Angled or flat rear lift blocks?

[BigIslandBoy]

I'm thinking of adding an 1" before I put on my Pro Comp traction bars. I currently have 5" Icon flat blocks with bump stops and my wheel sits back in the fender well. I plan on switching to a 6" block. Are angled blocks better than flat blocks? I know angled will center my axle better but is there any advantage other than looks? Are bump stop tangs needed as well on them? Thanks in advance.

Angled blocks will reduce driveline angles. To center the axle I believe you need the blocks with adjustable top plates that are sold by OUO. When I was at 6" lift I had angled blocks and my axle still sat back in the fender well. When I got the OUO traction blocks we were able to center it up.

I am probably going go with these in 6" Fabricated Unitized Lift Block - Precision Metal Fab or the Icon 6" blocks. So you are saying that angled blocks improve driveline angles. But doesn't a drop carrier bearing kit like the Icon one I'm running do the same thing? I don't notice any vibration or shutter at any speeds. I also may buy this ajustable carrier bearing unit Adjustable Center Carrier Bearing Drop Bracket - Precision Metal Fabeven though I'm not having problems with my current one.
