Yeah mine rode pretty shitty with spindles and drop keys. Then I added the control arms and it was much better.

Does using the upper & lower control arms help bring the turning radius back? My turning radius has always been crap, but I've been too cheap to try new parts....

Front: DJM LCA (3" Drop)
Lowering keys (2" Drop)
I only used the lowering key for about 1.5 inch drop but the great thing about using the lowering keys is you can fine tune the height to match the rear.

Rear: Shakles / hangers (4" Drop)
Remove Blocks (2" Drop)

Get some decent shocks and I added a rear sway bar. Ride handles great with a sporty feel.

I'd like to get the DJM upper and lower control arms and some drop hangers some day, as well as maybe some 275/45-20's instead of the 285/50-20's that I'm currently running...the truck sits nice now, but I'd really love to slam it to about a 2wd 2/4 or 3/4 type of height. I can't help but be concerned about the front cv joint angles though...as it is right now, the front axles are angled upward about the same that they were angled downward when the truck was at stock height with 33's, so I feel very confident/safe about them. If I can ever afford to drop it more, and convert to AWD, does anybody feel that there should be a concern?

I'd like to know this too Roger...IIRC, the control arms don't affect the turning radius, but I'm not 100% sure. I believe that I've read of guys with spindles grinding down the stops to allow for a few more degrees and allow for getting your turning radius back...

Black04 would be the one to ask about CV angles. His are by far the most severe I've ever seen. He's claimed(in the past) to have zero problems with the CV's.

Maybe he doesn't "test" them like I would... I test mine regularly.

Yep, I've inquired with him in the past and have gotten the same response As you mentioned, my 4wd also gets used somewhat frequently in the winter here in Jersey, and I've gotten in the habit of using Auto4x4 every time it rains, as it seems to work very well in that scenario. I'm sure that you use your 4x4 much, much more frequently in your neck of the woods for sure

When I had mine slammed I didn't have a single cv issue.. I could brake stall it 3200 and it would launch straight as an arrow.. Haha now it plays hop scotch if you do that lol

I had about 4.5" of drop in the front.. I would reccommend if your gunna do it go ahead and do it right and do flip kit and notch in the rear and uppers and lower control arms in the front.

When I way "test" my CV's, what I really should say is "4x4 burnouts and/or drifting on dry pavement, bouncing off the rev limiter at times...." lol

I agree, to go really low, the flip kit/notch is by far superior to hangers/shackles. The ride quality is better, and the suspension geometry is also better. Especially if drag racing is part of your plans.
