Are you short on memory? You asked this last night in another thread. https://www.ford-trucks.com/forums/8...es-lift-2.html

I also answered you in that thread.

If all you're looking for is 2" an add-a-leaf should do the trick in the front and you can use blocks in the rear. With that little of a lift you shouldn't have any other issues.
Why did you start another thread for this? If you didn't like my answer you could have asked more questions there...

lift blocks are fine for the rear, but very dangerous for the front!!! save yourself & someone else's life & buy a quality susp. you should be able to do 6'' lift without driveline mods.

You could do 6" without driveline mods barely (I wouldn't recommend it, but I've seen it done, however if you flex at all your slip joint will fall apart), but you'll have to do something about the steering and brake lines by that point. At 4" you should correct the steering and lines. 2" is ok in that you can leave everything else alone.

Wanna know the solution for this? Take a look at the slip joint on the rear driveshaft and check out the length. It is longer than the front. Stop by the salvage yard or driveshaft shop and get the longer one to install on the front and the slip problems are over when slightly bigger lifts are involved.
Small useless tid bit i know.

I remember you mentioning this once before in a thread about the SD leafs. Great little piece of knowledge, and definitely not useless.

So how bad are lift blocks on coil springs? I bough my 78 F150 with 2" blocks already on it. I plan on removing them and doing the superlift front leveling springs instead. So just curious as to how much I shouldn't be driving my truck around. Also as a side question, I was wondering if the back has lift blocks. I am assuming it does but I'm not sure what the stock perches look like. Any advice on this?

Thanks Guys,
Josh

Well in answer to your question I wouldnt drive it around the block as long as the front has it's blocks in it the rear is not so much a problem the superlift is a much better idea kudos

Coil spring blocks are fine since coil springs do absolutely nothing to locate the front axle, they just keep the truck in the air.

On coil springs lift blocks (spacers) would be more acceptable if no bigger than 2" though personally i'd advise against using them and recommend you just install a taller spring but on leaf springs lift blocks of any size are just down right dangerous not to mention illegal, at the very least they'll cause axle wrap and in the worst case scenario can be ejected from between the leaf pack and axle during hard braking or cornering leaving you without control of the truck, front lift blocks are best left for mall crawlers and trailer queens.
