Rear suspension travel with Firestone F9000 bags - The 1947 - Present Chevrolet & GMC Truck Message Board Network

drewskiren · 02-15-2011, 02:36 PM

I read on the Firestone website that these bags are 10.25 inches fully inflated, 8.25 at ride height, 6.25 fully deflated. If I install these almost directly over my axle what kind of suspension travel will I have? 8.25 - 6.25 = 2 inches??? That doesn't seem right. I think I want them at the axle (1 to 1 ratio) so I can haul heavy loads. I am also wanting the smoothest ride possible with an empty load. Help me understand please.

They have much more travel than that I would say 6-8 inches at least. I have mine mounted in a 1:1 set up and they ride awesome. No better bag on the market when used in the rear IMO.

Drew I was just checking out your gallery trying to figure out what you were building. Your shop is awesome! I;ve been in the planning stages for mine, what size is yours, and is the upstairs big enough for a pool table??

My shop is 28 by 36 with an upstairs apartment to house missionary families when they come back to the U.S. The apt. has a full kitch and bath - 800 sq. feet. Across the rear roofline is a nearly full width dormer to give me a lot of 8 foot tall area.

Thanks for the responses, not sure why the Firestone site has those specs.

should be 4.5" closed, 12" open, RH at 9 - 9.5", 1500 lbs cap at 100 psi. This is the bag i'll be using on the back of our JT project.

rob is correct the proper ride height for this bag is 9-9.5 don't worry about pressure be it 15psi or 115psi make sure the bag is at the 9-9.5 installed ride height, weight will determine the actual pressure which will vary underload.
