So if front blocks are bad, why are rear ones OK?

[dremu]

Everybody says that front blocks will pop out and go flying. I can see where that would detrimental to your suspension, nevermind the passersby.

But why don't rear blocks pop out? Is it that the rear axle isn't subject to the lateral stresses that the front is (since the front end is what turns)? ... seems like the rear axle would still see sideways pressure when twisted up in the rocks...

anyway, inquiring minds ... inquire. I didn't think this was quite COG enough but for all I know it'll end up with a subtitle of torsional stress analysis /forums/images/graemlins/laugh.gif

EDIT: While I own a pair of 4" blocks, they're currently holding down the back of the truck (ie loose in the bed) and I intend in the future to only use them to hold down other things (ie paperweights) When I get the housing squared away for me and the trucks, Karnak The Invincible sees a shackle flip in my future to go with my front lift springs (thanks DesertRat!)

you are right. Lateral pressure is a big issue, in a crawler you are right it will get plenty of lateral stress. You will never see blocks in a rig I own, hunt me down and shoot me if I ever change from that statement. I should note, don't count something I bought and plan to replace /forums/images/graemlins/wink.gif

Blocks can and do pop out of the rear suspension. It's not only lateral stress but the amount of torque applied to them. If you're considering blocks for the suspension please think about what you will be doing with your rig (street only or actually wheeling) and think about how much money you'll save by doing things right the first time. /forums/images/graemlins/thumb.gif

My DD came from the factory with rear blocks.

 

[TruckNutzDude]

I doubt it's taller than 2" though. That's the maximum safe limit IMHO. I'll be running a 2" block for my 63" rear springs IF I need it to level out with my 6" fronts.

 

[sled_dog]

you will likely need something.

I have a Superlift 2" suspension lift with blocks in the rear. What would be a good set of replacement rear springs to eliminate the need for blocks? As it is now the rear sits a little lower than the front with the blocks.

ORD sells a shackle flip kit that gives 2.5" of rear lift. No need to go with stiffer less flexy springs.

y'all that scary ford from last week that had pieces of cut leafspring being used ass lift blocks thats what I thought of when I read this thread /forums/images/graemlins/thumb.gif /forums/images/graemlins/hack.gif /forums/images/graemlins/weld.gif /forums/images/graemlins/grind.gif

[/ QUOTE ]I agree, ORD Shackle flip in either 2.5' or 4" depending on your app. is a much better choice the blocks !!!!

I go to school w/ a guy who has the stock 4" block in his dodge w/ another 3 inch block stacked on top...seems a little bit dangerous/retarded/ridiculous to me... /forums/images/graemlins/eek.gif /forums/images/graemlins/yikes.gif

 

[Resurrection_Joe]

Heh..... I ALMOST did that back in the stupider days

 

[dremu]

Oh, stacking blocks is easy... you just have to use couplers to hook the factory U-bolts to all-thread to lengthen them. /forums/images/graemlins/eek.gif

If ord uses spring center pins on its zero rates,which is practically a 1" lift block, why not use longer spring center pins on blocks of 2" or more to keep them from spitting out.

 

[m j]

exactly the problem with promoting the ORD blocks as 'safe and proper'

 

[84_Chevy_K10]

They're especially safe when used with grade two centering pins. /forums/images/graemlins/rolleyes.gif
