What is your current gearing?



Are you sure you're up for changing front and back diff's?


Usually can't go wrong with 4.11's, but if you do alot of offroad crawling, you might consider going into the 5's....

 

 

If you are going to be pulling alot, I'd definitely go with the 4.11 gearing. But you'll have to change both differentials if you've got 4x4. I'm not sure if that was a option for this era of trucks. If not, you'll have to buy the gearsets and have them installed.



You can do it yourself, but unless you are practiced at it, I suggest you have a shop do it.
