DSX Tuning LSA/LT4 Lower Pulley

These lower pulleys are compatible with ATI part numbers 918854 and 918856 for the LSA and LT4 (Camaro/CTS-V only) damper. They are machined from 6061 aluminum and anodized for protection. The pulleys are available in five sizes: -230mm (9.06") [LSA 15%/LT4 12%] -235mm (9.25") [LSA 18%/LT4 15%]* -240mm (9.45") [LSA 20%/LT4 17%]* -245mm (9.65") [LSA 23%/LT4 20%]* -250mm (9.84") [LSA 25%/LT4 22%]* NOTE: The LSA idler relocation bracket is required for the 235mm through 250mm options - see "MAY WE SUGGEST" below. NOTE: The 9.84 can interfere with the sway bar on extreme suspension geometry events in LT4 ZL1s/CTS-Vs.
