Product Overview
Valve springs, seals, retainers, and lifter-related repairs often require spring removal without pulling the cylinder heads. This fixture uses the HEMI head geometry to compress a selected spring so the keepers can be removed under controlled pressure.
Compressed valve springs store dangerous energy, and the valve must be kept from dropping into the cylinder. Use the correct piston position or compressed-air method, wear eye protection, and follow the tool and engine service procedures.
Key Features & Performance
- Works with major Gen III HEMI engine sizes
- Allows valve-spring service with the cylinder head installed
- Useful for spring, retainer, seal, and cam-related work
- Positions over compatible rocker/shaft mounting points
- Workshop tool for repeated HEMI service
Common Uses
- Changing valve springs with the head installed
- Replacing valve-stem seals
- Servicing broken springs or retainers
- Accessing valvetrain parts during camshaft and lifter work

Compatibility Notice
Northline Parts does its best to list all known compatible models, but the correct part may fit an application not shown.

Frequently Asked Questions
Q: Can the valve fall into the cylinder? A: Yes. The valve must be supported by the specified compressed-air or piston-position method before the spring is removed.
Q: Is this safe for an untrained first-time repair? A: Valve springs store substantial energy; professional service is recommended if you are not experienced with valvetrain work.
Q: What should I compare before ordering? A: Match the HEMI generation, cylinder-head casting, rocker/shaft mounting geometry, engine size, and intended on-engine service procedure.
Q: Is this supplied by the original equipment manufacturer? A: No. This is a new aftermarket part. Brand names and reference numbers identify fitment only.
Package note: One valve spring compressor fixture is supplied with the fasteners and adapters shown.
