    Looking for a differential for my truck that has "posi" I currently have the stock "one-legger" with 3.73 gears. I would prefer 4.10's but if someone has a differential i can switch the gears. My truck is a 1999 2WD silverado 5.3. Thanks

    You dont need a new or different Differential. If you want different gears, you can change them. If you want Posi, you put it in.
    I changed my gears and went with the Detroit TrueTrac posi.
