Valve springs are used to provide constant tension on the valves. Without them, the valves would make contact with the tops of the pistons and cause damage. It's a good idea to have your old valve springs checked by your machine shop to make sure that they have the correct spring tension. If they do not meet the correct specifications, you should replace them with new ones.
Note: Black Delrin protective cover that clips onto valve spring compressor tools. Provides protection against contact with cylinder head and sharp edges of the spring compressor. Fits most spring compressor types.
With this latest evolution to our Universal Valve Spring Tool we have added the ability to actuate the compression tube even in tight confined locations like under the cowl where the lever cannot be moved or may not even fit. By adding the ability to separate the lever from the compression tube anywhere along the bar you can compress the springs that are confined by brake boosters, AC housings or other factors by locating the lever along the bar where there is open space.
Access to valves in areas that are not in open areas with engine in vehicle
Valve springs can be depressed "remotely", depressor bar and compression tube are separate
Complete universal kit with multi adjustable points
No need to remove engine due to confined areas saving time
No other valve spring compressor is as universal and adjustable
Depressor tube slides easily to each valve location without changing settings
Rocker arms transfer the energy from the camshafts and/or pushrods, to the valves. One end is moved by the camshaft and/or pushrod, while the other side moves the valve stem - physically moving the valve up and down.
The rocker arm is used to actuate the opening of either the intake or exhaust valve. It is essentially a pivot operated by either the camshaft lobe or a pushrod.
