Don't forget the performance stickers such as Summit and Jeg's and the like.

Also, lots and lots of chrome. That makes everything faster.

 

ok so I guess I will regear I think I will do the rear myself and the shop can do the front. another question is I know I need a ring and pinion and an install kit anything else and are there any special tools I need?

 

Precision measuring tools. Gear setup is touchy.

 

ya I will attempt it. I think my rpm is around 2k at 120km/h I would like that to be up a little going up a small incline it needs to shift down to keep speed I don't know if I should go with the 4.10 or 4.56 now

 

4.10 and 33" tires will have your RPM right around where they generally are with stock size tires/gears. 4.56 will bump you up a couple hundred from stock at freeway speeds, in O/D. Really not much of a change, but, my guess is, gas mileage will suffer a bit on the freeway, but, you will have MUCH better low-end grunt. Should be able to pull the house off the foundation with the right tires.

 

does anyone have the same setup 33" tires with 4.56 gears to see what there rpm are at I would hate to put 4.56 gears in and have them be to much and put my rpms to high

 

Here is an online calculator. (all the way on the bottom.)

O/D Ratio is .69
T-case ratio is 1

With 33 inch tires, and 3.55 gears, 60 mph is just under 1500 RPM.
Same tires with 4.10 gears is 1730 RPM
with 4.56 gears is about 1925

In my opinion, 1500 is just too low. The engine is lugging trying to hold speed, even a slight hill will make it downshift.

1700 or so is actually pretty good.

1925 might be a bit high. You would be running about 2500 RPM at 75 MPH.

 

I'd think 4.56 would be a bit much if you do a fair amount of highway driving.

 

ya I guess so what about 4.27 anyone running those?

 

Are those even available?
