Common Problems This Part Can Address

• Difficulty disengaging the clutch
• Hydraulic fluid leakage at the master cylinder
• Reduced clutch release performance during shifting
• Wear-related failure in the original clutch master cylinder

Installation Notes

Installation instructions are included. This unit is not pre-filled and is not pre-bled, so the hydraulic system must be filled and bled after installation. The push rod is included, but the clutch slave cylinder is not included. Verify the pushrod length note for applicable GMC Suburban and Yukon fitments, listed as 191.5 mm from tip to centerline of eye-end.
