I dunno if this has been brought up already, but can someone explain how ORD's "Zero Rate Add a leafs" (http://www.offroaddesign.com/catalog/Zero%20Rates.htm) are safe? them seem to me just to be blocks, but they bolt to the spring packs.. i would think they would still add alot of the same stresses to things like the u-bolts as regular blocks... ORD claims they are safe for the front... I just dont see them as being something very safe? Can someone explain to me how they are? thanks. Garrett

I wouldn't know if they are safe or not, but all-pro sells something close to that, but not as thick. All-Pro axle relocation plates (http://www.allprooffroad.com/relocationplates.html)

i'm pretty sure that if your cruiser is still sprung under axle these blocks will actually lower your rig.

oh brother! cant anyone build their own shit now a dayz? without calling 1-800-ALLPRO?

yep, they're a bolt on block, therefore they can't be spit out, and in theory are safe for the front...

IMO, they are less-dangerous than a "normal" front block, partly since they are bolted (which is a moot point as soon as you shear the centering pin), but also since they are made from a real chunk of steel (I think), instead of being cast aluminum, and therefore much less likely to crack in half. That said, I still would not run them and don't encourage their use in the front.

Hey now, did I say I bought them? I don't think so. I haven't bought anything from allpro yet, and don't plan on it if I can help it!

:rolleyes:

most big rigs have a similar type plate bolted in with the front spring pack, very similar, i dont know why though, anyway, they run many many miles a year with alot of weight and seem to be fine.
hey if those are steel, which they look to be, how about welding them to the spring pad??maybe that would your minds a bit.

Most big rigs also have drop beam axles in the front, too.

My M37 Hercules diesel conversion kit came with 2" solid steel blocks for the front, to keep the oil pan off the front diff. I welded them to the axle mounting pad so now they are an integral part of the housing and can't be spit out. I believe this is safe, it has 5y ears and lots of offroad miles under it. In another rig the blocks were even in a rollover (before being welded) and didn't "spit out".
That said, cast aluminum blocks in the front or in the back (especially stacked) are for the birds.

My stock '86 F350 front leaves had a 5/16" solid steel block bolted to the bottom of the spring pack. Couldn't tell you why, hardly seems worth the effort (from the factory) for 5/16" when they could have just designed the springs a tad differently to begin with.

Most big rigs also have drop beam axles in the front, too.

cool so drop beam axles eliminate side loads and sheer stresses, thats good to know, i'll get started on my drop beam axle'd 4x4 and i will only need a traction bar to run coilovers:rolleyes:
