I just purchased a 5.5" Cage suspension system w/ radius arms. I went with the long travel cage shocks. Compressed they said they were 19". I plan on upgrading to the Bilstein 9100 series shocks soon. Bilstein has a shock with more travel, but it's taller when it's compressed than the cage shocks. Can you run a taller shock than the 19" cage shock without causing any problems.
