About This Product

Zodiac diaphragm spring retaining ring. It holds the diaphragm spring in place inside the clutch assembly. It fits 1990 to 1997 Big Twins. It also fits Sportster models, Tube frame bikes, and XB and RS models. These rings can lose tension or get distorted when you pull the primary apart. Swap it out while you are in there to keep the clutch pack pressure consistent. It replaces OEM 37908-90. Sold individually.
