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.
