I am a Quadratec fan, but their private label lift kits appear to be Skyjacker parts. We haven't had a lot of good reviews on Skyjacker, primarily on their shocks. I would add that the axle side rear track bar bracket isn't braced and I certainly would NOT go anywhere that I might stress that out.
I would suggest that you go at least up to the TF 2.5 and use the new Rancho RS5000X shocks.
This post goes over our recommendations, although it includes the more expensive RS9000XL shocks.
