Cognito dual shock does work with the Rancho or Fabtech lift. I inquired with Cognito because I wanted their control arms but the said the arms would lift the front about 2" and my Rancho dual shock would have to come off.
If you found a Rancho dual shock scoop it up. I installed mine in the driveway. It took about 3-4 hours. I also added a 3rd shock in the stock location because the truck handles completely different with the dual shock and I didnt like it and wore out some frontend part prematurely. The 3rd shock I put in is a Rancho 9000xl adjustable I leave it on #1 setting just to take some of the bounce out of the dual Rancho 5000 shocks. It also makes it handle like it did prior to the dual shock. It is alittle stiffer but it handles awesome onroad and offroad.
