no I dont care im not sure why you seem to think i do simply because i put 'EDIT' but i do that 90% of the time when i edit a post... anyways im sure your minds set that i really did care, but in reality i said that so that you wouldnt try to explain what it meant because i really do not care what you or anyone else on this site thinks of me.

yea youve deffintally hurt my feelings








I guess your one of the ones who got really butt hurt over something stupid and now that someone else mentioned the section and you feel like you have backup your gonna stand up to the big bad '4x4 section internet bullies'

but if it makes you feel better you can continue to think you've hurt my feelings because 'the tables are turned a little and i cant handle it'

 

Um , I think this may be a good example of the problem ...I know you apologized , but posting anything that makes you look like an expert , over and above anyone else, makes "you " look like a fool ..

Tell me , from your (no one else s'"stories" )own experiences ,about your own personal block failures .

The front has a track bar for a reason ..

Spring lift , shackle lift , block lift all face the same forces ...The center of gravity changes ...Explain to me what I am missing & why you are an expert on the subject ...

 

Good grief ...

 

so you run a front block?





I could explain why they suck, but your arrogance and the fact that you think the trac bar has anything to do with a block says it won't change your mind anyway.

 

LOL ...I don't ... But If I feel inclined to , I wouldn't be too concerned (Except for drive shaft angle ) .. .

Why don't you educate me ...

You are right about 1 thing ,, my arrogance..

You seem to have Information that defies physics ...

 

Please , change my mind..... after lateral loads are handled , what is left to be concerned about ?

 

I would think that blocks by themselves aren't a good idea. But, as Rick said, with added supports to stabilize the blocks and axles, it should be fine. I'm not an off-roader anyway, but I have seen some guys that put blocks under their springs without any other support structure that look scarey.

 

well the fact that they are illegal for safety purposes should concern you...

 

Rick, have you ever seen a lift block come out ?
i have, and it went through the windshield of a passing car, killing the passenger in the front seat while her 2 small children watched from the back seat.

the blocks were just "professionally installed" 4 days earlier.

i have also seen the aftermath of a front lift block failure.
luckily the only one killed from that one was the driver after he lost control and hit a tree head on.
the truck also had a body lift on it that looked like stacked hockey pucks. the bolts sheared on contact with the tree, and the body separated from the frame.

there are reasons things are illegal for on road use.

 

I don't know anything about 4WD modifications, lift blocks, or any of that crap. I'm not too interested in anything more extreme than what ever a good factory 4WD can do. That being said, common sense tells me that when you start modifying anything critical to the stability of a 2-3 ton vehicle beyond what the manufacturers found to be necessary and safe, everything is suspect from a safety standpoint. So when those who have passion for it tell me it's not a good idea, me personally, I'm gonna take it into consideration.

 

Nice response Tom. However I fear it will fall on deaf ears. His arrogance and denial of what is legal and safe for ON ROAD USE is the prime example of why we get labeled as a "bunch of jerks that only want to bash new people". The simple ignorance in the belief that a track bar will keep front lift blocks in place and claim it's "simple physics" makes me want to bang my head against a wall.

Action, with the addition of really tall lift blocks, or the stacking of blocks as I've seen, causes a cantilever effect which will make the leaf springs wrap up into "S" shapes when torque is applied. When the springs try to return to their original arch shape they try to throw the block out of the rear with some force (as Tom mentioned where it threw the block into the windshield of the car behind it!) making it a death seeking projectile. There are blocks that have retention systems to keep them in place, but again is still a minor fix where the proper lift spring is a much better solution for a lifted truck. The same happens when a block is put iin the front, but the stresses are increased with the added weight of the engine directly above. I have seen blocks crack and fall apart prior to being spit into the floor board and engine block from someone doing this. Luckily only the truck was harmed in that case. Do I need to continue on as to why putting blocks in the front or really tall (taller than the 2" STOCK blocks) in the rear, or do you want to keep up your smart **** attitude and cry about how all the members of the offroad forum are big meanie heads?

 

Tom and Karl gave a good example of block failure (Tom), and the reasons why a block lift is unsafe (Karl). I have seen 6" blocks under the rear springs with nothing else to support the axle. That does look scary. I've never seen a block failure, but I do see how it can happen.

 

I completely understand the logic ,as far as the blocks go . In The case of the block failures Tom spoke of , Does anyone Know what the reason was for the failures ? Pro's screw stuff up all the time ...
I know people can do some very strange things . I had a guy show up one day with his Venture in a trailer , & the tongue of the trailer was duct taped to his hitch (no ball )..

I have a factory set up with 4 " blocks that came on the truck in the rear, & re- curved (when the springs were brand new) & an add -a leaf on the front ,to carry my plow .

The rears are a 6 stack & still there is a bit of wrap ..


As I said ,I don't need them . This whole thing for me was about attitude's..

 

I can guarantee you that no ford came with 4" factory blocks. More like someone added them in at your request if you bought the truck new. But nice try. Mis-information being spewed out over the interwebs portrayed as truth is part of why we act harshly to some people.

And as for no axle wrap, unless you have some type of ladder bar setup bolted directly to your axle tubes, I'll bet you the title for that truck you have axle wrap when using the factory leaf springs and those 4" blocks. You just don't know it....

 

Take a look at the rear blocks on an F350 Super Duty some time.
