    OE Replacement Clutch Kits

 

Quality

The centerpiece of the KNAT Clutch Products Program is its OE Replacement Clutch Kits.  No other clutch kit supplier can offer components that exceed the OE quality that KNAT offers.  Many program repackagers do not offer high percentages of OE specified clutch covers and discs.  You can expect long life and smooth engagement from KNAT’s clutches because of our focus on quality. 

Value

KNAT’s kits contain every component that a technician needs to change out a clutch.  Each kit contains a clutch disc assembly, pressure plate cover assembly, release bearing, alignment tool, grease pack, and installation guide.  Also included when necessary are a pilot bearing, and technical service bulletin.  Some kits also come with a flywheel.  KNAT’s numeric, user-friendly part numbers have been designed to support the marketplace. 

Packaging

KNAT’s clutch kits use packaging that is state of the art to ensure that the product arrives and remains free of damage right up to the time it is installed in a vehicle.  The extra durable locking tabs ensure product security within its packaging until it is removed for final installation.  Our kits are packaged in an attractive, reinforced box that includes hand held slots for the heavier kits.  Other features of the packaging include: re-sealable foam insert for enhanced box and component protection, and a smart label where the part number is coded for size and vehicle make, shown vertically and horizontally with competitor interchanges. 

Exceptional Coverage

KNAT offers new clutch kits for over 30,000 vehicle applications in North America.  KNAT is the quality clutch supplier worldwide to the Original Equipment Manufacturers.  KNAT is also the world leader on clutch disc facings.  Our kit range covers over 50 model years and about 50 vehicle makes from domestic to import.  KNAT clutch kits are OE Engineered…Aftermarket Delivered!
