So I have a pile of suspension components building on the side of my bed to soon be installed on the hoe. I have slowly bought the parts to finish rebuilding my front end and make the tahoe ready for my future adventures. I have all the parts to do the ford key swap with the bilstein 5100's including new moog problem solver lower a arms and Cognito uppers. I re did the rest of the front end when i first got the truck( CV'S, tie rods, pitman arm &bracket, idler arm & bracket, sway bar links, wheel hubs).I already purchased the adjustable panhard bar from spohn Now all i have left is the rear control arms and some new sway bar bushing LOL. I do intend to do a 4.5 suspension lift and up size tires to 35's and that's where my question really comes in. When and why would you use an adjustable rear arm over a non adjustable and would what you say is better for how i'm building the hoe up. Sorry for being so long winded but sometimes I just run these darn questions through my head so many times I gotta ask somebody!!! I don't mind saving up a little longer to get the parts I truly want but in this case i'm not educated enough in the benefit of the adjustable arms to make an intelligent decision.
