Anyone using them? I have a 3" set and was thinking about using them. They are solid in construction and I am told that they are aircraft grade alluminum. I am a little concerned but considering using them. Everyone says they break but has anyone on here actually broken one??? I have seen broken cast blocks but only because they ubolts came loose....They are Procomp who of course assured me they would not break or slip out...

 

I couldn't imagine what it would take to break those. If you got them already might as well use them.

 

There procomp nuff said. procomp wouldent make garbage

 

I agree. I just read a few posts about aluminum blocks corroding between steel springs and steel axle due to indifferent metals. They are 6061 aircraft grade....I can't imagine they would corrode either but who knows...

I got them for free and installed a add-a-leaf so that I could use a smaller block due to axle wrap....Think that I am going to try them...

 

another note on the corrosion arguement, we have been putting aluminum wheels on steel lugs, steel lug nuts and up against steel brake hubs for years with little or no corrosion. So why is this a concern on this site????

 

Honestly, I don't see how corrosion would be that big of a factor. Especially being in Florida.

 

I don't either but I tend to over anylize everything. I am just reading other posts in the search. I don't think that corrosion would be a factor in any environment but that is just me. Again the wheel arguement, we put aluminum wheels on steel studs, with steel lugs up against steel brake discs/drums and never have any problems. I am a little concerned about breaking the block and such but not that much...

I just assumed that this add-a-leaf would settle a little bit but it has not at all so I am considering a smaller block. Better for axle wrap anyways though....

 

Its gonna take alooooong time for you to notice that aal sagging. Plus its always better to go with a smaller block than a big one to achieve the height you want. maybe you can sell the 3 inchers or something? But if you decide to use them they are definitely a great quality and should feel confident in using them.

 

Chances are if you can manage to break that block, your gonna have a lot more serious problems to worry about. It's gonna take a lot of force to actually break one of those, and you'd probably break something else before the blocks. I'd run them and not even worry about it.

 

i have ran alluminum blocks from AUTOZONE in both my 98 2wd and my 01 4x4. as long as the bolts are tight you will be fine. I would check the nuts once after a week or so then be done with it.

 

Yea that stuff is strong

 

any corrosion???? I am sure that it would take pretty much the life of the truck for it to corrode but it seems to be a topic on this site as well as others, Electrolisis and such...

 

I might have jumped my 97 over a field entrance while looking for my phone after a golf tournament. I actually broke the nub off of the block and bent the bolts. I also cracked a wheel. It was not gentle. I had to replace the bolts and block. If you get to the point of breaking one, something is going to break anyway. Just my opinion

 

I wouldn't imagine any more corrosion than what you'd see on the cast blocks, maybe some surface rust and very minor pitting, but I'm sure they'll outlast the life of the truck.

 

I painted my blocks with rustoleum when i painted my axle. You could do that to protect them
