Ok, so that makes sense...the flange AND the washer-bushing on the inside of the framerail. That's contrary to the picture they have on their instructions...unless it's a view from the rear. Slight correction, the new part# for OME36 is CS042R not CS04R. I don't have them installed yet. As you probably know guys who have them say they offer stock-ish ride and more flex along with 2" lift, but that they are not really optimized for towing. I can tell you, they weigh considerably more than the OEM pack I have, as you would expect. Their rear eye is larger than stock also... ....the Energy Susp 3.2125 bushings (http://www.energysuspensionparts.com/3.2125) appear to be too small for the OME36/CS042R rear eyes. (!) Sadly I bought the 3.2125 kit. Now I need to find something a little larger diameter. Leafs won't go on today.
