Tim, Id reach out to these guys, they do a ton of lowering and sell suspension parts for these, they will guide you to what would probably work the best.
I cant compare the two. I went from bilstein to viking and i learned that it is very important to measure to ensure you are getting the proper length shock. Dont take the word of a vendor, trust but verify.
I was originally on a Vas Fab/Viking front with Fox 2.0s in the rear. The Vikings went out and were squeaking like crazy and it was driving me nuts. I ended up needing to swap to a Ridetech setup and couldn't be happier.
