These lower pulleys are compatible with ATI part number 917315 for the C7 LT4 damper. They are machined from 6061 aluminum and anodized for protection.
Six titanium T45 flat head screws are available as an option for securing to the ATI damper. The 9.84 has been discontinued as an in-stock item, but we are still able to cut them on demand through our Anysize pulley option.
The pulleys are available in two sizes:
- 230mm (9.06") [LT4 12%]
- 240mm (9.45") [LT4 17%]
