2" lift w/ factory shocks

Been looking online at 2" coil spacers. And it seems like all of them that come with shocks, have shocks are the same length as the stock ranchos. Is a longer shock needed for just a 2" lift front/rear?

Truck in question is a 2016 F250 with the factory overloads & 2" rear blocks (Going to swap them out for 4" blocks)

The Bilstiens I bought are longer than the factory Ranchos and I think they would work for 2" as well. Much better shock. Most like the Fox better though...your wallet won't, but I plan on them next. I think the factory shocks would bottom out on rebound.

Do yourself a favor and get the Carli 2.5" front springs.
