Tool Steel Heavy Duty Valve Spring Retainers
Past 4,500 rpm — especially behind a high-lift camshaft — the factory retainer becomes the weak link in the valvetrain. These tool steel retainers are built for that load and work with any Hamilton 24-valve spring.
Key Features
-
Built for 4,500+ rpm operation
-
Reduced mass for precise valve control behind aggressive cam profiles
- Tool steel construction — substantially stronger than stock
- Works with any Hamilton Dodge 24-valve spring
Good to Know
- Hamilton specifies these retainers whenever the 110 lb competition springs are used
- Locks are not included
- Cams running over .370" lobe lift warrant titanium retainers instead
Fitment
1998.5–2007 Dodge Ram 5.9L Cummins 24-valve and 2007.5–2018 Ram 6.7L Cummins running Hamilton 24-valve spring packages.
