COMP Cams XR265HR LS Camshaft – 54-412-11

A proven LS1 & LS2 camshaft upgrade delivering strong low-end torque and excellent mid-range power. The COMP Cams XR265HR LS cam is a popular choice for street driven Holden LS1, LS2 and LS3 engines wanting improved performance without sacrificing drivability.

This Comp Cams LS camshaft works well with factory combinations and has been successfully installed by many customers using the standard factory torque converter. In many cases the engine will run from factory tune settings. We do recommend a custom tune to maximise power, drivability and throttle response.

While this LS1 cam upgrade can operate with standard valve springs, upgrading the springs will allow the camshaft to achieve its full RPM potential and improve long term valvetrain stability.

Total Performance has had strong feedback from customers running this camshaft in Holden Commodore LS1 applications, making it a solid choice for street performance builds.
