im really thinking about changing to a limited slip and changing the gears while its all out. anybody know a good ratio to go with on a LSD?

 

I would look at 3:23, 3:55, and 3:73. The 3:23s will give you the best fuel economy while the 3:73s will give you more off the line pull. I myself would go with the 3:55s as they will give you a little of both. But maybe you are thinking more on the line of 4:11s which is fine too. It is up to you.
Good luck with your choice.

Also look to see what gears you have now. They may be what you are looking for.

no deffinately not. it has 2.73 open diff in it right now. im havin trouble finding some good 3.23s or 3.55s so maybe 3.73 with a limited slip would be a nice change hopefully that will all hold in the stock 10 bolt.

 

yea i have an 87 and the rear diff blows. i was thinking ab geting 3.23s but i might go with the 3.55s. let me know which one you like better.

 

i'd go with 3.73 or something around there at least... i have 3.42's and its geared too high for my liking...

 

What size tires are you planning on running? If you want speed off the line and are running stock tires, 4.10. A good compromise for all around is 3.42, and then numerically lower to save fuel.

 

stock tires for now, if i ever upgrade itll only be by an inch or two

 

What is stock on your truck.
