Depends on how you do it. I had my entire diff swapped for one with the 3.91 gears installed. which is typically $3000+. If you find a shop you trust, you can buy the gears for $700 or so and have your diff rebuilt for another $800 or so - half the price, but you're without your car longer and the shop has to know what they're doing.
