aloha from the big island of hawaii, quick question for all you silverado people on here......i am getting ready to install a 6" procomp lift on my crew cab 05 silverado with the 5.3L and i have the auto-trac on my ride. the instructions state to get a new front drive shaft.....my question is do i need this??? i have talked to my local 4x4 shop and they said not really, its just procomp recommends it because of a "chance" of binding with hard right/left turns.....does this sound right?? i really did not want to but the almost $500 shaft if i did not need it...
any thoughts or suggestions??? mahalo and aloha!!!

 

oops ment to type in "buy the almost $500 part".....too many mai tai's lol

 

come on i know one of you must know the answer to this.....

 

i'm not definitely sure on this but i know three people with 6" suspension lifts on a truck like that and none of them have new front driveshafts... i think its more of a recommendation for "just in case." kinda like running 33's on a 6" when you can get them stock lol

again though, im not sure, so dont blame me if you break it lol

 

thanks for the input, i am guessing that if something did break it would probably be in the transfer case...or would it just bust a u-joint?? any thoughts.....

 

if i had to guess it would be a u joint failure

 

I have the Pro Comp 6" on my 04 and didnt replace and driveshaft. Its been like 3 yrs and no problems.
