I Beam bending

I'm planning on bending a spare set of i-beams for a 66 F100 2wd. Anybody know the max drop length or other specs I should know? How much would it cost to bend them? I'm planning on keeping my build low buck and old school-ish so dream beams and a CV swap are out. What other parts would I need to finish the swap?

I was thinking about this for my truck, but 2 inches is pretty much the max.

Sometimes they will "at some point" break as you bend them past 2". Although 1 guy I read about got away with 3" don't know how.

If I were to do it I would of needed new shocks to go along with it so it ended my low-buck idea.

I heard, but never seen a truck lowered 2" with coils, and 1 inch with re drilling the I beam mounting hole up 1 inch.

The rear you still may need new shocks, and the angle of the shocks maybe to extreme to work properly.

Keep in mind the bending will be done once the beams are in the truck. You'll need to set it up on an aligner after you get your ride height where you want it. Both beams could require a different amount of bending depending where your camber is. The max camber I've gone is about 3 degrees and didn't have any issues. A buddy of mine went 4 degrees on a '72 and one of the beams snapped. Find an old school alignment shop that knows the procedure.

Like the guy above said Old School Shop is one way to find people still up on bending beams.

But heavy truck repair places with alignment racks still align trucks this way. Call ahead some don't work on small trucks. Remeber nearly all box trucks have straight axles.

Thanks for the info guys. I'm not looking for an extreme drop just something to give it a decent rake.

I did a 3/5 drop on my truck for a grand total of 50 bucks. Up front I cut 2 coils and had the beams bent at a quality alignment shop that did it on a frame machine but it was an afterhours family deal so no cost estimate there. The rear I flipped the hangers and installed new u bolts and shocks which took up the $50 I spent. I have put 3000 miles on the beams since bending with no issues but they were not heated at all it was all done with the proper equipment. I would really like to go lower but it gets it down well enough for now and for the price no complaints. If you do the hangers in the rear 77 chevy 1/2 ton front shocks fit perfectly in the stock mounting location.
