Re: T-case lowering..
Thanks Evan. With 6" I guess they would be. 4" I think is borderline, they shouldn't be necessary, in my opinion - maybe I am wrong? I put them in on my friends advice when I did the lift, and haven't taken them out yet. He's run with them for 9yrs, but doesn't wheel as hard or carry heavy loads like I do. They do make me nervous, and the reduced caster gives the steering a slight wobbly/wandery feel. Its my daily driver as well, so I notice it. I plan on taking them out. Two other friends of mine have 4" as well and no shims, and as yet no problems with vibration or other, and they are pretty hard on their trucks. Whats your opinion on 4"? You seem to know what your talking about.
Sorry to barge in on your post Big Bear, just tweaked my curiousity.
