Andrews Evolution Cams Camshafts for Harley Davidson EVO 84-99

Andrews Products high-performance camshafts are designed using advanced computer technology to deliver the ultimate balance of performance and reliability. Engineered for Harley-Davidson Shovelhead and Evolution Big Twin engines, these cams are manufactured from premium alloy steel billets and undergo rigorous heat-treating processes to ensure long-lasting durability.

Whether you are looking for a bolt-in street cam to improve mid-range torque or a high-lift grind for modified racing motors, this selection of camshafts offers versatile powerband options ranging from 1,500 to 6,500+ rpm. Many of these grinds are designed to work seamlessly with stock springs and hydraulic lifters, capable of reaching 6,000-plus rpm without valve float. Selected profiles also feature fast open and close ramps to provide crisp throttle response and cooler operating temperatures.

Key Features:

• Computer-designed profiles for maximum performance and reliability.
• Manufactured from high-grade alloy steel billets.
• Options available for stock, modified street, and touring applications.
• Capable of 6000-plus rpm with stock springs (depending on specific variant).
• Compatible with both carbureted and fuel-injected models.
• Made in the U.S.A.

Technical Note: Installation requirements vary by profile. While many are "bolt-in" applications, high-lift variants may require high-lift springs and titanium collars. Always check for coil bind, valve-to-valve clearance, and valve-to-piston clearance during installation. Suitable for use with hydraulic lifters.

Compatibility:

Fits 1984-1999 Evolution Big Twin models. Please refer to specific variant specifications for timing, duration, and lift attributes to match your engine requirements.
