What It Helps Address

• Clutch slip during acceleration
• Hard or inconsistent clutch engagement
• Release bearing noise or wear-related chatter
• Difficulty shifting caused by worn clutch components
• Judder or vibration from a deteriorated clutch disc or pressure plate

Installation Notes and Tips

Verify the 8-1/2 inch disc size, 14-spline count, and 1 inch input shaft diameter before installation. Inspect the flywheel surface, pilot area, and release system for wear before assembly, and replace any worn mating components as needed. Proper alignment during installation helps prevent clutch drag and premature wear.

Quality Assurance

LuK develops performance specifications as an original-equipment supplier and manufactures a high level of its own clutch content. That OE-focused approach supports consistent fitment and service quality for the listed applications.
