Air bumped buggy owners, question for ya! (27th Dec 09 at 4:25am UTC)
How do you like them, what brand do you have, how much were they, how easy are they to adjust. How do you think they would work on a full bodied rig set on the bump plates at the fully extended position at ride hight? <-- Does that make sence? At ride hight the bump would be fully extended but touching the bump plate, essentially limiting my uptravel to the travel length of the air bump. Would be a horrible ride set up like this? This rig will rarely see the rocks if ever, mainly a snow killer.

If you set it up the way you were talking about you might as well just get an air shock. That is essentially what an air bump is. They are not really designed to be used the way you are talking about.

I thought an air bump was a bump stop that had a air cushion "charge" that made it more of a gentle stop instead of a slam. Am I wrong?

air bumps are nitrogen and oil, valved for slower compression and rebound doesn't matter so much. It's a little air shock, like travis said. It's quite a bit tougher (in the right application) than simply using your air shock as the limiting factor Riding right off the bump plate is how lots of them work in the crawl only arena, but it's not right. If you have tons of up travel then the bump makes sense to pick up the slack on no more than the last 4" of travel. If you're dead set on the bling factor then I'd suggest limiting the bumps out to 1-2" of travel and running them verrrrrrryyyyy stiff (ie: more nitrogen).... it'll be a harsh bottom but it will still take the load off the rest of the components and transfer it to the frame and axle. In the application you're talking about I'd suggest doing something more like the 4" urethane block bumps. They're silent, progressive, and much cheaper (since you'll be replacing them on occasion in this application) still $80 for a pair. A fox 2.0 air bump is going to be in the $190 range for a bump and can. I can get then if you're still sold!

I run FOA 2.5". They are a 2" bump. I have them set at 115PSI and I think I may need to bump it up to 200. I run them on the front of my rig. The front suspension has a total of 4: of compression. I have 2" of suspension compression before the bump comes into play. I am very happy with this set up. I was debating about getting the 4" bumps but then I would of been riding on them all the time. Im glad I went this route.

I have the fox air bumps on the commando. I run 200psi. They work great and prevent the coilovers from bottoming out too hard. They even held up when I endoed my rig!
