Description
Valve keepers are critical to preventing catastrophic valve float and spring failure under high RPM conditions. If you’re running JIMS titanium valve spring retainers on your Big Twin, using matched valve keepers ensures the lock angle seats properly and maintains reliable valve train geometry. These keepers are essential for any serious engine build where precision and durability directly impact performance and engine longevity.
