Ive had my Marlin1200HD clutch in my truck since 2002. thats 9 long years of muddin, rock crawlin, snow, deep water, daily driving a 120 mile commute from 2002-2005, and hauled some INSANE loads of scrap metal on a trailer and it STILL performs flawlessly.
And let me tell you, you will either spin a tire or kill the engine when you slip your foot off the pedal.
