Double Hump Crossmember
Been thinking about edoing the exhaust on my truck soon, and while I'm at it I figured I could replace the trans xmember with a double hump version. What are the cons when using a double hump xmember with a lowered truck with headers? The only xmember I could find on ebay was this one, says for a 4x4, this will still fit my truck right? Thanks, DOOCE

Re: Double Hump Crossmember
yes that is for a 4x4 it is made for a 203 or 205 t case. it will hang down a few inches from your frame but i dont think that far.

Re: Double Hump Crossmember
I don't think that one will work for you. Here is a pic of mine.

Re: Double Hump Crossmember
Is that the same xmember I posted? I dont know why your headers hang down that low, mine are nice and tight to the cab and should clear that xmember setup just fine

Re: Double Hump Crossmember
My headers are Hedman Elite long tubes for a '73-'87 big block 2WD truck. The picture above is a little deceiving because of the camera angle. The collectors line up exactly with the large 'humps' in the crossmember. I have about 1/2" clearance from the top of the exhaust pipe to the crossmember. But that also means the bottom of the exhaust pipe is about 2-1/2" or so below the frame rail.

Re: Double Hump Crossmember
that one you have posted is for mounting a transfer case, not the trans.

Re: Double Hump Crossmember
The 4wd cross member is not going to work in a 2wd. The transfer case mount hangs down about 6"-8" below the mounting pad on the transmission case. You would need to have a large spacer for it to work.

Re: Double Hump Crossmember
I have Hedman long tubes and a double hump crossmember. It looks like Hedman made these specifically for this crossmember. It fits well and looks great, but I run stock ride height and intend to keep it that way. For the stock height, it's perfect. For a lowered truck, long tubes are going to hang too low no matter what you do.
As mentioned above, I would look into 3/4 length Chevelle headers and a custom made crossmember. That is the only way you will get the exhaust tucked up into the frame.

Re: Double Hump Crossmember
If you already have the headers, just build one to work. It doesn't take much, and you will know that it fits.
