LS3 HYD ROLLER CAM XR281HR13 228/240°@50 .571/590″ 113°

Description

Maximize your engine’s performance with the LS3 HYD Roller Cam XR281 HR13, designed to deliver precise valve control and improved power output. This camshaft addresses the critical need for efficient air-fuel mixture management, resulting in enhanced combustion and torque across the RPM range.

Featuring a duration of 228/240° at 50% lift, this camshaft ensures optimal valve opening times that allow better cylinder filling and exhaust scavenging, directly improving horsepower and throttle response. The lift specifications of .571/.590″ provide increased valve travel, which translates to greater airflow and improved volumetric efficiency.

Engineered by Comp Cams, a leader in performance camshafts, this model uses hydraulic roller technology to reduce friction and wear compared to flat tappet designs. The hydraulic lifters maintain zero valve lash, offering smoother operation and reduced maintenance requirements, which means longer intervals between adjustments and enhanced engine reliability.

Constructed with precision machining and high-strength materials, the camshaft weighs 5.64 kg and measures 59.20 cm in length, 6.60 cm in width, and 8.00 cm in height. These dimensions ensure compatibility with LS3 engine platforms while maintaining structural integrity under high stress and RPM conditions.

Its 113° lobe separation angle balances performance and drivability, reducing overlap to minimize emissions and improve idle quality without sacrificing power. This precise calibration makes it ideal for enthusiasts seeking a blend of street-friendly manners and track-capable performance.

Installation of the LS3 HYD Roller Cam XR281 HR13 offers significant gains in engine responsiveness and efficiency, making it a critical upgrade for LS3 engines aiming for higher output and durability. The combination of advanced hydraulic roller technology and optimized cam timing positions this camshaft as a superior choice for serious engine builders.

Invest confidently in a camshaft that delivers targeted performance improvements backed by Comp Cams’ engineering expertise, ensuring your LS3 engine performs at its peak with consistent reliability and precision.
