Opinions on Re Gearing

[Dozerdog74]

Im wanting to re gear my truck to make it better for pulling. I am currently on stock gears (3.73) and dont feel I am loading my motor to its full potential (695 hp). I still use the truck on the farm when pulling season is over. Im running 305/65/17 all the way around with duals on the back. Going down the track Im running 30 psi of boost, 1560 +/- EGTs and 26k rail pressure. When the pan hits me my boost jumps to 38 +/- psi
Everyone around here is running 4.56 gears and shifting to 4th but most of them pull only. I also have heard of guys running 3.42 and staying in 3rd.
Thanks for the input.

Maybe try 35s? What gear do you run?

I run 3rd gear, low range. I only have 5 hooks on the 6 BFG's,,lol. I hate to sell them already.

I think 4.56 is too much for a dd unless your on 35"+ tires. I would do 4.10's to help and stay in 3rd since it's what dually a run

Go to 3.42's and stay in 3rd gear. Will still be plenty drivable.

What is your ground speed with current setup?

Go to 3.42's and stay in 3rd gear. Will still be plenty drivable.

This is ur best option.

If I towed I would have went to 4.56. I went to 3.42 because I want to hit up the drag strip and pulling track the next weekend. The 3.42 will lug the engine and I have twins with a 1055 and its still laggy. Don't get me wrong you can still tow with 3.42 I just wouldn't like it.

BTW my truck should have came from the factory with 3.42. Best change I have made to date.
