    Your 88 probably has 10 bolt axle in the front and rear. You can get air locker for both. You dont have to have a Full floating axle although they are stronger.

    By the way, what is a K5 GT Gran Touring? Is that similar to the US Silverado?

    So the ARB air-lockers can take on C-clip locked axles?

    And for the Grand GT Part. The full title of my rig is a Chevrolet K5 Grand GT Blazer Silverado. The Grand GT is an extremely rare version. Heard of only 250 made. I'm not really sure about that number. It is fully american as the K5 was never sold in europe. So, no, it is not an european name. The Grand GT is in fact so rare that even the current staff anywhere within GM never heard of it. I also do not know what the all special options are but it came with a 480HP (in normal rpms) 350, higher suspentions, old style head lights (above eachother on a 1988 blazer is not standard as far as I know, should be next to eachother), one hell of a small steeringwheel and a gov-lock rear axle (Will that be a problem installing ARB's?).

    So that is the grand GT story. Could say I'm proud to have been able to snug this baby out of the US from under your noses. But don't hate me for it, I take perfect care of it. I feel it is better of with me than some dessert racing, jeep loving, rough riding freak that will kill it within a year.

    Yes they do make ARB's for C-Clip axles.. The ARB will replace you entire carrier like a Detroit locker. If you do serious wheelin and have tires larger than 33's or 35's, then you may want to upgrade axles beofre you dump that kind of cash into your stock ones.
    The ultimate axles would be Dana 60 front and 14FF or Dana 60 rear....

    Depends on how you wheel though.

    From your description of how you take care of it, it sounds as if you may not wheel that much so your 10 bolts will probably hold up.

    I'll have to keep my eyes and earsopen for info about the Grand GT version, sounds cool!

    Wow, that Grand GT sounds cool!! 480HP...that's like double the normal 350s.

    Anyways, no ARB for the 14bolt FF rear. So, you will have to go Dana 70 or 60 rear for ARB.

    axles are as easy to get here as 10.000HP engines. In other words, near impossible. Though I have 35x14.5x15 tires ready to be installed.

    Well, it didn't hit until now, but like Boss said they dont make an ARB for the 14FF.
    With 35's, high HP and sand, you may want to step up in axle strength.... I know you said they are hard to find, but it would be better than changing broken parts all the time.

    What usually breaks on a 10 bolt:

    Axleshafts
    Carrier
    Ring and pinion


    You could make you 10 bolt stronger by adding:

    Aftermarket Cromoly/alloy axleshafts
    Aftermarket Ring and Pinion(Richmond)
    Axle truss
    Diff cover with carrier support

    And since you are planning ot add an ARB, that will replace your factory carrier with a stronger unit.

    A full floater kit might be a good idea in the rear, otherwise a good set of 30 spline replacement axleshafts would be wise. You might truss the housing also. Under sane use with a smallish tire (33 or 35) you should be fine.

    i have an arb in both front and rear of the "blue ox" and i absolutly love them!! but i frequent moab and have broke the side gears twice. arb is way cool and always send me new ones even tho im out of the warranty which is 31 inch tires. i have been running 33" bfg's. anyway what breaks is the side gears in mine. i have the 30 spline axles.

    i now have some 35 swampers so i bought a 14 bolt sf and they do make a arb for that..... i would get rid of the old 10 bolt brakes axle arb and all for $500.00 it has 3.73 gears.

    anyway there ya go

    ken with the "blue ox"
