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.
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...
