    I just bought a diesel K5 blazer. 1982 with 58000 on rebuild, 35" super swampers TSL, lockers front and rear and power windows cd player and A/C all for only $1100. What do you guyes think...the only think I dont like is the 10 bolt rear. I will be looking into a 14 bolt very soon.

    Congratulations! Watch out if you have the 700r4 and stock drive train turning those bigger tires.

    [/ QUOTE ] Its bigger in every way, the larger tires put more strain on the driveline. Some people have problems some dont.

    Depends on how hard you wheel it, some people can survive with 37's on 1/2 ton gear, but once you start having fun with it(especially rockcrawlin') you can break 1/2 ton stuff like a toothpick...

    Factor in the amount of torque produced at very low rpm's and snapping a 10 bolt would be easy with 35's...

    14 bolts? I was thinking to go to 12 bolts ...
    The 14 bolts is not the 8 lugs axles ?(I,m also lost in the axles&gears subject...)

    yes the 14bff is an 8 lug axle, and you can find them under 1 ton trucks as well as some 3/4 tons as well. /forums/images/graemlins/pimp1.gif

    And the 12 bolts?Is not enough stronger for hard wheeling and not go to 8 lugs?
    Thanks.

    My concern is more with running 35" tires with the 700R4 with the original axle ratio, but if he has added lockers he has probably lowered the ratio. I think a stock 700R4 overheats with stock gears ( 3.08, 3.43 maybe even 3.73) and 35" tires.

    Mine does fine with stock running gear. Although I rarely put it in overdrive.
