Giggleschits

I’ve had these on for about 6 months now but I haven’t driven it a whole lot until now. I’ve got an 09 SS and I’m noticing that the rear shock/struts are extremely loud. Anytime I hit a bump there’s a massive clunk from the rears. The way the rears are set up is the strut then the sprint with a upper bump stop with the height adjustment and then you reuse your lower bump stop. I didn’t know if anyone had any experience with these and could shed some light on the sound or why it’s making it.
