Ok, so I guess my words on the bump needing to hit the pad at or near perpindicular (sp*) (90*) were ignored.
As the bump makes contact with the pad, and is then compressed the snub or (point-of-contact) will have to slide toward the wheel or outward in your application on the pad.
1. that will be very hard to do and not tear anything up on top of wearing the snubber down fairly fast.
2. While that is happening the pressure from the compression of the bump will have leverage on the airshock. In the top picture it will try to rotate it clockwise and up. Therein binding the heim in the airshock.
To try it out: suck the winch down, or figure out a way to suck the front down and do it slow and watch how the airbump compresses and pushes out.
I like the idea, and it will work kind of...... But I think anything hard and the airbump mount rotates up and out, wiping out the airshock heim, and bending/tweaking the whole airshock.
Also the advice that the airbump can not push higher.....the airbump will only push as high into its can as it has limitations. We all agree here. Usually the screwed on nut that the ram extends out of that would be the "Interferance". That will not change. I see the whole bump/can/mount assembly pushing up the body of the airshock as there is nothing "Interferance" above the can mount to stop the assembly from creaping up the shock body. Clamping force aint **** on a suspension. One hard hit and that thing slides right up.
I was a believer then thought about it at lunch studying that photo. I like the out of the box thought, but there are a ton of forces in there you are not accounting for.
Whatever you do, please take pics, and report back.
