rearend 3:23 to 3:73

[skeet]

got the rearend and a friend wants to buy it, gonna sell it to him for what it will cost for a auburn or eaton differential would cost, but i am trying to find out how i can find out my spline count someone mentioned about some number in the glove box if this is the case which number would it be... a good sample would help me figure it out ...

[RedHeartbeat]

30 splines if its a 10 bolt rear end.

you make it to easy red lol but thanks again as always !!!! so what would you prefer auburn or eaton...

[RedHeartbeat]

I like Auburns. My personal preference but the others may be better. Jegs sells them for $408.

Congrats, you'll love the new found traction.

good job! build it right. red has become increasingly helpful to me cuz he has explained that there is no reason to add power to an engine if u cant transfer it to the ground efficiently. thats why on of my next mods is going to be a new rearend with 3:73's. i just ran into a helluva deal on a few other things so again my plans have changed. also need to get the truck running correctly before anything else. i think im going to do that tomorrow after work.

ok one more question before i order these i see like 7.5 7.6 and or 8.5 8.6 now i need to find out exactually which one i need ....

[RedHeartbeat]

88-2006 chevy fullsize trucks, 1/2 ton, have 8.5" rear ends. If you can afford it, buy the pro-series model. Its 542052, I think. Another $80.

109-542052 <----- looks like a good part number to you? hope so cause i just ordered it
