Detailed Application Information

VSR-515-S is a valve spring retainer used in the upper valve train to help preserve the correct relationship between the valve spring and valve hardware. Melling recommends using new retainers when installing reclaimed or new engine valves, which makes this part relevant during rebuilds, refreshes, and stock restoration work. The retainer is specified for many Chrysler, Dodge, and Plymouth engines across model years such as 1958-1979, with fitment including Dodge Charger, Plymouth Fury, and Chrysler 300 applications. Part number VSR-515-S is intended for stock-style engine service where OEM-level geometry matters.

Common Uses

• Replacing worn or fatigued valve spring retainers
• Restoring valve train geometry during engine rebuilds
• Servicing stock engine assemblies with OEM-style hardware
• Addressing valve spring retention issues in classic Mopar engines
• Supporting valve service when installing reclaimed or new valves

Installation Notes and Tips

Verify valve spring and retainer dimensions before installation, including inside diameter, outside diameter, and thickness. Confirm the outside clip style matches the existing valve spring hardware. Because fitment spans many classic Chrysler, Dodge, and Plymouth engines, compare the application details against the engine build rather than relying on vehicle name alone. Professional engine assembly practices are recommended for installation.
