eibach pro lift kit for 3rd gen tacoma

^ this. If you're the Hulk you can turn that collar cold turkey but man...I learned that lesson fast.

 

I did the Pro Truck 2 on my second gen and am happy with it. I think it was made for 3rd gen weight though, it's a little stiff on mine. Mines a reg cab with no extra front weight so its a little stiff at the moment. For the rear I did an AAL and the rear also feels good with the Eibach shocks.
As far as UCA's, it seems to be truck dependent and height dependent. I have mine at 2.6" of lift in the front and I had to get UCAs and went with JBA.
