I need yal's opinion.............I tow my pop up travel trailer behind my 05 4.8L Silverado. The problem is, the truck came with 3.23 gearing so it makes getting the trailer moving a little tough. SO instead of trying to makeup the low end with bolt on mods, I was thinking maybe an eaton locking posi along with some 4.10's would get the job done............along with giving me a lil more pep off the line. Your opinions are appreciated.

 

Gas mileage is not an issue. I live in Brenham, TX and driving across town takes all of 5 min. And to and from work is about a 2 miles round trip!

 

That 4.8 would love a 4.10. Might be a bit much if you have shorter tires though.

 

my truck came with the factory 17's.............i always thought those were tall tires considering they came from the factory.......correct me if im wrong or if the tires are too short?

 

P245/70R17-108S BWALS is the tire size on the build sheet......

 

oh and whats a good price for the insteall of the posi and gears at the same?

 

The 4.10s should be fine with that size tire make sure you do the Eaton you wont be happywith the factory G80 as far as the install I am not sure what they will charge you maybe 400.$ or so for labor.

 

400 for labor is about right

 

With thise tires deffinetly a 4.10.

 

I second that
