I've been searching this forum and other f150/4x4 forums for a couple of weeks now. And thought rather then keep reading these threads from ~06 i'd see if i can get a quicker answer by just asking the questions.
I read that an easy way to do the shackle flip is to take the rear shackles front mount and put one on the back as well. (both front and back mounts would be the same then). I know that it would also adjust the angle of the drive line, i will be correcting that by shimming the axle mount on the shackle.
I guess one of my questions is, do i try and keep the bracket in the same spot (the bolt on the rear of the shackle, inline vertically. Or, with the hinging affect taking place would i then have to move the rear mount forward?)
I also realize that it will move my tires forward, some say 1.5" most say far less then that. Im not concerned with that because im converting my lwb to a swb anyways.
I was wondering if anyone had an idea of how much lift i will obtain by just doing this to the rear (leaving factory blocks in). I will eventually get better shackles for the rear and remove the blocks at that time.
I've read where most of the time its right around the 3" mark because alot of people will do the flip and then remove the block and still be at factory height but it rides better. any truth in that?
This is all going onto a 1979 f150 custom, 400m (fully built) with a 4sp manual trans. Front is still the hp dana 44, soon to be replaced with a d60. The rear is stock for now as well. I've read that on stock front and rears not to go much over 35 unless i want to break stuff.
Im going to end up with a geared/locked d60 up front and still deciding on the rear. I've read that the 10.25" is a good choice for the rear. Its being built for more or less a trail/mud truck. To take my boys fishing out in the country like my dad with me in that truck.

You can it this way but you have to make mods to the rear bumper mount to make it work, spend a little more $$$ and get either the Sky kit or the RuffStuff kit.
You will NEED to remove the factory shim(block) when you do the shackle flip. With the shim in place your pinion will be too high which will cause binding issues.

You will want to mount what ever hanger you use in the same place as the rear is now.

My axle move 1.5" forward when I did my flip. There are a couple of wasy to remedy this, the easiest is zero rate leaf spring, another option is to move the front hanger back 1.5".

You will net 3.5-4" of lift WITHOUT the factory shim (block).

You will NEED to remove the factory shim(block) when you do the shackle flip. One of the best reasons to do the flip is that you no longer need the factory shim to achieve proper pinion angle. With the shim in place your pinion will be too high which will cause binding issues.

Awesome. thanks for the replies! So by flipping AND removing the block i'd still be ~3.5-4" taller then stock?
Maybe i just need to build my current axles up then, because my 2nd time out in this truck i snapped both rear axle shafts, so i swapped another axle under it (had a complete extra running set for my truck...including front and rear axles). Then my 3rd time out i shattered the front differential. After that i parked it and it sat for almost 2 years.
I decided that its time to get it running so i can park the mustangs this winter.
Im planning on running custom front and rear bumpers anyways, so the bracket being in the way will be no issue for me.
I saw your pictures in the newbie thread, awesome looking bronco man!
heck ya man, Im just going to slap some 35" tires (unless i find a good deal on some 37-38" tires) on my stockers. Then when they break again, i'll upgrade at that point. This truck will only get driven when i feel like offroading (with my work schedual that will be like once a month at most).
For now im just going to shackle flip the rear and put some skyjacker softride 6" lift coils under the front. Im really thinking about making some custom shock mounts for the front to run dual shocks. Then this spring i'll add the rear shackles under the rear to lift the ass a little more and get a better ride out of it.

I'd been reading that ruffstuff on these old trucks make them ride RUFF. I'd seen several complaints about the truck being too rough, Now of course there are always going to be certain complaints about a company, you cant keep everyone happy. But i havent heard too much "good" about ruff stuff. Then again i've been a mustang finatic since i was old enough to drive, never really done the whole off road scene til here lately.
Yep, your absolutely right. I was thinking wrong. I'll take a look at their website here.
Good news is... after sitting for almost 2 years, i put a new set of spark plugs in it, some new fuel, new filters, and she fired right up for me. AMAZING!
