    Default what rear diff gears should i put

    Ok I have a 07 silverado single cab with a 4.8 and I just blew out the gears in it. It had 3 23 gears now I can't decide between 3 53 with posi or 3 73 with posi.

    What do you do with your truck, does it tow a lot, highway driving, city streets? Is it a 4x4 with larger tires? If so what size?
    A little more info will get you a more informed answer that'll help solve your dilemma.
