About This Product
These JIMS upper valve spring collars are machined from high-strength Chromoly to handle the demands of high-performance valvetrains. They are designed for spring diameters between 1.437 inches and 1.500 inches and feature a 10-degree angle for a perfect OEM-style fit. These collars are compatible with double springs with dampers and will fit all valve stem sizes. Fitment includes 1984 to 2004 Big Twins, Twin Cam B models, and 1986 to 2003 XL Sportsters. Sold as a set of four, these collars provide the durability needed for high-lift cams and heavy spring pressures, ensuring your valves stay exactly where they should be during high-RPM operation. They are a significant upgrade over stock components.
Manufacturer part number: 1374.
