guessing you plan on running rockwells with the ranchoro lift springs for the fullsize jeep, shouldn"t be to bad of a problem, worse case senario you weave in some j20 leaves stiffen it up a bit, the 44044 were designed for a 360 v8 and a dana 44 so yeah.
seen rockwell on a j20 so don"t see why the 44044 would be any different
