Feuling HP+ 574 Camchest Kit For Harley Twin Cam 2006-2017

Feuling HP+ 574: Re-Engineering the Twin Cam Heart for 2026

The Feuling HP+ 574 Camchest Kit for 2006-2017 Harley-Davidson Twin Cam models represents the 2026 pinnacle of valvetrain and lubrication synchronization. For many Twin Cam owners, the factory oiling system is the “weak link” that leads to excessive top-end heat and mechanical noise. Feuling addresses this by providing a total cam chest solution. The 574 camshaft is a highly versatile “Reaper” series grind that provides a wicked increase in power from 2,100 to 5,700 RPM. Because it is designed to work with stock valve springs, it is the ultimate high-performance 2026 bolt-in solution for 96″, 103″, and 110″ engines. For the rider seeking secure, industrial-strength utility and an engine that stays cool under the most demanding 2026 conditions, the Feuling HP+ 574 kit is the definitive choice.

Superior Scavenging and Structural Integrity

What sets the Feuling HP+ kit apart in the 2026 marketplace is the legendary Feuling High-Flow Oil Pump. In the high-output 2026 environment, oil management is everything. This pump increases oil pressure and scavenging volume significantly, which reduces “sumping” and lowers oil temperatures by up to 30 degrees. This increased flow ensures that your lifters stay pumped up and your piston cooling jets are operating at maximum efficiency. The included HP+ Billet Cam Plate is machined from 7075 aluminum, which has a thermal expansion rate much closer to the engine cases than stock cast plates. This ensures the high-output 2026 presence and mechanical synchronization required to eliminate the “ticking” often heard in performance Twin Cams. This kit is a complete engineering upgrade that protects your investment while delivering massive power gains.

Expert Installation & Performance Advice

As specialists in Twin Cam valvetrain architecture, we recommend the 574 kit for riders who want “big-cam” power with “stock-like” reliability. Pro Tip: To truly maximize the 2026 potential of the 574 cams, pair this kit with a high-flow intake and 2-into-1 exhaust to allow the cams to breathe properly. Installation Note: Always check your inner cam bearings during installation; we highly recommend upgrading to full-complement Timken bearings for the 2026 season. Maintenance Note: Use a high-quality 20W-50 synthetic oil and change the filter after the first 500 miles of 2026 break-in to ensure the new cam surfaces seat perfectly. Safety Note: Upgrading to a 574 cam requires a professional fuel map recalibration via Dynojet Power Vision to ensure your 2026 engine remains bulletproof and powerful.
