before i order....i was wondering...should i go with 4.56 or 4.88 gears? reason this occured to me is i was reading a question sent by someone to Truckin' Magazine about what gears he should get for same setup as me, and they answered that 4.56 would get him back to stock performance but 4.88 will make him perform better off the line. so.....???

 

and may i ask what size tires you are running?

 

or mayb what size engine you have? 54.L or 4.6? answers those questions and someone can help you out.

 

5.4L 4X4 with 38X15.50R18

 

What kind of driving do you do?

 

mostly on road....but weekend off roading....occasional mudding....rarely ever....cause i hate having all the mud stuck up in my undercarriage and it really screws with the truck

 

Do you highway alot?

 

I meant, mostly city or highway?

 

highway....i live outside the city....but in 2 years ill be in the city...for college at georgia tech...if i get in

but alot of highway now

 

If you do a lot of highway, I'd say 4.56s and vice-versa.

 

thanks thumper. just needed to be sure....my tires come in tomorrow

 

so 4.56 what would an okay cruising speed be? 80-85?

 

I would go with 4.88's with those tires.. They are 15.5" wide which is going to KILL you. ontop of them being 38" tall.

 

how about for some 37's that are 13.50? 4.56's? What could I cruise on the high way at?

 

I'd say 75% highway or more, then stick with the 4.56's. But I'd probably go with 4.88's in any other case.
