Steve,....LUK( British) has been around for a long time, supplier to a lot of mostly european OEM's....good units, comparable to Sachs (German).....they are good units, if you can find an application to fit your mopar, which they have,.........the American mfg's were good, until they stated going offshore to China/ Mexico for mfg,.....unfortunately for our economy, but fortunately for our mopars, LUK and Sachs make premium units that will survive behind some serious HP,.......I prefer Sachs Kelvar discs, and Sachs (BorgBeck style) 3 finger pressure plates in the 2800 lb plus range, SM or BB blk application
