    I would get the cast iron ones at least. I broke two sets and the third I busted the pin out of it. Got cast blocks and never had any more troubles.

    Most of the aluminum blocks I have seen are for lowering, not lifting. I wouldn't use them.

    Go with 3" steel blocks, they will be fine.

    sounds like a bad idea then. Would it be ok to drive on it for a couple weeks with easy driving ya think? or are they gonna crack as soon as i hit a pot hole?

    all depends on the grade/type of Aluminum... some of them are PLENTY strong for this application and many others are not. If you know what its made of (specifically) it'd be easier to make an informed decision. If "its aluminum" is all you can find out about it, I'd recommend using steel ones instead...

    Agreed, blocks made out of T606 grade would probably be the most desirable, for aluminum blocks anyway. As far as just using them for a few weeks....regardless of their grade I don't see a problem with that. Especially with a 3" block. Just keep your eye on them for cracking but most importantly, don't let a couple of weeks turn into a couple of months...then a couple of years.... If you plan on using them for a couple of weeks to get by then do it....but only for a couple of weeks. Unless they are a top quality, premium aluminum like T606.
