GM ECOTECH Camshaft Kit XE264 HR-13

The GM ECOTECH Camshaft Kit XE264 HR-13 from COMP CAMS is a precision-engineered valvetrain upgrade designed for GM EcoTec engine platforms seeking enhanced performance and reliability. This kit addresses the stock camshaft's limitations by delivering improved lift, duration, and valve overlap characteristics that unlock hidden horsepower and torque across the RPM band.

COMP CAMS engineered the XE264 HR-13 profile to optimize EcoTec breathing efficiency, increasing valve event duration and lift over factory specifications to improve cylinder filling and scavenging. The camshaft is manufactured from durable chromium-molybdenum steel with precision-ground lobes that ensure consistent valve actuation and reduced wear on lifters and pushrods.

Enthusiasts and budget-conscious tuners benefit most from this camshaft kit when combined with intake and exhaust modifications, fuel system upgrades, and tuning to unleash its full potential. The HR-13 grind designation indicates a hydraulic roller-compatible design, integrating seamlessly with stock or upgraded hydraulic roller lifters for reliable performance.
