Product Details

LuK has extensive experience in hydraulic clutch release systems, and the LMC203 reflects that background with a service replacement focused on restoring clutch pedal hydraulic function. This part number is used in manual transmission applications where the master cylinder transfers pedal movement into hydraulic pressure for clutch engagement and release. The LMC203 cross-references AMS Automotive M0108 and Dorman First Stop CM39723 for the same application. For Jeep Cherokee and Jeep Wagoneer service, the LMC203 is a direct-fit style replacement for the listed model years.

What It Helps Fix

  • Soft or inconsistent clutch pedal feel
  • Loss of hydraulic pressure in the clutch release system
  • Difficulty disengaging the clutch
  • Fluid leakage at the master cylinder
  • Clutch pedal travel problems caused by a worn hydraulic master cylinder
