    I have a 305 84 blazer with 10 bolts, 350 trany, a three inch body lift, and 33" muds. I want to add a four inch Suspension lift and 36x14.50 tsl's. Should i keep my 10 bolts and put 4.10 gears or find some 12 or 14 bolts. What gear ratio whould yall recomend and which axles. Thanks a lot./forums/images/graemlins/k5.gif

    <font color="green"> Dude, you probably don't even have to search past the first page of posts to find the answer to all of your questions, they've all been asked like 3 times already this week.

    That tire is awful big for 10 bolts. 4.56s would be a good ratio if you have a manual, 4.88s with an overdrive auto tranny. For the strongest most cost effective solution, find a 3/4 ton truck with a 14 bolt and a D44 with 4.10s, swap the axles under your truck and call it good. </font color>

    Like shaggy said, and to add that 12 bolt is not really an upgrade frm a 10 bolt, they pretty much can handle the same sizes stock.
    If you feel you are close to their limit jump to a 14 bolt, either the 9.5" SF or the 10.5" FFloater.

    I think everyone missed the fact that the 305 is a waste of iron as well lol.

    Some might have had good experiences with them (mine was ok, for not having any power I guess) but I can't imagine a 305 trying to turn 36" tires with 4.10 gears!

    I ran 10 bolts with 36" TSL-SX for a while, and I still run the 10 bolt front axle. I suggest that you change the rear axle to a 14 bolt full float and convert the front axle to 8 lug with 3/4 ton stuff if you want to stay cheap. The main problem with the 10 bolt rear is the c-clip axles which come out of the axle housing when the break. If you have custom wheels for your six lug stuff, shop around and find the 14 bolt 9 1/2" semi float rear in a six lug pattern.
