    Rear end options for 92 truck

    Hey guys,
    Just done a cammed L98 conversion to my c1500. It has a 10bolt open wheeler diff in it right now and was wondering if it is worth putting a LSD in it or replacing the whole diff?
    Car will make around 400rwhp so just trying to work out the best way to go.
    Cheers
    Brendan

    i would go with a true trac and a good set of axles amd that should be enough.

    +1 for the TrueTrac, but he prolly isn't making the power to justify new axles. Throw in the new carrier and call it good.

    Daaamn son! Land of the Kangaroos?????? Yeah, I would say that would have to suck....

    I would say to contact Ron's Machining Service on Ebay. He is 100% perfect with every order he has taken. Send him a message and ask him if he'll send one to Aussieland.

    I had a lot of trouble with the 92/93 10 bolt holding up to hard launches and had trouble making an Auburn last very long with nitrous launches. If you're staying motor only with no power adders you should be fine to put a detroit true-trac in the rear to put the power down. I wouldn't recommend the Auburn for a power adder vehicle, turbo, supercharger or nitrous.
