Andrews

Andrews Performance Camshafts & Harley-Davidson Engine Parts

Andrews Products has been a recognized name in American V-twin performance since 1972. Based in Illinois, Andrews specializes in manufacturing precision-engineered camshafts, transmission gears, and related components for street and racing applications.

At Get Lowered Cycles, we carry selected Andrews parts for Harley-Davidson Milwaukee-Eight engines and older motorcycle applications. Our selection includes performance camshafts, Supervolt ignition coils, and valve spring components for Shovelhead engines.

Andrews Milwaukee-Eight Performance Camshafts

Upgrading the camshaft is a popular modification for Harley-Davidson Milwaukee-Eight engines. Andrews offers multiple camshaft profiles designed to improve engine performance across different RPM ranges and displacement configurations.

Selecting the correct camshaft requires consideration of engine displacement, compression ratio, valve spring compatibility, exhaust system, and intended riding characteristics.

Andrews Milwaukee-Eight camshaft options include the 485, M462, and M464. Each offers different valve timing and power delivery characteristics.

Andrews 485 Cam for Harley Milwaukee-Eight

The Andrews 485 is a performance-oriented chain-drive camshaft developed for compatible Milwaukee-Eight engines.

It is designed to deliver strong low- and midrange power, making it an option for riders seeking improved acceleration and everyday street performance.

Manufacturer specifications include:

• 0.485-inch intake and exhaust valve lift
• Chain-drive camshaft configuration
• Designed for use with compatible factory valve springs
• Performance-oriented operating range of approximately 1,500 to 5,600+ RPM
• Applications for selected Milwaukee-Eight engines starting at 107 cubic inches

Explore the Andrews 485 Milwaukee-Eight Camshaft.

Fitment varies by engine generation and motorcycle model. The newer Milwaukee-Eight configurations, including variable valve timing engines, require specific compatibility verification before ordering.

Andrews M462 Milwaukee-Eight Camshaft

The Andrews M462 is designed to improve low- and midrange engine performance on compatible Milwaukee-Eight motorcycles.

According to Andrews' product information, the M462 is a bolt-in camshaft developed for applications using compatible factory valve springs. Its intended power characteristics make it relevant to riders seeking responsive street performance rather than a camshaft focused exclusively on high-RPM horsepower.

Camshaft selection should account for engine displacement, compression, intake and exhaust modifications, and the desired powerband. Proper engine calibration is also important following installation.

Andrews M464 Milwaukee-Eight Camshaft

The Andrews M464 is another performance camshaft available for selected 2017-2023 Milwaukee-Eight engines.

Its design emphasizes midrange performance, particularly when combined with an appropriate exhaust system and engine calibration.

Different camshaft profiles produce different results depending on the engine combination. Compare the manufacturer's cam timing specifications and installation requirements rather than selecting a cam solely by its advertised lift.

Andrews Supervolt Ignition Coils

In addition to engine performance camshafts, Andrews manufactures Supervolt ignition coils for selected older Harley-Davidson ignition systems.

These replacement coils are designed to provide high-voltage ignition output while maintaining a traditional appearance suitable for older motorcycle applications.

Get Lowered Cycles carries selected Supervolt configurations, including:

• 2.8-ohm Red: Designed for specified electronic ignition systems.
• 4.8-ohm Black: Designed for specified points-type ignition systems.

Explore the Andrews Supervolt 2.8-Ohm Ignition Coil or the Andrews Supervolt 4.8-Ohm Ignition Coil.

Ignition coil resistance must match the requirements of the motorcycle's ignition system. Installing a coil with incorrect resistance can damage ignition components or cause improper operation.

Andrews Shovelhead Valve Springs & Retainers

Andrews also manufactures valvetrain components for older Harley-Davidson engines, including selected Shovelhead applications.

Available components include high-lift valve springs, upper spring collars, and lower spring collars for specified 1966-1984 Shovelhead engines.

These components can be useful during cylinder head rebuilding or when installing a compatible performance camshaft that requires changes to the valve spring arrangement.

Before selecting valve springs or retainers, verify the camshaft's required spring pressure, installed height, valve lift, coil-bind clearance, and compatibility with the cylinder head.

Older motorcycles may have aftermarket cylinder heads, valves, or previously modified components that affect compatibility.

Andrews Transmission Gears & Drivetrain Heritage

Andrews Products is also widely recognized for its transmission gears and drivetrain engineering.

The manufacturer offers transmission components for numerous Harley-Davidson platforms, including close-ratio gear sets and replacement transmission parts for compatible older motorcycles.

Andrews transmission components are engineered for specific transmission generations and gear ratios. Proper selection requires identifying the motorcycle's transmission configuration and the intended gearing characteristics.

Transmission gears are part of the broader Andrews manufacturing lineup, although availability through Get Lowered Cycles varies by product.

Choosing the Right Andrews Camshaft for Your Harley

Before selecting a performance camshaft, consider the following:

• Engine generation: Identify whether your motorcycle uses a compatible early Milwaukee-Eight engine or a newer generation with different camshaft requirements.
• Engine displacement: A camshaft intended for a relatively stock engine may perform differently in a large-displacement build.
• Compression ratio: Cam timing should complement the engine's compression and cylinder head configuration.
• Valve spring compatibility: Some camshafts work with factory valve springs, while others require additional valvetrain upgrades.
• Riding characteristics: Decide whether low-RPM torque, midrange acceleration, or high-RPM horsepower is your primary goal.
• Supporting modifications: Intake, exhaust, fuel delivery, and proper engine calibration influence the final performance results.

Andrews Products Frequently Asked Questions

Are Andrews camshafts made in the USA?

Andrews Products manufactures its motorcycle camshafts and transmission components in the United States. The company has specialized in performance motorcycle engine and drivetrain components since 1972.

What is a bolt-in Andrews camshaft?

A bolt-in camshaft is designed to work with specified factory engine components, potentially avoiding certain additional valvetrain modifications. However, bolt-in does not mean the installation requires no additional parts or engine calibration. Always follow the manufacturer's instructions.

What is the difference between Andrews 485, M462, and M464 cams?

These camshafts use different timing profiles and are intended to produce different engine performance characteristics. The 485 is designed for strong low- and midrange performance, while the M462 and M464 offer alternative profiles for compatible Milwaukee-Eight applications. Compare the manufacturer's technical specifications when making a selection.

Do Andrews camshafts require tuning?

Performance camshaft installations generally require appropriate engine calibration. Changes to valve timing can significantly affect airflow, fueling, and ignition requirements. Follow the engine and camshaft manufacturers' recommendations and applicable emissions regulations.

Will an Andrews cam fit a 2025 or 2026 Harley-Davidson?

Compatibility depends on the exact motorcycle, engine generation, and camshaft. Newer Milwaukee-Eight engines, particularly those equipped with variable valve timing, may require different camshaft components. Always verify manufacturer-approved fitment before ordering.

What is the difference between Andrews 2.8-ohm and 4.8-ohm ignition coils?

These Supervolt ignition coils are designed for different ignition configurations. The 2.8-ohm version is intended for specified electronic ignition applications, while the 4.8-ohm version is intended for specified points ignition systems. Always confirm the ignition system's required coil resistance.
