looking at your sig and by your name, you have a 2006 and 1996, if it is in the 06 then yes you would probably wont upgraded hydralics because with in time, they will go out, but if it is on the 96 then you are fine runnig the stock hydralics they were built alot better back in the late 90's then they are now, and I run those hydralics on trucks with 4200# with no problems at all. I know its the 6.7 forum but just going off your sig etc.
