Well I've gotten nowhere on this after searching:
I bought used inverted sport shocks. They are the pfadt 16 way ajd. (not coil overs). The guy removed the bump stops below the shock body and sent delrin replacements. Art least I think that in the case. I have four sets of bushings or bump stops. I tried to undo thebolt to put on the stops but can't. I have no idea if out needs the stops out if that is what they are, I assume it does because one front had a tore up one on the front. Pics coming.

I have these with the original soft rubber bump stops.

They do get chewed up.

I think you need something so that the shock does not get damaged on a hard bottom (pothole scenario).

I could be wrong, but I don't think delrin makes a good bump stop. Rubber or poly is better, you WANT some give to the stop.

I never tried to get the nut off, maybe call Pfadt monday.

Yeah, I just wanted to accomplish it today...here are pics.

If I see the picture correctly, that just happened to mine. Sent them to Pfadt to have new bump stops put on as you have to have the right machine to install. $50 per shock plus shipping to and from. Pfadt says it happens when car is lowered, which mine wasn't, or when sway is too soft when running grippier tires. Good luck with it.

I threw out my bump stops. If you want bump stops, think of them as a tuning tool. Different stiffnesses to get the results you want.

Thanks for the replies. The money I saved on buying used will, almost exactly, be eaten up by $50 a shock. Such is life of the over eager online buyer I guess. So Mountainbiker2 did you run with no bumpstops?
Will try to call Pfadt tomorrow.

Bump stops are pretty generic, I would not pay to have them installed by a race shop.

Get 4 from a circle track supply company that have the correct ID.

Make a cut thru 1/2 the diameter so you can slip them on.

They will probably stay on by themselves, or you can cut a groove around the OD and use a zip tie to hold them on, maybe a metal zip tie like used for header wrap.

Shouldn't run more than $20.

Thanks guys, spoke with pfadt today . Great company, I'm sending them photos and we'll go from there.

Hey guys. We wouldn't recommend running without the bumpstops, not because the shock is in a whole lot of danger of damage when bottomed out, but more because of the sudden change in handling that's accompanied with the shock completely bottoming out.

The lower mount isn't particularly difficult to get off, but since it's secured with loctite on the threaded shock shaft it can be a little tricky to remove without a way to keep the shock shaft it's self from turning. We've got all the equipment here and available, and if your shop can secure the shaft without scoring the shaft it's self we can walk them through the disassembly process. Bump stops are cheap, but chewing up the shaft with a set of vice grips is a great way to destroy the shock. More often than not we can turn a set of shocks sent in for a bumpstop replacement over and shipped back out the same day.

Shocks on the way to Pfadt! Thanks!
