in theory yes. if the rear portion of the lift uses anything other than shackles to gain the lift in the rear. i cant remember what the rancho uses for the rear lift. the front will lower your control arms. you can get reindexed torsion keys and get the torsion lift. like i said theough, as long as the rancho lift uses something other than shackles to lift the rear, then you can so the shackle lift in the rear also.
hum, ill have to figure out what rancho uses to lift the back....I may not go with it anyways because it was almost $2500 installed. That is alot of money for a truck that has 115k on it and cant resale for more than $5k.
I think I'll just go with the body lift. Shop will do it for $800 total.
