Yeah...you need at least 4.10's. Axle swaps is cheapest.

my first suggestion is a K&N cold air intake, it'll improve your gas mileage and give you a few more horsepower.....

Yeah....front and rear axle swaps with junkyard 4.10 axles is cheapest when compared to gear swapping your existing axles. Gear swapping can be $1200. Axle swapping can be $400 tops. If you plan on bigger tires down the road, swap to 4.56 gears. Better and smarter for the long run.

It's a truck you are not supposed to be racing right???? ask him to join for a small/slow ride on a mud pit..... then drink a beer while seeing his caravan slowly sink in the mud...

can't get 4.56 stock....4.10 is the deepest from a junkyard axle.

Check out the gear ratio sticky.

Then gear swap it to 4.56....rpms on highway will be higher, but the truck will be far more drivable. And 4.56 is minimum needed for 35's.

Again, check out the stickied ratio chart.
