These are a fixed pulley without the clutch pack.
Some people prefer to run a fixed pulley rather than have a clutch pack on the Alternator to eliminate a part that can fail.
These are a direct Bolt in Unit, With the genuine plug, so they plug straight in.
These have been a VERY reliable Unit for us, And we are Very happy with their Performance.
