Nope. I only had to cut one thing. You have to cut off the stock lower control arm pocket due to the kit actually dropping the diff the whole 7" down. Most kits only drop the diff a few inches and you have to crank the T-bars like crazy to get the full lift which in turn gives you some nasty CV axle angles. The Cognito kits drop the diff the full amount so at the lowest setting (7" or 10") the CVs are flat and then you can crank the extra 2" if you want and still have great angles. Also most kits require you cut the top mounting ear off the front diff. Cognito does not. Its truely a bolt on kit... well, had to drill a few holes. If youre somewhat local, you can check it out sometime.
