Did you know that if you ever have to lift the rear of your Challenger, Dodge provides a convenient rubber lift point (see photo circled on the right)?
i don't recall seeing that rubber snubber on mine at all. I know there is a pocket for the rear lift point and that is where I put my jack.
I have a 2015 and that's exactly how mine looks. Except on one side I got that triangular shape piece caught on a concrete block that was sticking out of a dirt driveway. Almost Ripped it off completely. Just kinda pushed it back in place.
Same parts on my car. Just swapped out factory rotors for drilled slotted. What a pain in the hand it was a true knuckle buster .
