This universal overhead valve spring compressor is to remove vale springs with overhead valves without removing the cylinder head. 

Works with most cars. Use on overhead cam engines (OHC), overhead valve engines (OHV) and the compound valve angle hemispherical combustion chamber heads like Ford (CHV).

• Offset jaws grip the valve spring in parallel compression
• Adjustable spring depth reach grips to fit many large and small spring applications.
• Knob action design for secure valve spring locking into the tool.
• Tool maintains constant length as spring is compressed.
• Use with 901DD or 2992D air hold fittings to keep valve in place.

Not suitable for deep pocket (seated) valve spring engines.

Caution: vehicle must be placed in park/neutral before applying air pressure, otherwise vehicle may move.

Keep hands clear of fan, belts and pulleys since slight crankshaft rotation will occur.
