They feature a 10-degree angle for a perfect OEM-style fit and are compatible with double springs that include a damper. These collars work with all valve stem sizes and are intended for spring diameters between 1.437 and 1.500 inches. This set of four is an essential upgrade for any high-revving Harley engine where every gram counts.
