Mounting air bumps up front

[HeavyMetal]

I did a bunch of searching tonight, didnt come up with what I was looking for so I figured I would post up, if this has been covered in the past, my apologies but it is beyond my "search-fu"

I just bought some FOX 2.0 resi shocks...and my next step is now the air bumps. Im looking at getting 2.0 diameter 2" stroke SAW airbumps soon, and I am trying to find the most logical least involved way of getting them mounted in front, inside the coil.

I am not terribly familiar with air bump cans/mounts in an XJ, could someone possibly post up their experience with this? I suppose I will cut off the stock bump/coil tower, and replace it with the air bump in a can/tube of sorts, but thats where my thought process ends.

Also I am looking to have them strike an RE poly bumpstop in the coil bucket, or perhaps a UHMW cylinder..good idea? i dont want metal contact, as I have heard that noise gets pretty annoying while trail riding/getting to the trail.
thanks guys.

Inside the coil can be quite a challenge to keep the springs from hitting/rubbing the sides of the bumps. If thats 100% sure the way you want to go, T&J sells a weld-in kit that mounts them there. I'm sure Tom will chime in.

to be honest, I am not sure how else I'd mount em in the XJ up front :dunno:

x2, it is a little tricky, although if you are going with a 2"stroke air bump, you are better off. When running a 4" stroke, if you aare flexing the suspension alot, it can come in pretty close contact with the coil. Stick to the 2", and put it inside the coil and you will be happy!

I miss curt. He was the one guy I saw more in the desert than anywhere else!

Curt, you gotta plan coming out for a race. Maybe the oraf 500

You using those bumps for jumping corn fields? haha

Tony, post pics of how your XJ's bumps were installed.

Awesome thank you for this! Now I assume this tube/can goes up through the fender well and welds on the top in the engine bay, and below in the fender well? in sandwich form?

Yup, thats exactly how they mount. I did mine a little differently, they were mounted outside fo the coil.... you can see the mounts in this picture, but it was alot more fab work, and test fitting to get the strike pads to align. I think your best bet is to go down the T and J path, and use a 2" stroke air bump.... you will be in greatshape with that!

This was my setup

+1 for 2" stroke bumps.

thats because you take the best pics....

2" inch stroke for sure. otherwise you will be hearing the bumps all day.

does that tube have a ring in it towards the top where the can presses against? i assume the set screws just keep it from falling out onto the ground

2" airbump, in the coil, with a UHMW pad.

This is why people are worried about it gettin' into the springs:

It worked for a while though. Every single person who ever rode in that thing with me - including Dan at the last RCRocs race - was amazed at how well it went over the rough stuff at speed.

The eventual demise was due to the unibody inner fender tweaking to the point where the passenger air bump was pretty much leaning against the spring.

So run 3" bumps? Like a 4 inch with a 1" spacer? I think I made one of those one time.

is that what you run, Crazy?


JK.

lol

Nice vid btw. Someone I know bought an xj because of your vid. lol pretty cool huh?
