Thats what I was considering buying.

My dad did the bounce test and determined the springs were wore out lol

He said since he pushed it abd bounced the rear a bit, it stopped bouncing after about 2 bounces which he said was fine for a strut? But the spring helps control height? Idk how accurate that is though lol
