From the manufacturer
From Traditional Single Springs to our Breakthrough Conical Design: COMP Cams has a Performance Valve Spring for your Engine
A Quick Look at the Different Valve Spring Types
Single Valve Spring
- Traditional Valve Spring Design | Non-Tapered Shape | Lighter Loads at the Seat and Max Lift | Ideal for Hydraulic Flat Tappet Camshafts
Dual Valve Spring
- Traditional Spring Design - Two "Single Springs" inside one another for added Load at Seat and Max lift | Non-Tapered Shape | Heavier loads at Seat and Max lift than Single Valve Springs | Ideal for Solid Flat Tappet, Hydraulic Roller and less aggressive Solid Roller Camshafts
Triple Valve Spring
- Traditional Spring Design - Three "Single Springs" inside one another for Heavy Load at Seat and Max Lift | Non-Tapered Shape | Heavy loads at Seat and Max lift | Ideal for Solid Roller Camshafts
Beehive Valve Spring
- Modern Spring Design | Tapered Shape | Light to Moderate Loads at the Seat and Max lift | Ideal for Hydraulic/Solid Flat and Hydraulic Roller Cams | Higher RPM, Eliminates Harmonics, Better Heat Dissipation, Longer Lifespan
Conical/Dual Conical Valve Spring
- Breakthrough Spring Design | Tapered Shape | Moderate to Heavy Loads at the Seat and Max lift | Ideal for Solid Flat, Hydraulic Roller and Solid Roller Cams | Higher RPM, The Best Natural Frequency Damping, Superfinished Surface, Best Heat Dissipation, Longest Lifespan
COMP Cams has the Tools Needed to Make Spring Selection and Installation Easy

Valve Spring CompressorA necessity for any valve spring project, COMP has a selection of heads-on and heads-off compressors for most applications. Top sellers are our 5462 GM LS Compressor along with our 5337 SBC/SBF Compressor and the Heavy Duty 5333 Heads-Off Compressor |
Valve Spring Height MicrometerA requirement for checking installed height, our spring micrometers are accurate to 0.001". See 4950 for 0.600"-0.950" Beehive Applications, 4928 for 1.400"-1.800", 4929 for 1.600"-2.200" and 4930 for 1.600"-2.200" Height Beehive Applications. |
Dial CalipersA must-have for any tool chest, COMP offers a standard, analog caliper under 4908 that measures from 0-6.000" in 0.001" increments as well as a digital option under 5634 that measures from 0-6.000" in .0005" increments. Calipers are great for checking valve guide and spring pocket outer diameters, a must when looking at spring seats/locators, valve seals etc. |
Valvetrain Assembly SprayA great way to protect your springs, locks and retainers during the assembly process, COMP Cams Valvetrain Assembly Spray (Part # 106) delivers additional protection to the components while also easing installation. |
Proper Spring Handling
- Handle springs with care. Never place in a vise, grab with pliers or hit them with a hammer. This will damage the surface of the spring, which will cause it to fail.
- When separating double or triple springs, use only a durable plastic object that cannot harm the shot-peened surface of the spring.
- Valve springs are shipped with a rust preventative coating that should remain on the spring throughout engine assembly. Do not clean springs with acidic or evaporative cleaners. This causes rapid drying and promotes the formation of rust on the surface, which can cause catastrophic failures.
Checking Loads
- COMP Cams has matched each set of springs for load consistency. A variance of ±10% is acceptable for new springs.
- When checking the spring loads on a load tester measure and note the thickness of the retainer where the outer spring sits. Assemble the retainer on the spring and place on the base of the spring checker.
- Compress the spring to the desired installed height. This is the measurement between the top of the spring (on the bottom side of the retainer where the outer spring sits) and the bottom of the spring on the base.
Installation
- Before installing the spring on the cylinder heads, check the installed spring height. This is the distance from the bottom of the retainer to the surface where the spring rests on the head. First, install the valve in the guide, then install the retainer and valve locks. Pull the retainer tightly against the valve locks while holding the valve assembly steady. Measure the distance between the spring seat and the outside step of the retainer using your height micrometer (Part #4928 or #4929). After you have measured all the valves, find the shortest height. This will become the spring’s installed height on your heads. If your combination includes a dual or triple spring assembly, it will be necessary to allow for the inner steps of the retainer.
- It will then be necessary to use shims to obtain the shortest installed height (±.020" is acceptable) on the remaining valves.
- Before removing the retainers, measure the distance from the bottom of the retainer to the top of the valve seal. This distance must be greater than the lift of the valve. If not, the guide must be machined to avoid cam failure.
- Once the valve springs have been installed, it is important to check for coil bind. This means that when the valve is fully open, there must be a minimum of .060" clearance between the coils of both the inner and outer springs. If this clearance doesn’t exist, you must change either the retainer or the valve to gain more installed height, or change to a spring that will accommodate more lift or machine the spring seat for extra depth.
- Always check for clearance between the retainer and the inside face of the rocker arm. You should check to see that you have the proper rocker arm/retainer combination and correct rocker geometry.
- To aid in the engine break-in process, spray the springs, rocker arms and pushrods with COMP Cams Valve Train Assembly Spray (Part #106).
Breaking in a Spring
- It is important for new springs to take a heat-set. Upon initial start-up, limit rpm to 1500 to 2000 until the temperature has reached operating levels. Shut off the engine and allow the springs to cool to room temperature. This usually will eliminate early breakage and prolong spring life. After the spring has been broken-in, it is common for it to lose a slight amount of pressure. However, it should then remain constant unless the engine is abused and the spring becomes overstressed. If this occurs, the springs must either be replaced or shimmed to the correct pressure.
