iv been thinking about getting 3:90 gears but im not sure if i want them or 4:10s or 3:73s

 

Year? Model?

 

im running 3:73 in mine. 4:10 are more fun but i drive on the highway too. 3:73 is perfect for me

 

Is there really that much difference in the RPM's between 4:10's and 3:90's at highway speeds??

 

Forgot I had this link kicking around .. not sure how reliable it is but you can give it a try.

i still say get that search button highlited or in bold lettering

 

Get the 4.10's, I have them and I drive on the freeway a lot, I just cruise at about 75 or so. The rpm's will be 400 higher, so if you cruise at 80 in 5th the rpm's are usually around 2500 or so with 3.27 but they will be just under 3000 with 4.10's. Trust me, I thought a lot about the gears before I got them but I didn't regret it one bit.

 

Ive got 3.90s and im at about 3000 rpm at 95.

 

My 4:10's are pretty close too that too.

 

3:73=2400rpm at 80

 

go with 4.10's
