No need to change shocks and it is an easy install at a good front end shop.
You will need the alignment checked after.
If you change spindles and not springs or struts you retain your factory ride.
I have done the same suspension change to 3 nnbs trucks and have had no driveshaft vibration in any of them.

My 2010 has the same suspension and GM 20's with 285/20/20 toyo's
