Well I took my first trail ride in Co. this weekend and decided that it was probally time to do a SOA. I did not have my rig but from what I saw I do not think I would get the amout of flex that I would need out of my current set up. I run a 4" hell creek with SR in the front and 2.5 longer shackles in the rear to level things out and Bilstein shocks. I clear my 35"s pretty well. The ? I have is the old springs I took of have a 7 1/2 in arch to them is this stock or are they 2 1/2in lift springs? Also has anybody here used proffit cruisers SOA kit. Or am I just plain out of my mind to change things now being I am this far along with my SUA? Thoughts anybody.
