I'm installing a 14 bolt axle in to a 95 Chevy Tahoe 2dr
considering that the TBI 350 puts out around 200HP and I'm running 35" tires,
should I go with 4.10 or 4.56 gears ?
I'm leaning towards 4.56
What do you guys think ?

Depends what your doing, I'm have a chev pickup with about the same power, and the same size tires and the 4.10s seem to work good for me, but I have no experience with 4.56s. For offroad use I would use the 4.56s.

Use whatever ratio is in the 14 bolt. [36]

no way man, 3.41 is way too low, that's what I have now and it sucks
28:1 crawl ratio is weak
I used to have 3.73 in my previous truck and even that was too low for 35s

I assume 14bolt semi-float?
Lower your performance expectations and 3.42/3.73 will be fine. [22]

J/K... well... 4.10 is going to be really easy to find in an autowrecker. Very common in the 8-lug versions. 4.56 is a stock ratio too, but I've only come across it *once*. (V6 HD 3/4ton).

For the effort involved in a ratio change for the front axle... I'd pull a Stuckle. :D

yeah, it's a semi-float
I guess I will try to get a set of 4.56 gears and if I can't then I'll go with 4.10s
I wish I could go for SAS but it involves lots of $$$
will have to wait for a while
thanks for your input

Wait till you see what it costs for 4.56's plus install for both ends. [1c]

(unless you get special deals or something)

Is it even worth it to put a set of gears in ifs? I thought is was super pricey to do the front.

I wouldnt bother wasting money on ifs junk. I did ifs lift stock gears and diesel(no power at all) and i blew my front end up after a month.

Pure junk, I should have spent the extra $1000 or so to sas it.

Gears on the front diff are a bear. This thing has to be yarded out of the truck, split apart, install the gears. (Gotta have a knack for these as there isn't an inspection cover). put it back together, install in truck again.

Finding a pair of 4.10 geared 3/4-ton axles for SAS is cheaper than a ratio change at a shop.
