After completing my 4.3 to 6.0 swap, I got to looking at my rearend gears. I found out they were 3.08 gears. Probably not the best for what I'm trying to do. I heard they are a highway gear. It takes off pretty well, but I think it could do much better with some different gears. I have the stock 5 speed in it, and don't want to get too low of a gearing. It's a daily driver. From what I have been reading, 3.73 or 4.10 is a choice set of gears, but they are all with automatic trans. Don't know if it would be different with manual. Any suggestions?

 

You wouldnt happen to know what Gear Ratios your 5sp is would ya?

 

not a clue, I know there were two different manual transmissions that year, one with a creeper gear, and one without. Mine is the one without.

 

3.73's would definatly be a nice improvment for a street truck, if you like racing the 1/4 then 4.10's would probably be better.

 

I'm 99% sure they didn't make anything smaller(numberically) than a 3.42 back then. Only just recently did they make trucks with 3.23's and I've never heard of a nbs truck with a 3.08 differential.

 

all you have to do is open the glove box and get the code

 

i looked in the glove box and it says gu4, which I was told is 3.08 gears.

 

Yeah that..!

 

thanks for all your inputs. Does anybody have any 3.73's in good condition they are willing to part with?

 

Would 3.42's be something to look into?
