[1] Requires shorter serpentine belt. Goodyear pt #4060785 for accessories & 4040405 for AC.
[2] All hubs have 3/16 key @ std SB 10° location. Please note: 8 groove & 10 groove shell assemblies are available for supercharger applications. Consult your ATI salesman. #917017 (7 1/2” diameter, 8 groove, steel) #917075 (6 3/4” diameter, 8 groove, aluminum)
[3] Requires shorter belts: Gates #K060775 - 6 rib, Goodyear #K040405 - 4 rib

[6] Damper assemblies have all countersunk bolts so nothing protrudes past front of damper. If you have an older damper and are ordering a new shell assembly only, you must cut a .090” x 45° chamfer on the front of your hub. ATI can also perform this operation for $40.
[7] Dampers furnished with #916320 hub spacer. For ‘97 & up Camaro/Firebird or ‘96 & up Corvette engine with a reluctor wheel; discard spacer provided.
  [8] For hubs with a 6 hole bolt pattern and 2.25 seal, use hub #916049B for B body, 916048B for F body and 916096B for Y body.
[9] Hubs are made of heat-treated alloy steel.
[10] Washer #953070 is required with LT1 hubs and is shipped with dampers.

[12] Contact Lingenfelter for proper belt set-up.
[13] 2010 LS3 Corvette Grand Sport coupes w/Manual Transmissions come equipped with a Dry Sump system, so an LS7 style damper is required.
[14] For no A/C - Order Hub #916349D with pulley delete ring.
[15] Contains 60 durometer elastomers
[16] Non-removable AC-pulley - OEM Diameter

[1] No supercharger pulley supplied. Sold separately - see chart
[2] Damper assemblies have all countersunk bolts so nothing protrudes past front of damper. If you have an older damper and are ordering a new shell
assembly only, you must cut a .090” x 45° chamfer on the front of your hub. ATI can also perform this operation for $40 if you send your hub in.
[3] CTS-V is 10% UD - Use Duralast Part # 375K4 for AC pulley and Gates Part # K060806, 6 rib for accessory drive.
[4] For applications making over 20 lbs. of boost, ATI offers a stronger, heat-treated & double keyed hub. Available outright or as a $25 upgrade on new orders - #916032 for 918856.
