double hump crossmember

[outsider_27]

Is the iceman crosemember legit? Doesn't look that good.. looks to thin and how much is it? Doesn't show prices..

I agree, it looks like it would weaken the frame with the small tube and only bolting to one bolt hole on each side. It also looks like it could tip forward or backward in extreme situations, whatever they may be.

It looks like the one that G-body parts sells is made by Iceman. It may look thin or flimsy, but it's made out of chrome moly tubing. Guys on Maliburacing use these on high horsepower race cars.
Rick (Iceman) makes good products. I have one of his original "heavier" designed ones. His work is top notch.

Yep...Jegs has some fair priced. But if yours is a Supreme they might not fit, even after tweaking. Summit has the only bolt in double hump crossmembers I've found for a Supreme, but they're just shy of $300. I went to a local exhaust shop with a good reputation and they fabricated a second hump on my original for $88 after tax. If you go the shop route, ask questions and make sure they do it right...notch it out and weld in a solid steel half circle of pipe. The shop I went to uses 6" diameter 1/2" thick. Either mark the crossmember where the notch needs to be, remove it, and take it to the shop or you can just drive over with open headers and pray that you don't get pulled over (I did the latter). Unless you or a buddy is decent welder, then you can just do it yourself.

You COULD have a y-pipe fabricated to use the single hump, but I found this to be more expensive than getting the second notch.

I have a Supreme and the JEGS crossmember bolted in just fine. The frames on the Supreme aren't any different than the frames on the rest of the G bodies, except the wagons and ElCaminos.

I know the frames aren't any different. It says right on their website, "Does not fit ANY Cutlass Supreme models or El Camino." So I called for more info and was told by a Jeg's tech rep that the bolt holes on SOME Supremes are located slightly different than a non-Supreme, and they say it won't fit ANY on the site to cover their *ss. The rep claimed to know someone who wasn't able to use a Jegster on his Supreme. I don't personally know anyone with a non-Supreme to let me compare crossmembers so I just took my car to a shop. Also, for some reason I recall the Summit brand being more expensive when I was looking for a crossmember, which is why I didn't get it...oh well

The tech is full of sh*t! The frames are all the same, so the holes are all in the same place. The only thing is using the 2004R crossmember on earlier cars that didn't have that transmission as an option. Even then you can buy the frame extension and bolt it right in. In some cases the body mount bushings are bad and sag the car to the point the crossmember won't go up far enough on the driver's side. Then either use a BFH and manuver some metal, or replace the bushings.
