Rear Gear Questions

I want to regear my 5 lug. It's a 2011 with the automatic. I'm running 31's right now but am going to up it to 33's pretty soon.

What final drive ratio do I have?
Who sells rear gears for my truck?

 

i believe you ave 3.73 for 33s you would probably need 4.56 you can get them from east coast gear supply

 

4.56's?

That pretty damn low. I'm just wondering how did you come up with that number?

 

most guys run that for 33s. 4.10 for 31 4.56 for 33 and 4.88 for 35

 

Even for street driving? Do they have 5 speeds or are they 4 speeds like mine?

 

I would contact ecgs first. See what they recommend for your truck. But i think 4.10 isnt enough for 33s

 

stock 4cyl 2nd gens have either 3.10 or 3.30 gears so i say 4.10 or 4.33 would be better

 

Your rear gear is a 3.58 with the auto tranny, the manual tranny is a 3.31. If you want a stock power feel then go for the 4.10 as previously stated, more power go with the 4.56.

 

I'm also considering re-gearing. What is the trade of on getting 4.56 over 4.10's?

 

If you go with 4.10 you might see an increase in fuel mileage and a definite increase in power. With a 5 speed, 285/60/18 and 4.10 your RPM at 65 will be about 2200 to 2300, same setup auto trans RPM will be around 1900 to 2000. With the 4.56 you will see a power increase and the MPG could stay about the same or decrease. Same above setup 4.56 5 speed RPM will be around 2500 to 2600 and the auto would be around 2200 to 2300.
