i am going to put a set of 3.73's in my rear end, i called around and they all say that i need to buy a install set that comes with all the new part to go in. I just what to make sure this is necessary and not a waste of money. they quoted me at i think 125 dollars for the install kit.

 

yup, they are right, youll need an installation kit to replace all those old shims, bearings, etc., here is the kit that i bought
summit part number: RAT-3001K

 

Thanks man, i figured that was a stupid question. i found somewhere where i can get it all done with everything for a little over 400 dollars.
