it depends on the gears you have

 

You have a series 2 carrier with 2.77 gears. The only other gear that will fit is a 3.08. With a series 3 carrier you can go up to 4.10.

More information is on my page at www.9bolt.com

BUt cant i buy gears that fit for 3.08 carrier like 4.10 gears. if i swap gears do i have to get a new install kit??

 

Nope, not with a 9 bolt. Series 2 gears fit series 2 carriers and series 3 gears fit series 3 carriers. And an install kit highly recommended with any gear swap unless you have a supply of differential parts on hand.
