Jeep ZJ/ZG Bump Stop Rear Axle 52087993 - Upgraded Version

Since the metal cup where the original Bump Stop gets inserted is no longer available, and my old ones consists out of more rust then steel.
And as I lost one Bump stop because its PU foam turned into a crumbly mass I desided to createy my own Version of this bump stop witch works without these metal cups.

These BumpStops fit for all stock height ZJ/ZG and fits perfectly in the factory metal basket. For litet ones the attachment point on the chassis rail has to be raised.

By using the below print settings and TPU 95A filament you can create a very similar to a new original bump stop. In terms of flexibility and durability.

i tested the stability of the printed TPU part with the entire weight of the vehicle (Picture attached here). The bump stop works great (as the original part), just witout the need of the metal cup. Since my version can be screwed directly to the chassis with the original screws

For all those who want bump stops that do not look like 3D printed parts, I have also created a mold.
With this mold PU-casted Bump stops can be created.

I have used SIMPACT™ 60A/1. Which I have dyed black with SO-STRONG™ Pigments.

I also created an OE-Style Version of the BumpStop. If your metal cups are still in good shape and you would like to keep them:
