The XR265HR-15 Comp Cams camshaft is a high-performance upgrade for GM LS engines equipped with the XFI fuel injection system. This camshaft features a 265/265 duration at 0.050-inch lift in both the intake and exhaust lobes, delivering impressive power and torque gains. The 112-degree lobe separation angle is designed to improve cylinder filling and combustion efficiency, while the high-lift hipped profile provides excellent valve control and volumetric efficiency at high RPMs.
This camshaft is a hydraulic roller design, which means it uses hydraulic lifters to maintain consistent valve clearance throughout the engine's operating range. This results in reduced maintenance and longer engine life compared to traditional flat tappet cams. The roller camshaft also features Comp Cams' proprietary Xtreme Energy surface treatment, which provides increased durability and wear resistance.

It is compatible with factory-style valve springs and retainers, making installation easy and straightforward. However, it is important to note that this camshaft may require other modifications to the engine, such as upgraded valves and valve springs, to achieve optimal performance.
Overall, the XR265HR-15 Comp Cams camshaft is a high-quality, high-performance upgrade for GM LS engines. Its hydraulic roller design provides improved durability and maintenance-free operation, while its high-lift hipped profile delivers impressive power and torque gains at high RPMs. If you're looking to take your GM LS engine to the next level, this camshaft is an excellent option to consider.
