the front and rear shocks are differant. i also have the 20% stiffer bilstien shocks at all 4 corners. i removed the rear sway bar and the 20% in the rear compensates for the little extra body roll you get from removing it. the ride is so much better now then the stock shocks. before it felt kinda mushy now it feels just right. they are very easy to replace btw. that was the first thing i did on my truck alone. save some money and order then online and do the work yourself. im sure there are directions around here somewhere but its pretty straight fwd. i had some trouble with my front ones and got pissed and ended up cutting them off with a sawzall. i spent about 3 hrs trying to figure out how to get the front DS shock off and tried everything and just cut right below the top nut and had the new one on it about 10 minutes. i went straight for the saw on the pass side. rears took me about an hr.
