SAS Using 70's axel question..
Ok, I did try searching for this but couldn't find quite what I was looking for..
It's said you need a 4"-6" lift in order to do the SFA conversion to make sure the pumpkin clears the crossmember. But, how much compression room does that give you? I mean, if the front end got pushed up suddenly due to offroad conditions, how much space does it have before it slams into the crossmember? And if you're flexing really hard on something, and it's compressing the side that has the pumpkin on it upwards towards, is it going to hit the crossmember from that?
I really want to do the SAS, these were just some concerns I had about it before I started doing it.

what truck is it? you could do the bumpstop as was mentioned but if your gonna be hitting offroad and you will want to get bigger tires esp with a D60 strength...just go ahead and get the 6" lift and not worry about it! i dunno what truck it is your talking about but when i did my SAS on my 85 i had a good bit of room and I know the 70's trucks had more room under the truck in regards to crossmembers hanging down. so i doubt it would be something to really worry about.

I do realize that a bumpstop would keep it from hitting.. but if you have to put a bumpstop that keeps it from flexing much, then the conversion isn't gonna do me a WHOLE lotta good, other than the fact that it's stronger..
It's a 1981 F100, I've currently got more 85/86 bronco parts in it now though, as they use the same frame and everything..
I'd just like to hear from some people that have done the conversion, and see if they've ever had any problems with things like that, and whether they have to use extra long bump stops, or what.
