Perry Parts 3D Printed Bump Stops

In my hunt for bump stop ideas for my basic trail suspension, I came across these 3D printed ones from Perry Parts. The concept seems novel with the designed air passages to create different low speed and high speed rates, and if I’m understanding them not putting as much force back into the rebound for the shock to handle as a typical rubber bump would.


Anyone have any experience with these? Gimmick? Stick to Eibach bumps or basic rubber?
With what I am figuring will be low up travel numbers I am trying to avoid just hard rubber and barely better experience than metal on metal on full compression, these seemed promising.

huh I'd like to try them out, interesting! I like foam bumps for this same reason.

3D printed bumps have become pretty common in the Toyota world the past few years. These actually look identical to what I just took off of a long travel Tundra as we redo the front suspension with hydros. People usually rave about the 3D printed stuff though i don't have first hand experience riding with them.

Sure enough they make a bolt in application for me, but I did email to see if I can get some specs like “usable stroke” or whatever you’d call it for rubber style so I can mount it where I want. No response yet, so when I’m closer to ready I’ll call to see if they can give more data.

These could work…

If you can find some files I’ll print them and ship to you. No charge. Except at the moment the only TPU I have is pink.



I just got a Bambu P1S, and put a chamber heater in it. So far it has printed Nylon, ASA, and ABS like it was all PLA (ie super easy.) Haven’t had anything to print in TPU yet, but, I have some. I have some black somewhere from when I was printing rifle stock pads, I’ll have to find it.
