Just recieved my genuine GM bump stops. They are different colors! Part numbers on the bag match. Same size. Both have the BASF logo on them. No dirt, scuffs, etc. Bag appears to be sealed. I don't care if I have color matching bump stops, just wondering if its ok to proceed with install.

Different production runs? One is aged on the shelf, and the other is new? If they are the same as far as compressibility then I'd call it good. If they are different then it's time for a do over.

I can't tell. Pushing on them seems the same. Both hard.

Because it doesn't look like something as simple as red vs black rubber. Almost looks like exposure, or a different type of rubber. Was wondering if anyone else has seen this replacing the bump stops.

Sun exposure? One was at the front of the shelf where the sun could hit it. The other was behind. Would that affect the material?


Cannot see signatures any longer so it doesn’t matter.

I doubt they are super careful about the amount of dye mixed into each batch of whatever polymer they're using. I wouldn't give it a second thought.

Yeah, I hope its just the dye. Agree, wouldn't give it a second though except for the truck sits on them full time in the front.

The darker of the two has had some UV exposure. Nothing to worry about, proceed with installation.

I've seen GM bump stops in both colors. Different dye on a different day for a part where color doesn't matter anyways.

Just because the bump stops are different colors does not mean one bump stop is better than the other. They're both very good bump stops, both will do a good job, and should be paid the same wages and have the same opportunities.

Sounds like a 1/2 ton plow truck? Can't say I've seen an Escalade with a plow on.

Yeah, I searched around, and it appears to be the way it is on all this era SUVs. Sits right on the control arm all the time.


Not in the rear, its floating on the air bags. Doing them anyways.
