Luk LSC274 Clutch Slave Cylinder

LuK LSC274 Clutch Slave Cylinder

The LuK LSC274 clutch slave cylinder is a hydraulic manual transmission component for select Chevrolet, Oldsmobile, Pontiac, and Buick applications. It is built for vehicles that use a hydraulic clutch release system and need consistent clutch actuation for normal pedal feel and shifting.

Key Features

• Hydraulic clutch slave cylinder for manual transmission systems
• LuK engineering backed by Schaeffler’s experience in clutch release systems
• Direct replacement format for listed vehicle applications
• Cross-references Monroe Shocks & Struts (e.g., 172286, 182286) for the same application
• Part number LSC274 for catalog lookup and fitment verification

Product Details

LuK has been involved in the transition from mechanical clutch release designs to hydraulic systems, and that background shows in the LSC274. This clutch slave cylinder is intended for manual transmission vehicles that rely on hydraulic pressure to release the clutch, helping restore proper clutch operation when the original unit is worn or leaking. It is listed for 1993-1994 Chevrolet Cavalier, 1992-1994 Oldsmobile Achieva, 1993-1994 Pontiac Grand Am, 1993-1994 Pontiac Sunbird, 1993 Chevrolet Corsica, 1990-1991 Pontiac Tempest, and 1988 Buick Regal. The LuK LSC274 is a practical replacement choice when servicing a hydraulic clutch release system on these platforms.

What It Helps Address

• Hard or inconsistent clutch pedal feel
• Hydraulic fluid leakage at the slave cylinder
• Incomplete clutch release during shifting
• Difficulty engaging gears in a manual transmission
• Loss of clutch hydraulic pressure

Installation Notes and Tips

• Verify the vehicle’s clutch release system before ordering; some applications reference LB163 for internal slave cylinders.
• Confirm the part number LSC274 against the vehicle’s original hydraulic clutch slave cylinder.
• Inspect the hydraulic line, master cylinder, and related seals during service to avoid repeat repairs.
• Bleed the clutch hydraulic system after installation to remove trapped air.

Quality Assurance

LuK is part of Schaeffler’s clutch and drivetrain expertise, with long-standing development experience in hydraulic clutch release systems. That engineering background supports consistent replacement quality for manual transmission service.
