Single Disc Organic: Aftermarket organic clutches are generally better than the OEM clutch you get from your dealer. This is due to the better quality materials used, the quality of the manufacturing process, and QC. Some companies also offer higher plate loads as options to the standard plate thus giving the clutch better holding ability than its OE counterpart. Best suited to trucks without or only minor power modifications.
