lifting with blocks

[powerstrokin87]

I have a 6 inch lift on my truck. To gain the lift in the rear I went with blocks obviously b/c they were cheaper than leaf packs. the block I got from superlift were not wedge shaped like the factory block and when I called them up they said that flat like I had was better than wedge shaped. I just got one bigger block I believe 5" so I could replace my factory block and not have to stack them. Is this goin to cause me trouble with my drive shaft angles and wear my pinion in the long run?

It won't hurt the pinion, just give you vibration and decreased life of your U joints
The basic theroy is if you have U joints at both ends of the DS you want the angles almost equal..under load, this usually requires 1-2* lower pinion angle at rest.
If you have a CV at the trans you want the pinion pointed at the CV under load..same 2* lower at rest+-.

Now if you have a Carrier bearing it gets lowered when you raise the rear.

It can drive you nuts finding the correct combination..sometimes flat blocks work sometimes angled..when useing carrier bearing shims.

Sometimes nothing seems to work perfect!

Your truck came from the factory with BLOCKS....if FORD thinks they are ok then I would say they are fine....course...I would not run a 12" block...

you'll also find that the larger your blocks get, the more extreme axle wrap you'll get too - which really sucks and is hell on your rear u-joint.

If they are so gay, why don't you change them? It's not like your running around town with a Rainbow sticker on your back window is it.

I had every intention of upgrading to full springs when I had the money.
but I choose to keep food on the table for my 8 month old boy than to buy a $600 dollar set of springs.


but I still dont like blocks.
