Bags & bumpstops...

I've decided to go with bags all the way around on my '66, and I'm converting to a '72 front suspension at the same time. Question is, before I take the lower A-arms to the powdercoater, should I do anything about the factory metal bumpstop brackets? Cut em off & shorten em? leave em off? leave em stock?

Drill out the spot welds, knock 'em off with a hammer, and grind everything smooth.

See pics at bottom of THIS THREAD.

That thread needs to be a sticky!!!! MrShelley that is one of the best threads I've seen on this forum the 5 years I've been here...explains everything...if they can't understand it they shouldn't do bags. Where did you get the bumpers for the front from?

http://www.slamspecialties.com/ bags have internal bump stops so no need for lower stops.

I got those bumpstops (in the FAQ) from Jegs for like 8 bucks.

In those pics, the front bags looked deflated. Is this a correct assessment? If so, how the heck does a bumpstop thats that short work? What is the minimum height requirement for those bags?

Building a small, high rpm engine with the perfect bore, stroke and rod ratio is very impressive.
It's like a highly skilled Morrocan sword fighter with a Damascus Steel Scimitar.....

Cubic inches is like Indiana Jones with a cheap pistol.

The bags in those pictures aren't connected to any airlines or under load yet. It was just to illustrate the assembly portion of an air bag installation. So they do compress a bit shorter. But I know what you mean about the bump stops not even "bumping" or "stopping" anything.

In actuality, I will probably trim the bottom of the lower "cups" to further lower the truck and allow the stops to be functional. The minimum compressed height for those bags is 2.9", so as it sits now, the suspension tries to crush the bags smaller than that when completely lowered (ie. the bag acts as a stop).

If trimming the cups to a shorter height doesn't remedy the situation, I'll just get taller bump stops.

Savvy?

Yep, that makes sense. The ones I've seen built were all taller so that's why I questioned (most all of them were the same height of stock stands + shorter rubber).

On my trucks, I need the factory bumpstop stands..... w/o them, my tires will buzz the tops of the fenderwells baaaaaaaaad. I have mine set-up so that the bump-stop prevents the tires from buzzing my stock height fenderwells. If someone had raised fenderwells, I could see the shorter bumpstops working.

Your stuff looks good MrShelly. Inspiring too.
