As part of the hydraulic clutch release system, the LuK LSC337 clutch slave cylinder for the 1998-2018 Subaru Forester 2.5L and other vehicles carries pedal movement to the clutch.
Before you replace the slave cylinder, rule out the clutch master cylinder, a leaking hydraulic line and air in the system, since any of them can also make the pedal feel soft. A pedal that sinks or trouble selecting gears can point to a worn slave cylinder.
The 1998-2010 Subaru Impreza 2.5L and 2000-2009 Subaru Outback 2.5L are among the vehicles this part fits, and it fits more besides. Open the Buyer's Guide tab to check your exact model and engine.
In the box: one clutch slave cylinder. The vehicle takes one.
Interchange: RN-074

What is the travel sensor LuK builds into its slave cylinders where needed for?
