Detailed Description

Built for modern hydraulic clutch operation, the Luk CRS004 helps convert or replace cable-style clutch actuation with a cleaner hydraulic setup. By removing cable friction from the system, it supports smoother clutch engagement and can reduce clutch wear during normal driving. The compact design also suits increasingly narrow engine compartments found in many manual transmission vehicles.

This part cross-references Dorman - First Stop CC649008 and Sachs SPM001 for the same application. For buyers searching for a Ford Ranger clutch master cylinder and line assembly or a Ford Bronco II hydraulic clutch replacement, the Luk CRS004 provides the key components needed for service work on the listed vehicles.

What It Helps Address

• Hard or inconsistent clutch pedal operation
• Worn cable-actuated clutch hardware
• Hydraulic clutch system leakage at the master cylinder or line assembly
• Reduced clutch engagement smoothness
• Packaging constraints in tighter engine compartments

Installation Notes and Tips

Installation instructions are included. This assembly is not pre-filled and not pre-bled, so the hydraulic system must be filled and bled after installation. Verify connector style, reservoir placement, and vehicle fitment before installation on 1988-1991 Ford Ranger or 1988-1990 Ford Bronco II applications.

Quality Assurance

Luk supplies hydraulic release system components for manual transmission use, with a focus on replacing cable-operated clutch setups with hydraulic operation. The CRS004 is a new part built as a complete clutch master cylinder and line assembly with the listed included components.
