The Enginetech EPF613-HD is a bulk 200 pack of heat-treated valve keepers (also known as valve locks or valve spring retainer keepers) with a 1 square groove profile sized for 3/8" valve stems. Fits 1958-2000 American Motors/Chevrolet/Chrysler/Dodge 2.5L/3.2L/3.8L+ applications.
Important Notes
- Bulk 200 Pack for machine shops and rebuilders: covers approximately 6 complete 2-valve V8 engine rebuilds or 12 2-valve L4 rebuilds at two keepers per valve. Order additional packs for 4-valve-per-cylinder applications or higher volume.
- Two keepers per valve: keepers are split wedges that meet around the valve stem groove to form a complete collet, which locks the valve spring retainer to the stem. Always order in even quantities.
- Groove profile: matches a 1-square grooved valve stem. Keepers must match the count and shape of grooves on the valve stem exactly - a mismatch will prevent proper spring retention.
- Valve stem diameter: 3/8". Verify the OE valve stem diameter against the keeper spec before installation.
- Heat-treated for elevated hardness and resistance to groove deformation under sustained valve spring load. Suitable for performance, commercial, and heavy-duty applications where standard-hardness keepers would be marginal.
- Specified for performance engine applications - higher spring pressures and elevated operating RPMs are within this keeper's design envelope.
- Cross-references multiple OE and aftermarket part numbers - see the OEM Cross-References section below.
- Always verify the OE valve stem diameter, groove count, groove shape (round vs square), and cylinder head material against the original keepers being replaced before installation. Keeper profiles are application-specific and cannot be interchanged freely between engines.

Enginetech Valve Keepers (also called valve locks or valve spring retainer keepers) are precision-machined split wedges that lock the spring retainer onto the valve stem groove, holding the valve spring under preload and transmitting the spring force to the valve. Each valve uses two keepers that meet around the stem groove, so a single engine requires two keepers per valve (for example, a typical V8 with 16 valves requires 32 keepers). These keepers are supplied in bulk pack quantities for machine shops and rebuilders. Always verify the valve stem diameter, groove count, groove profile (round vs square), and cylinder head material against the OE specification before installation; keeper profiles are specific to each valve family and cannot be interchanged freely even between engines of similar displacement.
