Rear shackle modification

Hey me too but the car is empty, so for ride height I loaded the car with pellet stove bags ,are they noisey ? Haven’t finished the car yet ? I’m thinking they will be .

The sliders? When I first installed them I heard them a few times when I was trying to listen to see if I could hear them. So I wouldn't exactly say they're noisy. But to be honest most of the time it's hard to hear anything over my exhaust, my stereo, and the ringing in my ears. :D
