202/211 Duration - Torque-Optimized:

The Torque cam features 202° intake and 211° exhaust duration measured at .050" lift. This mild duration is specifically optimized for low-end torque and towing applications, providing strong performance where trucks need it most - at low RPM. The slightly longer exhaust duration helps scavenge exhaust gases efficiently while maintaining excellent low-end torque.

.550/.550 Lift - Mild Performance:

The .550" lift on both intake and exhaust valves provides a good balance of performance and reliability. This moderate lift may work with stock valve springs (though upgraded springs are recommended), and it doesn't require extensive piston-to-valve clearance work. The lift is aggressive enough to provide noticeable gains while remaining conservative enough for daily driving and towing.

111° LSA - Torque-Focused:

The 111° Lobe Separation Angle is optimized for low-end torque and towing applications. This tighter LSA helps build cylinder pressure at low RPM, resulting in strong torque delivery for towing and acceleration. The LSA maintains a smooth, nearly stock-like idle while delivering improved performance throughout the RPM range.

Torque Cam - What to Expect:

• Idle: Smooth, nearly stock-like - minimal lope
• Low-End: Strong torque delivery - excellent for towing
• Mid-Range: Improved power and throttle response
• Top-End: Pulls to 5,800+ RPM
• Sound: Slightly more aggressive than stock, but very mild
• Drivability: Excellent - perfect for daily driving and towing
• Fuel Economy: Improved over stock with proper tuning

Perfect for Towing and Daily Driving:

The Torque cam is specifically designed for truck owners who use their vehicles for towing, hauling, and daily driving. Unlike aggressive performance cams that sacrifice low-end torque, the Torque cam maintains and improves low-end performance while adding power throughout the RPM range. This makes it perfect for:

• Towing trailers, boats, and campers
• Hauling heavy loads
• Daily commuting and family use
• Work trucks requiring reliable performance
• Anyone seeking improved performance without sacrificing utility

Improved Fuel Economy:

With proper tuning, the Torque cam can actually improve fuel economy compared to stock. The more efficient combustion and improved airflow allow the engine to make the same power with less throttle input, resulting in better MPG during highway cruising and light-load driving.

Stock Valve Springs May Work:

The moderate .550" lift means stock valve springs may work with the Torque cam, though BTR recommends upgrading to their valve springs for improved reliability and performance. If you're on a tight budget, you can potentially run stock springs initially, but upgraded springs are recommended for long-term reliability.
