I wonder any you guys out there have done anything with your I beam suspension? I think my front rake is due to sagging springs because when I jacked the front to replace a tire I noticed it sat higher for a couple hours before going down to its usual height.

 

I have a 79 but I have never done anything to the beams. Since our trucks are in the 70's I would suspect the springs will be weaker due to just the age of our trucks.

 

You can't do anything with the beams themselves. You can change bushings , springs, king pins, shocks. The beams themselves can't be bent or heated. Same for radius rods.

I do know where there is a junkyard that has about 5 acres of Ford trucks. See my post on" I found a honey hole" Just checked Oriley's had everything except the beams and radius rods.

 

Can I put on heavier duty coli springs?

 

I would think that just replacing with a stock spring would raise it back up and be what you are looking for.

 

Yes you could out of a 250 or 350. But I have agree with Chief. What engine are you going to put in it? If you go with a big block , when you get your springs get the ones for a truck with that engine. A heavy duty spring will give you a harsher ride.

 

I will put in a hotter blueprint 306 crate engine. 3600 for 390HP sounds like the way I want to go. I just want to raise the front end a little if I could without lifting. Do the coil springs need any type of insulators top or bottom for dampening purposes etc. ?

 

I am with Chief the new springs maybe the answer.

Get in touch with these guys. They are old school use to do custom work. At one time they were the go to for springs

I would think that new springs would raise it back up and be enough for the engine upgrade, I personally dont think there would be that big different in engine weights.

Bronco graveyard as they have stock height up to 6 inch lift: $90 to $189 depending on how much lift you want. Coil Springs-Broncograveyard.com

Lower spring pad is $30 bucks each: 1976-1977 Coil Spring Lower Pad-Broncograveyard.com

I do not seen any upper spring pads, never had mine apart so I can't tell you if they have a lower.

 

Thanks, I am excited that leveling out the truck maybe no more then just new coil springs. The truck is 2wd so I don't really think I want to lift it. 3 inches maybe if I ran out of other stuff to do.
