integral subframeconectors

[r.friborg]

Hi


When I am changing my floorboards I will construct some integral subframeconectors. But the problem is that I don´t want to weld them to the subframe because I want to be able to take the subframe of.
Can I weld some 3 mm plates around the subframe mount and then weld the connector to that ? Or will that result in poor performance from the connectors.

Dse will sell you a set with a crush tube installed instead of welding to the subframe[URL="http://detroitspeed.com/ElmersPage10.html"]Go towards the bottom for info. They're prices are pretty fair $175 normally probably a reasonable charge for the mod.

Why does this link take me to the Microsoft site?

Hi

What is this "crush tube ".
But I am going to fab my own set. Because I live in Sweden so they will be pretty expensive to me. At leats 300$ befor I have them in my hand.
More tips please.

Sorry, I fixed the link. You can't link to anything other than their home page. http://detroitspeed.com/ Go to the projects page and click on Elmer Millikan's Camaro. There is a picture near the bottom of the page. The crush tube is similar to how your steering gear box bolts pass through the sub frame. Basically, you just drill two sets of holes through the sides of your sub frame and weld in a tube similar to a sleeve. Then make some connector brackets. Make holes in them that line up to the holes in the sub frame. Install nuts and bolts through the holes and use tubing and bolts that will fit snugly so there is no slop. If you have any more questions just ask. I usually check the site every night. Hopefully this will give you a basic idea of the process.

You can link to other pages on their site. The problem with that link was the two "http://"s on it.

Here's the fixed link:

I tried that last night after I saw the screwup. No matter what I did it would'nt work maybe it was just a temporary problem.

I just built my own out of 2 X 3 X .125 rect. tubing very much like CarlC has described on his website. I just welded an extention onto my subframe and bolted to the connectors. I welded crush sleves inside the subframe connectors for additional strength.

Thanks for the godd input.

No problem let us know how it turns out. I can call DSE and get the bolt and tube size if you would like.

[r.friborg]

That would be wery nice if you did.

Thanks

I talked to Stacy at DSE she said they use 1/2" bolts. she also said they reccomend that you just plug weld them instead. Plug welds really aren't very hard to remove either. It made me think a little more about how to attach mine.

I did something similar to Davezz28. I created a clevis (attached to my DSE subframe connector) and bolted it through my subframe (a Wayne Due subframe) using crush sleeves in the subframe. Here is how I did it:

1) I installed (temporarily) the subframe and the SFCs and created a template for the 4 clevis pieces (2 each side) out of cardboard

2) I cut the clevises out of 3/8" thick flat stock (probably a little overkill) and drilled the holes for the bolts (on the subframe side of the clevis) and drilled a couple of holes on the SFC side for plug welding. (I think I used 5/8 or 3/4 dia bolts...again a little overkill)

3) I then clamped the clevis pieces in place (between the installed SFC and subframe) and marked their location and the location of the holes in the subframe.

4) I had purchased some pipe that slipped over the bolts that I used (except I had to run a drill through them to clear out some of the welding seam) so I then drilled the holes marked on the subframe to the O.D. of the pipe.

5) I then cut the pipe to length (width of the subframe tube) and welded along the periphery (on the outside). These are my crush tubes.

6) I then bolted the clevises onto the subframe and welded them to the SFC (using the plug weld holes). I then removed the SFCs (with the clevises welded on them ) and completed the welding.

I've attached a few pics. The pics also show a cross-brace for my truck arm suspension between the SFCs so that may explain some of the structure that may not be familiar. Hope this helps and good luck.

One thing to think about is to make sure your subframe is centered and your sheetmetal all bolts up before you weld up to the subframe. A buddys frontend would not line up for anything until he remembered to x the subframe up.Just my 02 cents
