2” block lift on rear of 2020 TRD off-road

I currently have 1.5” lift blocks on the rear, (2” lift up front), and was thinking about going up to 2” blocks in the rear to give the rear end a bit more angle. Truck sits about level as is. Question is, are there any other modifications I would need to do for 2” lift blocks in rear? I have 5100 shocks now so maybe a longer shock, but aside from that is there any other mods needed like extended brake lines, or drive shaft carrier bushing drop that must be done?

 

Extended brake lines, no.

Carrier bearing spacer, maybe. I have one because it came in the kit I bought from headstrong off-road

 

Might end up with some driveline vibrations. I would have some rear axle shims on hand and maybe a carrier drop.
