This is a pair of newly machined all-aluminum adjustable cam pulleys for Fiat DOHC engines.
Intake cam has a backside guard, the exhaust pulley does not.
When used in conjunction with an auxiliary shaft pulley with front side guard, the belt is contained correctly.
As a result, these pulleys are applicable to 2000cc and 1800cc engines.
Be sure to check out the multiple pictures. If you've had the head or block shaved during a rebuild, you need an adjustable cam pulley to get your valve timing right!
Billet aluminum insert with lightening holes, six mounting screws to assure against slippage. You can find up to a 10% increase in HP and torque by having the valve timing properly set. Weighs only 16 ounces each!
New and unused.
