Im assuming the rest of them are like that.

Is there a good after market replacement compared to oem?

What does a bad bump stop cause?

I think OEM is just fine, it prevents the shock from travelling too far preventing a wheel from going into your fender or damage to the shock?

About $5-8 dollars at the dealer. You should also replace the $3 plastic tube that goes around the bump stop. These parts are also available from OEM suppliers, such as our various forum sponsors.

They are there to act as a highly progressive "spring" as the shock nears the end of its bump travel. Hence the name "bump stop". One that is rotted out like yours is no cause for great concern unless you're planning on rallying your car.

You simply unbolt your RSMs drop it down remove the bump stop put new one on and with new cover if you get one bolt back up good to go!

A guy I know would say that your springs are too soft for your driving and you're hitting the bumpstops too often ;) :) :devillook

Very simple DIY fix for sure. I got heavy duty ones when I installed my GC coilover kit, but for your application, the oem ones should work ok. Drop the RSM, compress the shock, remove the old bump stop, install the new one, and reinstall the RSM. If you're on a relatively smooth autox surface/parking lot, I wouldn't worry too much about replacing it ASAP, just get to it eventually, because depending on the shock you have, you could blow it out on a pothole or something. Some shock brands have built in bumpstops, others rely on external stops.
