4:27 or 4:56

[chevy4x4]

I have a 78 blazer wich i want to lift 7 inches.
I would like to run 38s but am probably going to run 35s first. Should i get 4:27 gears or 4:56?
I don t want my gas mileage to be "too" bad/

p.s. why does it say stranger beside my name?

If you are running 35's than 4.56:1's is the ratio you want. If 38's are in the future, than you may as well put in the larger gears now. I think its 5.11:1? Don't hold me to that though.

As far as stranger, well its just the computers way of letting us know that you are "stranger" than the rest of us.

I would go with the 5:11s might as well, why spend twice if 38s are in your future.

keep blazin !!!

4.27s are not available for GM axles (only Dana 44s). 5.11s are also not available...try 5.13s.

I run 4.56's and seems to be fine for me a little high geared but nice when on the freeway in between trails. I almost went 4.88's they would be ideal....

Here is what I say works:
4.11 for 33's
4.56 for 35's
4.88 for 38's

And not only does the tyre size matter with the gears, it's also which trans you have... you could go with a higher gear (4.11's or 4.56's) than 5.13's if you have a lower first gear like the 700r4's 3.06 first gear compared to the TH350's 2.52... and what kind of driving you're doing. Hoped that wasn't too confusing...

NEVER been stuck... *yet*
