$94.99

When a clutch master cylinder starts to leak or lose pressure, clutch engagement gets vague and shifting turns difficult. The Dorman - First Stop Clutch Master Cylinder CM640006 is a direct-fit replacement that converts clutch-pedal force into hydraulic pressure, sending fluid on to the release mechanism to disengage the clutch. It drops in on the 2001-2002 Ford Ranger (All), 2001-2011 Ford Ranger (L4-2.3L), 2001 Ford Ranger (L4-2.5L), 2001-2008 Ford Ranger (V6-3.0L) and 2001-2011 Ford Ranger (V6-4.0L), plus the 2001-2004 Mazda B2300 (L4-2.3L), 2001 Mazda B2500 (L4-2.5L), 2001-2004 Mazda B3000 (V6-3.0L) and 2001-2004 Mazda B4000 (V6-4.0L).
