This auction is for the disc 4. (Labeled 4-10) See my other auctions for other disc sizes. These are replacement parts for the 1090 model only. Will not fit the 552. Parts are used and in good working order. Real bowflex parts, not off brand or 3D printed. Each part will fit the right or left side. See You tube video for how to. Just be carefull not to lose the springs when you disassemble. Thank you for taking an interest in my auctions.
