95 yukon gear ratio change

[oohunter04oo]

try and find 4.30s

You won't find 4.30's for the front diff.



I had 4.56. With 33's, 35's an 37's. it was definitely the best with 33's. sorry I don't remember any of the rpm's but I don't run it down the interstate that often. But around down driving I loved it with the 33's.

With my 31" tires 4.11 work just peachy with my interstate towing 2050rpm at 65mph

since it is a couple more weeks in, how are you feeling about the ratio now?

Did you indeed have 3.73s in your truck? The RPO code in the glove box for 3.73s is GT4.

4.11 if you are set on doin the swap honestly just go to a junkyard and find a sf 14 bolt with stock 4.10s they will last forever and have igger drums for stopping power on large tires

Sorry I made a mistake 305/55/20 is just shy of 33" tire and I love the change..brand new gears front and rear new wheel bearings seals everything... I didn't realize how quiet this truck really is now ..Havnt got my final mpg numbers get but ill bet I got a small improvement! An for pulling it made a defiant improvement no doubt at all... Yes they were 3.73 and I swapped to 4.11 which was perfect for what I needed...my friend has a 99 zr2 and we did a best of 3 drag race and I could just barely walk away from him with the 3.73 and with the 4.11 my truck runs away from him now so my friend is looking to get Into 4.56's for his truck now since he has 4.10 now lol..

Very happy I went with 4.11 instead of 4,56's
