Why can't you run lift blocks on the front?

I don't understand why you even replied in the first place, I asked a question and you had no answer to my question..
Hopefully someone else will see this post, understand my question and reply... Feel free to reply with some other waste of time response, I'm sure you can't help yourself..

This is a re-post of the one above your 1st post. (post #14) It answers your question.
There is wayy too much flexing going on in the front suspension of a truck to EVER put blocks in the front. If it's money that is the issue, do an add a leaf, that's about the cheapest safe mod you can do to raise the front, probably the next cheapest is spring hangers, this will retain the factory ride and no other mods are required unless you go over 3 inches, then you'll need an adjustable track bar, and possibly a drop pitman arm. But blocks in the front is EXTREMELY UNSAFE.....don't do it please!!! Just save your money for a bit.

You came here posting some incoherent drivel (see above) then made a comment about Trump. I made a joke about it.
Putting blocks in the front is absolutely stupid as proven in the many posts above.

Because the loads and force angles are different on the rear springs than they are on the front springs. The front end takes more of the lateral forces during turning/cornering, and take much more of the braking forces during normal/hard stops.
Back in the 70's, when lifted mall crawlers first became a "thing", many guys put blocks under their front springs. I have seen in person, and in 4x4 magazines, many occurrences of lifted trucks falling off their front blocks. Sometimes this was due to cornering "too hard" for the front end, sometimes this was due to slamming on the brakes, and the blocks falling off forward, and sometimes it was due to hitting a pothole or rock on one side or the other.
I was "into" 4x4's/off roading pretty heavily back then, so I was subscribed to several off road magazines, and a member of a rather large off road club. There were many tech articles and reports on front end failures due to blocks being placed under front ends.
I'm not sure when it became illegal to put blocks under front springs, but by about mid-80's, you just didn't see them any more. This is for a good reason, they are dangerous as hell. I wouldn't drive a rig down my own driveway with front blocks under the springs.

Sounds like ynoteh is a Killary supporter so the question is understandable.
Norma, the side load effects between the front and rear are completely different due to the steering and braking. Though blocks are not good in most any situation they are somewhat acceptable in the rear unless the vehicle is used hard offroad.
ynoteh, as to larger spring perches, they would be acceptable to a point but if you are going to go to a taller perch you would need to go heavier material and a wider weldmount area on the axle to handle the extra shearforce. This has been looked at on many offroad forums for years and most agree that it is really not a good idea as it introduces many other problems, some stated above but also things like axlewrap. These same effects come into play using lift blocks in the rear and is typically why lift blocks are considered a bad idea anywhere on a rig that sees offroad.
