I have a 2007 flareside 4x4 with a 6 inch procomp lift with 35 inch wheels. Now i want to go with a 3 inch body lift and want to go with 37 or 38 inch wheels. I asked the guy at the shop that does the work and asked him if it need to be re-geared and he said that I didnt. I have 373 gears. i would like to know if anyone has gone with this set up and did you have to re-gear. Any help will be greatly appreciated.

 

Some say that you don't, But you will burn up your tranny and your truck will be a dog....Save money and regear

 

Yeah, you are gonna want to regear with 37's.

 

Dude, when you ask me a question im not gonna steer you wrong? I told you that re-gearing is going to be your best bet!

 

I'd regear. 4.56 if you want better mpg. 4.88 if you want more power. Good Luck!!

 

You would be foolish not to re-gear.

 

Yep...definitely regear!

I would go 4.56
