My truck makes no sense

I've been fooling around on this website and no number for rpm and mph match
http://www.grimmjeeper.com/gears.html

 

Looks like I'm going to have to see what gears I have my rpo says I have 3.42 but if I put a 3.73 gear ratio in on that web site it basic matchs my rpm at a few different mph

 

I have 4.10's and 33's... RPM's are back very close to stock, but it still feels a little bit sluggish with the added weight from the tires (compared to stock tires and 3.42's). My BFG's are load range D, so they may be a little heavier than the average tire.

If i ever change gears in the future it will be to 4.30 or 4.56.

 

hey km346 like your blazer reminds me of my old one

 

heres my blazer as it sits now

 

 

Some nice rides. Im gettin jealous:-)

 

Thanks lol so today I'm suppose to be getting a call from ord about there kit it's suppose to be there first new wave and if sales are good they might continue

 

ok so I have a 3.42 gear ratio found out by spinning the wheel and counting the driveshaft spins ..... im scared putting a 3.73 will have me reving to high on the highway ...

so the game plan is to just not touch anything lol and see how it drives I don't plan on having a driveshaft for the front being made right away so ill have time to see how the truck drives

 

Thanks man! I distinctly remember a video of your old truck on youtube trying to climb a snowbank in 2wd. Lol
