What is the lowest you would drop without notching the rear frame?? - The 1947 - Present Chevrolet & GMC Truck Message Board Network

I am planning on going 6 inch drop in the rear of my '67 but some people will notch the rear at this height and some won't.. how much suspension travel would I have left before hitting the frame?

I can't measure mine at the moment, since it's all apart.

Thanks!

according to the experts at ECE (early classic enterprises) the lowest static drop without notching is a 4 in the front and 6 in the rear or a 4/6 drop.

4/6 is really common to go with and no cutting

I have a 5" drop in the rear of mine and I have plenty of room for another inch with no clearance issues.

Excellent..! Thanks.

The problem with a 6" drop in the rear is that you'll never be able to haul much weight or you'll be riding on the bumpstops or worse, the frame. I have a 5" drop and have cut the bumpstops so that the axle will hit those just before the frame if it were to ever be loaded that far.

6" on a SWB
5" on a LWB
Then they will both sit about the same height due to the extra weight out on the back end of the LWB.

Im 6 inches, and my axle hits the frame on speed bumps on occasion.

So what about a LWB that's been converted to a SWB?

Seriously though, hmmmmm I'm not sure I agree with your statement however I'm 1500 miles away from my truck and can't argue with no way to back it up.

I just don't think the 12" is going to make a difference.....although women have told me otherwise.

My 69 Tahoe sits way more raked now than it did as a Burb. That's 20" of body and frame gone. Though I'm sure the effect is more pronounced in my situation than on a truck because of the glass and roof.

well i guess I can always notch it later if it becomes a problem.. I wonder if it is possible to do without removing the box..?

72highlander · 05-23-2007, 11:27 AM

i think you could do it without removing the box, but it would be a serious b#$ch! i took my bed off in about 10 minutes and 4 guys and i promise it would save you tons of time in the long run.
