Talked to MC the other day, apparently you can go with Fox 2.5 DSC shocks listed for a 4.5-6" lift. They more closely match the extend and compress specifications for their Rocksport shocks. I went with the front ending in 052 and the rear ending in 056, which where in stock. I'm also getting thenm from Accutune to get them dialed in for the 392 with all the aftermarket stuff loaded on.
