Air Bumps?

[ILikeMud]

Air Bumpstops, I know what they are, dur bump stops.

However what is the advantage of air bumps over basic rubber bump stops?

[fpkites]

From what I've read, more for baja stuff where you spend a whole lot of time hitting the stops, but you want to soften the ride.

they're basically short air springs that progressively slow the suspension down before bottoming out. they're good for helping soak up BIG bumps when going fast, but are pretty pointless for slow stuff. your yota probably won't be able to go fast enough to move 'em

not true. They are good for leveling yourself out while rock crawling. Think airbags on a lowrider. They can manipulate the suspension and droop independently from one another. A buddy of mine runs them in his buggy and they would be UBER-bling if you wanted to drop the $ to put em in a ZJ.

Puma,

do you still have that link to the movie of the guy installing those?

didn't think of using them like that, but wouldn't you only get like 4 inches of adjustment max. and have to run an air supply to them to use them like that? i guess it would help on off-camber stuff if you rigged them to act like adjustable helper springs and had your suspension set up to ride on/ close to them.

WTF, Air bumps are simply 2-4 inch air shocks. They don't have an in cab adjustment.

If your goal is to run very little uptravel they will come in very handy. They will help with the thud you get from bottoming out, specifically in the low speed but rough situations. Even though you might crawl they will be worth every penny the first time you air out over a hill climb or decide to run dunes or cruise that pot hole filled road to the trail head. Etc. Etc. Etc. BTW, they work great with coils or leaf springs.

my thoughts exactly... maybe you could run an air line to them and keep them at a really low pressure, then when the axle hits them up the pressure via a valve to force the tire down 4 inches at the most?

Or you could just learn to pick a line and drive.

that could be a slightly easier alternative

we must be talking about different things. These are remote-operated adjustable bumpstops. There is an in-cab control for all 4 bumpstops.

Besides are not these charged with nitrogen like air shocks? I don't think running on board air will do a damn thing for adjusting these. Just my $.02.

in the lowrider/ minitruck scene they've used nitrogen-filled airbags/ cylinders to get cars to hop a few feet off the ground (they carry huge tanks for the nitrogen supply)... i'd think something like that would be pretty high-pressure and could be rigged up with the bumpstops instead of bags...maybe then you could just jump over rocks instead of crawling

WOW, this went downhill fast.

Quote from fourwheeler,
"How Jounce Shocks Work
The Jounce Shocks begin working during compression. As a fixed-containment air spring, the Jounce Shock can convert a tremendous amount of mechanical energy into heat. The effect is virtually transparent until the suspension system reaches the 3/4-compression mark. At this point, you would normally raise your shoulders and squint in anticipation of a hard bottoming-out, but instead the Jounce Shock piston compresses a cavity of nitrogen and quickly transforms the would-be violent energy into heat, thus reducing the harshness of the impact. The graph below illustrates these forces with and without the Jounce Shocks installed."

Maybe this will help.

how did this go from air bumps to mini trucks?

anyways to answer your question tony, the main advantage that i see is its softer when your going to bottom out the suspension. i know with my bump stops its kinda like hitting something with a rubber mallet, however with the air bumps it slows it down more progressively. at least thats my understanding.

they are not independently controllable for that stuff you need an actual air suspension, they make them for the tj http://www.offroadonly.com/products/suspension/airock/

sorry for the hijack with the minitruck shit, just trying to figure out how the hell you'd do what puma was talking about and being a jackass. basically they'll make bottoming out less harsh.

Now that's tempting me.
I need to finsh my crap first, can always improve later.
