Which Gears For my Truck
O.K. people I need opinions on what will be the best gear ratio for my Sierra. I do a lot of driving on the freeway, and it's a DD. Pleas keep that in mind. I am also down the road going to swap in a 6.0 lq9 engine.
I am thinking 3.90 or 4.10

Bigger is better in Texas, except the women, California just follows what Texas does. I say 4.10

Well it's looking like 4.10 is kicking butt! I was going to go 3.73 that's on my list of things to do, but my truck is a gu6 3.42 as of now in stock form...
