Aluminum Lift Block Question

[blackdiamond]

I read on another thread that aluminum lift blocks split under load?  Is this a common problem?  Does this apply to solid aluminum blocks?

I have 1.5" solid aluminum blocks ready to be installed on my truck.

just get steel ones, cheap insurance

I have broke a set in moab this year and I have a friend that broke a set too.  But they were both the hollow autozone style.  I would think that solid ones would be just fine.

I could understand the local autoparts style blocks having problems due to a cheap design.  I know that steel wheels bend and aluminum wheel crack, so I would expect that the same would apply to blocks given enough of an impact load but I doubt that a solid lift block would cause a problem.

Waiting for more opinions.

I try to stay away from blocks but I think a solid block would be fine, the hollow autozone/pepboys blocks are just for showboaters and not designed for real "offroad use"

Blocks and spring wrap go hand in hand.

I called A.O.R about 10 days ago to order their 1' aluminum pucks and they were out. So I went to a local metal shop and bought a bar of 6061 T6 Aluminum and had my own made. I pulled out a set of hollow plastic 3" pucks from 4/w Parts Wholesalers that I have wheeled on for 8 years with no problem.
When I wheel I go Beverly Hillbilly  Style. 4runner loaded to the max. Cargo thing on top loaded to the max. And a trailer fully loaded . So I dont think the aluminum ones will be any problem.
What grade of aluminum pucks do you have ?

Try Roger Brown http://www.4crawler.com/4x4/ForSale/ProductLine.shtml

He sells lift blocks and angle shims for yota's even tapered billet aluminium lift blocks.

I got mine from Roger Brown.  I'm not positive if mine are billet or not, but I would guess that they are.

Sorry Blackdiamond I guess I need to slow down and read . Not body lift, lift blocks.

If you have the solid blocks from rodger brown then ease you rworries..however do keep those u-bolts tight..If you wanted to be way slick about it have a shop weld on a u-bolt keeper plate..that way they can't spit out..

All is forgiven

Roger Brown assured me that I could set a 747 on the blocks if I could get it to balance.  I guess this means that my question is answered and nobody even tried to hijack the thread.

What shall be talk about now?
