well if you window sticker says 4.10s and you dont have them then i would take the truck back and demand a full refund :crazy:
look in the glove box. GT4 is 3.73, so if you dont have that they you have the 4.10s :head:
as for the warranty, yes a lift will void all suspension warranty. it may or may not void all steering warranty, some people have no trouble with dealers in this aspect. the dealer would find it VERY difficult to void your engine warranty or transfer case warranty. rear end, front diff, and tranny for sure can be voided.
the reason that one dealer warranty's those trucks is because they installed everything them selves :read:
now you could probably sue them for refusing yours when you have the same modifications and they refuse you for getting stuff installed elseware :crazy:
