The brand new MP XHD springs I installed on my 1971 Challenger R/T didn't make it out of the driveway because the rear sat so low.
I wasn't rubbing on the tires but they were very close.
I couldn't imagine how low the car would have ended up when the springs sagged even more after a few years.

Luckily I am close enough that I was able to take them right back off and return them to Summit Racing.

I was told it is the correct "stock" factory ride height, which it might be, but most Mopars today aren't riding on short little 14" factory tires.

Good luck.
