this recurring bellyaching about the rear shocks on the rusty's lift is overstated in my opinion....I have the rusty's coil lift for over a year now....I've been off-road with it several times....went to moab last year and went everywhere the frankenlift guys went....
the replacement shocks for the rear that come with the rustys kit use polyurethane bushings in the shock eyes....there's a metal sleeve that slips into the center of the bushing for the shock bolts....the upper frame mount for the rear is a little wider than the the poly bushing.....at the time, it never occured to me that this was a defect or inferior product....to me, it was just an experience in modifying the jeep and the solution was very simple....fender washers are flat washers with a larger outside diameter for any given inside diameter (bolt size)....they cost pennies a piece at a hardware store.....the outside diameter of the washer fully covered the diameter of the bushing.....I don't recall the washer size that fits the shock bolt but I just put a couple on either side of the poly bushing and tightened the bolt down....I have had no issues with this "fix"....no noise....no loosening over time....cost me maybe $1 for a handfull of washers, if that....perhaps people who have not been satisfied, tried to use a washer that didn't adequately cover the inside and outside dimensions...
I would not disagree that the more expensive frankenlift is the prefered product.....it has been developed and used by the guys who lead this forum....and the vendor (all-j products) steps forward and supports this forum with advertising.....I've purchased his boulderbars and skid and I purchased a front locker from him....I would have spent the extra money for the frankenlift but it wasn't available to the general public when I came to this forum to learn....
some have said that it is difficult to contact rusty or that he is slow to deliver....I believe that may be true but I was lucky to speak to him on several different phone calls and he was very friendly....I've purchased a few different things from him and I alway received the product promptly.....he doesn't include instructions with the lift kit....he expects you to know how to install it yourself.....I don't know much more than what I have personal experience with....I found all the "help" I needed by looking and reading on the internet....I had no problems installing the rusty's 2 1/2" coil spring lift kit and so far, I've had no problems with it.....
lifting the liberty was one of the first things I did.....I recommend that everyone consider it.....it allows for a slightly larger tire fit which then gives an improved differential clearance....yes, it's only a few inches and doesn't compare to the options available for wranglers and xj's....but with skids and boulderbars you'll be pretty much state-of-the-art....
