95 tahoe k1500 diésel axle gear for 33s

[Fedeleon1]

Hello, I have a 95 2 door Tahoe k1500

It has a 10 bolts open diff
I am running 33s tires

I am planning into doing some towing and also want the truck to be stronger and to have posi axle

Right now my truck accelerates kinda slow until it reaches 2k rpm

I want to know the actual gearing in my truck so I can decide what gear I want

I was thinking into 4.10 or 4.56, what do you think?

It has the Detroit 6.5 in it?

Looks really nice btw. Should be able to check what gear ratio is in it now by looking up the VIN or RPO codes.

Yes, 6.5, I check and I think it has 3.73

If you plan to stay with 33s 4.10s might be a good choice but the difference might not be super noticeable. If you ever plan to do bigger tires then go 4.56s for sure.

I am with @Dantheman1540 on this one. A 4.10 gear should do it for you. 4.56 would be a bit steep. I would have thought that the 3.73 was good as well. But the 4.10 gear will give a better start from a stop for you.
