    hey guys i attempted a ring and pinion install last weekend... but well lets not talk about that. anyways, im dropping the rear end off at a shop because we think something is wrong. did i buy the wrong gears? notice the difference between the original ring, and the new ring. the old gears are 4.10s and the new ones are 4.56s. the new ring is the one mounted on the carrier.

    also, what carrier is that? i was told it is some type of posi unit. thanks

    That is the ever popular Gov-bomb:D . What axle did it come out of? What did you buy gears for? The carrier break on 10 and 12 bolts is so high that the gears should be close on thickness. What happened with the install some insight might help us figure out your problem.

    I see you have a 12 bolt rear. Did you order gears for a truck 12 bolt or a car 12 bolt?

    Did you try these in the housing? What was the problem with the install. It does not appear that the gears where spun at all if that is gear paint.

    The carrier break for a 12bolt is 3.73 and numerically higher, you definitely didn't need thick gears.

    The carrier break for a 12 bolt truck is 2.73, 3.07-3.42, and 3.73-4.56. Based on that you would not need a thick set of gears. The gears you bought most likely were for the 3.07-3.42 carrier.

    well a carrier is cheaper than new gears right? does anyone know where i can get a carrier that will fit these gears?


    or could i bring the old ring and this ring to a machine shop, and have him machine them to the same thickness?

    For a carrier I would call up Randy's ring and pinion or Drivetrain Specialists. They should be able to get you an open carrier relatively cheap. In my opinion open is better than a gov-bomb anyday. I also would not take anything off of the gear as it would damage the heat treating of it and could cause it to fail later on down the road.

    Why are you changing out your 4:10's to the 4:56's? I'm thinking about putting 4:10 in my Blazer and wanted to find out why you changing? Are you going to get rid of your 4:10's?

    i actually destroyed the 4.10s, the pinion blew up in my diff last week. i chose 4.56s because i have a th350 and the rpms are high on the freeway, and i dont have a lot of power around town. i figured it gets such bad mileage anyways, so ill put lower gears and scoot around town faster. if i took highways more i would go to 3.73s. 4.10s are really the worst of both worlds to me.
