Crow Cams Standard Replacement GM Springs - Set of 16
Standard Replacement GM Springs - Set of 16 — 4931-16
Sixteen replacement springs for Holden/Chevrolet V8 applications. Each uses a single spring with a damper.
These are replacement springs rather than a universal upgrade for every cam profile. Check the exact cam’s spring requirement and measure the installed height before reuse of the existing hardware.
Applications and compatibility
This part is listed for the following engine and vehicle applications where the Crow camshaft or valvetrain package calls for this exact part number:
- Holden Commodore VN–VR — 5.0L EFI V8
- Holden Commodore VS — 5.0L EFI V8
- Holden Torana LH–UC — V8 applications
Compatibility is still determined by the complete cylinder-head and camshaft combination; vehicle model alone is not a substitute for checking the required spring, retainer, lock, lifter and rocker setup.
Installation checks
Measure installed height and verify seat/open pressure, coil-bind margin, retainer-to-seal clearance and guide/seal clearance on the actual cylinder heads. Match the spring to the exact cam profile rather than selecting by engine family alone.
