Coil spring front suspension for my 79 GMC

Personally I wouldnt trust it. I would also be concerned about whacking that lower link on something. Thats just me though I like to play in the rocks.
What would you change? I was considering building a custom crossmember that ties all the links together and wraps around the frame.
 
I wouldn't have mounted lower link to the stock crossmember, I think you will bend it. That one link sees more force than any of the others, its one of the disadvantages of a 3 link.

Also, I would use 6 bolts to secure the two "upper" link mounts (instead of the 3 you're using now). I would add 3 more bolts above the 3 that are there. And you don't need to drill big holes in the square tube to get to the bolts, just install the center one first.

Out of curiosity, have you seen the 3 link calculator (first link on this page)?

I plan on gusseting the outer mounts and drilling a few more holes, three bolts arent enough although the outer links are tied to the trans crossmember. I welded plates to the outer mounts and the crossmember to give them and the trans crossmember more strength. The cross member has the stock bolts from the bottom and the outer link bolts that come in from the side attaching it to the frame now.

Its just that the link mount is pretty far inward from either frame mount and given that its a 3 link (that center link has to resist all of the twist from the axle, as opposed to the "uppers" which spread the load 50/50) I would think there's a good chance it will bend up that crossmember.

Would you recommend boxing the crossmember?
 
Do you guys think the stock crossmember will be strong enough? I dont hardcore wheel this thing but I do want it to last.

Some triangulation might be good to do, from the link mount towards rear tire.

Where those coils are from? Ford?
 
Trans crossmember reinforcment.

I had some time after work so I started boxing the trans crossmember.

how much did the upper coil mounts from Ballistic Fabrication cost? Do you have a link to their site? I want to do a SFA on a 96 yukon, and i think that coils might be the way to go. Thanks !

The upper mounts from Ballstic were only $65. They come unwelded and you need to true the 1/2 holes they punched in them but they are real nice pieces. Heres their site http://www.ballisticfabrication.com/
 
Track bar mount mod

I modified the track bar mount. I added an outrigger towards the rear, boxed the mount and added a brace that ties it to the engine crossmember and boxed the frame above the mount. Also I added a 1.5x1.5 .25 wall box tube brace that attaches to the opposite framerail.

Its pretty much finished

I adjusted all the links and the coil mounts unfortunately I ordered the wrong length drag link from Sky (too short) so it will have to wait until monday for a road test.

I wouldn't feel too safe with the panhard rod bracket at the frame side considering the length of it hanging down.
I'd look into swapping the engine crossmember out for one that dcubb fabricates. It incorporates a bracket to mount a panhard bar to it. Its very beefy and solid, with excellent welds. You can search his name to find info on his 'member.
 
Thats awesome!

That thing is sweet! I want one. Thats what I pictured in my head. Whats the link to his web site? I didnt see it.
 
He doesn't have a site. Just send him a PM and he'll get you set up. Meanwhile, here are some pics for admiration:

Steve from M O O used a front suspension like this. Have any of you guys seen it in action? Im looking for feedback before I test it out. The guys on Pirate are pretty conviced this design (inverted three link) isnt wise.
I saw pictures of Steve Frisbee in action and would like some advice from him.
Does anyone know how to get in touch with him?
