OK, I am looking to lift a my 68 longbed on a 78 chassis. I think a few inches or so would give me the room I want for the 34-10.50-15 tsl's I've got. Is it a horrible I dea to modify the spring buckets & drop them about 3" and then do a shackle flip in the rear? I've got a couple buddies who have done this to there mud trucks, but I don't know if it is such a good idea.
The only reason I considered going this route is because I have access to the parts off a wrecked truck to modify. I feel fairly competent when it comes to fabwork. On this truck I cut 2" out of the frame, boxed it and fit it back together. I built the 429 myself as well.
If i were to buy springs & shocks for the front, how about the shackle flip in the rear, is this an acceptable practice?
I have the [broken record] SKY Manufacturing shackle flip on the rear of my bronco for about 4inches and like it. You might have problems if you tow/haul a lot of weight because the shackle will be in compression, but you can always upgrade to a beefier F450 shackle and bolt [/broken record].
All that said, are you sure you need to lift it? 34's will fit fine without lift. I ran 36s without lift on my '78. Unless the 68 body is significantly different. If you just want to lift it, go for it. I went with superflex 4" coils, drop brackets, brake lines, shocks, drop pitman and drop trac bar bracket all from bronco graveyard.
Either shackle flip or do the sky bracket in the rear.
Very good way to lift the rear, but it drops your hauling ability a little.
For the front... cage or deaver(superflex) coils would be the best way to go. Stock springs have more than likely sagged by now, and new springs wouldn't hurt, but other than that... droping the coil buckets isn't bad.
You can get most things off of JBG for right around the prices Kris listed, probably a little cheaper.
You'll want a drop trac bar mount as well.
You could always cut the corners of the fenders for the little extra clearenss you'd need...
HERE is a link to a picture of my truck to show tire clearance. I jacked up on front tire and it did not hit but it comes within 1.5" of the fender. It sits a little nose down as well, I wouold like to cure this when I lift it. What would you guys do if you were me?
They have coil springs that give 1.5-2" of lift.... might look into something like that.
IF it were me, and I'd (think it was just too low), I'd get the 1.5-2" coils, 2 or 4 degree C bushings (probably calls for 2), get some grade 8 bolts and do a shackle flip and pull the rear block.
I'm guessing the block is 2" (if it has one... it's a 1/2 ton, so if it does it should be 2") The shackle flip would give right around 3" of lift, so you'd end up with 1" lift in the rear.
And 1.5-2" up front. You wouldn't need to worry about drop brackets, extended brake lines, or anything.
I looked into all this kind of stuff when I converted my truck (to 4wd) and then decided that new front springs were a good thing since the stock ones were 30 years old. I used rancho 3" coils, but it was really more like 3.75" lift since the stock ones were sagged. On the rear, I added leaves and did drop brackets, but the shackle flip would have been MUCH easier. Here's 2 pics with the 3"coils and 33s and 36s
Hopefully, this helps guage how much clearance the 34s will have. I say buy new fronts and shackle flip the rear.
Theres a link in my sig to a thread where I lowered mine 2.5 inches on my bronco. But this was just for on the cheap, and if I had had any sort of a budget I would have just bought coils.
I have looked at doing that for another 1.5" lift, but the cage coils are pretty cheap, so I think that will be the way I go if I do lift it some more.
chrono4, how has that home lift been working for you? I have been thinking of doing the same thing to mine. Did you have to buy anything else like a pitman arm or track bar mount after the drop?
I didn't buy anything. I only lowered them 2.5 inches, so you don't need any of that. I just blasted the rivets with the torch, cleaned the area all up, and burnt it in.
