The Innovators West dampers are a friction style damper. Inside the damper is a wet friction clutch pack assembly. Spring Loaded intertia rings work in conjuction with clutches to provide the dampening action. There is a small amount of fluid inside that acts as a lubricant as well as dissapates heat. The free floating clutch pack design allows for a broad dampening range in a small package.
All Innovators West dampers exceed the SFI 18.1 standards. A SFI sticker is placed on the damper as well as the SFI number is stamped into the back of the damper case.
Most dampers are marked every 5 degrees for 360 degrees and marked every 2 degrees from 30 degrees to 50 degrees. Serpentine dampers such as the Ford Mod Motor and GM LS dampers are not generally marked as the timing is computer controlled.
