Rear bump stop cup removal question for 2/4 drop

[Rock Crawler]

I’ve ordered and received the BellTech progressive bump stops to replace the factory ones. The factory bump stops were hitting the rear axle quite a bit, so I cut them in half which help a lot. But, because there is not as much bump stop left, the bump stop cups are occasionally coming in contact with the rear axle. I want to remove the cups, but I don’t know if I need to remove just the cup part and mount the new bump stops to the plate, or if I need to cut off the entire assembly and drill and tap the frame for the bolt on the bump stop.

I do not have direct knowledge on how to do what you are asking, but this is from BT's rear Pro Coil Rear set instructions. Hopefully this may help you.

Thanks. That’s actually the way I ended up doing it anyway.

So, I decided to just cut the cups off instead of the entire assembly.

Cups on:




Cups cut off, grind, sand, prep for paint:



Paint:



The bump stops came with nylon lock nuts but I decided to use rivnuts instead. The hole in the plate on the truck is the perfect size for the 3/8-16 rivnut I wanted to use, so I didn’t have to modify it at all (win). My rivnut tool wouldn’t really fit in the tight spots so I made my own tool with a bolt, spacer and a couple washers.

Rivnuts installed:

Done:

I used some blue thread locker on the threads to keep the bump stops from backing out.

Job made so much easier this way. I’m old and this thing is a back and joint saver. She even looks good up in the air.
