LuK (UK) Ltd has now established itself as a European manufacturing centre of excellence for both car and tractor clutches.

LuK was the first clutch manufacturer in Europe to introduce the diaphragm spring clutch. Today the diaphragm spring has almost completely replaced the traditional coil spring in passenger cars, light trucks and tractors. LuK builds some eight million diaphragm spring clutches annually and supplies them to virtually all major automotive manufacturers worldwide.

The diaphragm spring clutch has been so successful for many reasons. Its simple rotationally symmetrical design and low axial length make it easier for automotive designers to fit the clutch into today's restricted engine compartments. The diaphragm spring fingers also perform the release function. In spite of high clamp load requirements, the spring's progressive characteristic curve provides the low release loads demanded by today's comfort-minded drivers.

When coupled with an appropriately tuned cushion characteristic in the clutch disc, the diaphragm spring offers excellent engagement performance and exceptional start-up comfort.
