’t be. I have yet to receive responses from Superlift, RockKralwer and Rough Country. I am sure there are other companies that I have missed in my search.
The IRS on the new Grand will limit some of the desire for the aftermarket to make lift kits - may not be profitable. And, now that Jeep offers the option of QL the market has been further diluted.

Tuff Country does make a 1.75" front leveling kit, which is essentially a spacer kit for the front. The cost of that is $110. http://www.suspensionconnection.com/cgi-bin/suscon/42006-grand-cherokee-leveling.html.

I agree, $400 for Rocky Road's lift is a bit expensive (should be like $279). But, at this point, for those who want a permanently lifted 2011 Wk2, it is the only option.
As to the safety and warranty piece... RROs claim is that because the lift stays within the factory specs of the QLs OR2 setting it will not void your manufacturer’s warranty – I tend to agree.

I know I stated I was hesitant on installing the lift myself as it may void my warranty and now I sound hypocritical. I should have been clearer in my hesitations. I am not very worried about voiding Jeeps warranty – although I am curious to see how the stock springs and shocks – especially the rear load leveling, hold up to a permanent lift, i.e., permanent OR2 setting, over time. I am more concerned that should something happen as a result of me not installing properly; a spring is not fully seated, mess up the alignment, install a tire that is too wide and comes in contact with the knuckle assembly, etc., which would make me solely responsible for the error. If I have an off-road shop do the install they will carry the responsibility of a proper install and take the burden off of me, I hope that clears it up.

I am confident in my ability to install the lift as I designed the lift for my ZJ and have installed numerous lifts, many of which were far more complicated than this, I am just being cautious as this is my DD that I’ve owned all of 6-months.

And, to agree with misantrop, when lifting a vehicle - whether 1" or 8", you will certainly alter the manufactures intended performance. In this case you will alter the center of gravity (CG) which will affect how the vehicle performs. So I caution anyone if you are driving your new wk2 (non-srt8) like it is a Viper than be careful as it is not designed to be driven like that (whether it is fun or not is a different story) and if you lift it, you'd be wise to alter your habits. I almost rolled my '98 ZJ - which was lifted 9" and had 35's - because I took an off-ramp a bit too fast. There is a big difference between 2.5" & 9", but both are higher than factory design for high-speed (40+) driving.

Allright, that’s enough of my parenting session...

Re: New WK2 lift

I am hoping within the next year or so even the QL vehicles will have something like the johnson rods used on the LR4's to get a bit more height out of it. Not neccesarily for bigger tires and to have installed all the time, but at least for those offroading days where you really need just 1 more inch of travel.

Re: New WK2 lift

I think dogface is saying to install this on a QL equipped jeep to have the permanent lift, but not raise the vehicle with the QL after its installed. Correct me if I'm wrong dogface.
I have a QL equipped Overland (canadian) I would love a lift and have thrown the idea around of maybe swapping out the QL in a year or so. I bought the Overland for the trim level I wanted and not the QL. I wish they gave you more options of configurations when buying these.
Although I've put 32" MT's on and have had my Jeep out in some pretty knarly situations and its handled everything I've thrown at it. i'm not saying Ive gone extreme offroading but have done more than most with the GC will ever.

Had to pull my buddy and his TJ out of a mud pit that my GC ran no problem.

What i was trying to say was that the JGC was designed to handle a max height that is the same as this lift. The lift height is the same as a QL equipped jeep at it's maxed out height.
This lift will not work on a QL equipped JGC, at least right out of the box it won't.
I'm just happy that other people are guinea pigs right now. Can't wait to get home to my jeep, if it ever gets delivered.

Re: New WK2 lift

They claim that lifting a non-QL Jeep by 2.5" will put it to the same max height as a QL Jeep in OR2 mode, but I believe that is incorrect. I have confirmed that non-QL GCs sit about 3/4" higher than QL GCs in Normal mode. I have done this comparison myself, and at least one board member has done it with his two GCs. I think they made a mistake in assuming that a QL GC in Normal mode sits at the same height as a GC without QL. Nothing in any literature I have seen from Jeep, or in any review suggests to me that normal mode equals same height as a non-QL Jeep, but lots have people have jumped to that conclusion. All they state is that on a QL Jeep OR2 is 2.5" higher than in normal mode with QL.

That's correct, ORII height is 10.7" and it lifts it 2.6" leaving a normal ride height of 8.1". Non QL JGC have a ground clearance of 8.7".

Your numbers sound correct (from what I measured), did you see that published somewhere, or just observe it ? I'm seriously considering putting the front only 1.75" lift on. That and some slightly larger tires should get me pretty close to ORII clearance at the lowest part of the vehicle without the need for airbags. It seems like clearance wise the front suspension is the weakest point. I also think it looks a little silly having the front sit lower than the back.

If My stock Non-QL Jeep with 265 60 R18's (30.5" diameter) sits at 8.7" then I could do the following:

1) Swap the tires for 265 65 R18's (31.5" diameter), so it would then sit at 9.2" (1/2" higher)
2) Add 1.75" to the front clearance with the leveling kit. I'm not sure where the lowest part of the
car is, but I'll bet it's somewhere near the front, so that might give close to another 1.75" of
clearance to the lowest part of the vehicle, bringing total clearance to around 10.95 which
would be about 1/4" better than a stock QL Jeep in ORII mode.

I think I'm going to do this.

I pulled the numbers from edmonds.com, so they could be off by a tad.

I like how you are thinking here, and am seriously considering also installing just the leveling kit and possibly new tires. The only thing that jumps out at me is that on my GC with skid plates I measure 8.5" front clearance, 9" mid vehicle (directly between front and rear doors) and then 9.5" in the rear to the bottom of the exhaust. If thats the case you'll probably only pick up about 1" additional OVERALL clearance with the leveling kit (still good!). I actually prefer the smaller lift and think the extra 1.5" overall with tires is exactly what I'm looking for.

The only thing holding me back is how it may effect the driveability on road. I've never lifted a vehicle before so am a little cautious about messing with the great ride of the WK2. Although I had the same reservations with the BWoody sway links kit and things turned out great.

Good info in this post - thanks to all!

I think that using your measured numbers, here is what you would wind up with from 31.5" tires and the 1.75" front kit:

Front: 8.5"+1/2"(tires)+1.75"(kit)=10.75"
Mid vehicle: 9"+1/2"(tires)+0.875"(half of front lift)=10.375"
Rear: 9.5"+1/2"(tires)=10"

This setup looks really good to me

Re: New WK2 lift

Bigger tires will add permanent error to your speed readings. In your case it's not much, just 3.17%. Same percentage should be added to an increased momentum of force. It is a permanent extra load to all driveline components and to automatic transmission.

... It doesn't sound too bad to me.

I just wander what would be worse: to have 0.5" + 1.75" (tires + lift);
or just a 2.5" lift. Difference between these two options is almost nothing, but at least we don't affect driveline and speed with second option.

Re: New WK2 lift

Why would you do the 2.5" lift without putting on bigger tires?

In my opinion, the stock 30.5" tires look undersized for the stock wheel wells and ride height as it is. The Jeep would probably look pretty silly with the stock 30.5" tires with the 2.5" lift. I know when I put mine up to ORII level with the stock tires I kinda laughed...

The 32" tires fill it out much better.

I bet the above mentioned setup with 1.75" leveling kit would look good. Definitely get 32" tires though. 275/65/18 work.
