Andrews 48 Series Chain Drive Camshafts For Harley Twin Cam 2006-2017

Andrews 48: The Torque King for the Modern Twin Cam

The Andrews 48 Series Chain Drive Camshafts for 2006-2017 Harley models represent the 2026 pinnacle of “real-world” engine tuning. While many performance cams focus on high-RPM horsepower that is rarely used on the street, the 48 series is designed for the 95% of riding that occurs under 5,000 RPM. For the rider of a modern Street Glide, Ultra, or Heritage Softail, the goal is often to increase “pulling power” when the bike is loaded with gear or a passenger. Andrews addresses this by utilizing a specialized lobe profile that builds high cylinder pressure early in the stroke. This results in the immediate, “seat-of-the-pants” torque that transforms a sluggish stock bike into a high-output 2026 performer. For those seeking secure, industrial-strength utility, the Andrews 48 is the most reliable way to revitalize a Twin Cam 96, 103, or 110ci engine.

Precision Geometry and Valvetrain Harmony

What sets Andrews Products apart in the 2026 marketplace is their mastery of valvetrain harmonics. The 48 series features a smooth-ramp design that minimizes mechanical noise and reduces wear on lifters and rocker arms. Because these cams are optimized for stock compression ratios, they do not suffer from the “hard starting” issues associated with more aggressive racing profiles. They are ground from premium alloy steel billets and heat-treated to ensure the lobes maintain their profile through years of 2026 summer heat and high-mileage tours. The 48 series is specifically designed for engines using the 2007-style hydraulic cam chain tensioners, ensuring a perfect interface with your factory or Feuling oiling system. Every cam is dyno-tested and laser-inspected to guarantee that your Stage 2 build delivers consistent, reliable power every time you twist the grip.

Expert Installation & Performance Advice

As specialists in Twin Cam performance, we recommend the 48 series for any rider who finds themselves downshifting too often on the highway. Pro Tip: To maximize your 2026 torque gains, pair these cams with a 2-into-1 exhaust system like the S&S Sidewinder. Installation Note: While these are bolt-in cams, we always recommend checking vavle-to-piston clearance on 110ci CVO models due to their higher factory lift. Maintenance Note: When the cam chest is open, it is the professional standard to replace your inner cam bearings with high-performance Koyo/Torrington units for 2026 reliability. Safety Note: Upgrading to a 48 series cam significantly changes the air-fuel demand; a Stage 2 ECU recalibration using a Fuelpak FP4 or Dynojet Power Vision is mandatory to prevent lean-running conditions during summer rides.

The Professional Standard for Reliable V-Twin Torque

Choosing Andrews 48 Series Camshafts means investing in unmatched mechanical efficiency and riding enjoyment. It offers a unique combination of modern CAD-designed timing and a robust construction that honors the legacy of the Harley-Davidson brand. For the rider who wants a high-output 2026 presence and a flawless engineering finish, the Andrews 48 is the unmatched leader. Swap the cams, feel the torque, and ride the distance.
