Yes they do come mostly with 3.23 and 3.42 but Tib is talking apples to apples. Same mods or both stock. Sometimes even the 02-04 with less mods will out run the 05.

 

Actually they are 3.42 for 4x4 models

 

hey blue ur talking bout a lot more weight , , 3.23's one wheel peeler and just a flow and it runs a 16 flat thats pretty good i hit a 15.9 with a str8 3 inch pipe and a 3.73 ecsb

 

what could be different , all they changed was the eletric fans , maybe the tunes on them . i heard 05's come with a thing in them to where the govenment czn shut ur vechile down if they have ur tag number and stuff . which IF thats true they must have changed the comp . and god my typings bad lol im gettin use to the laptop

 

In my one track visit, I ran a 15.40 in high 70s weather with magnaflow muffler, upd, conservative tune, and 3.23s in my ECSB on stock wheels.

 

i guess it all depends on how you break them in...

 

i will say that from what i've seen in the 05's that i've programmed they have seriously softened the programming up.

 

good thing I"m stuck doing appearance mods
