Product Details

This COMP Cams XFI XE-R 232/234 Hydraulic Roller Camshaft is designed for GM LS GEN III and IV engines, specifically targeting standard displacement LS1 and LS6 applications. You'll receive the camshaft itself, ready for installation into your engine build. This camshaft is a popular choice for those looking to get more out of their LS-based engine, whether it's in a performance car like a Chevrolet Camaro or Corvette, or a truck like a Chevrolet Silverado or GMC Sierra.

The XE-R designation signifies an updated lobe design that offers improved performance over previous generations. This camshaft features a 232 degrees of intake duration and 234 degrees of exhaust duration at 0.050 inch lift, with a 112-degree lobe separation angle. These specifications are chosen to provide a noticeable increase in horsepower and torque, especially in the mid-range and upper RPMs, while still maintaining reasonable drivability for street applications. It's a well-built component intended to raise the performance ceiling of your engine.

When installing this camshaft, it's important to ensure you have the correct supporting components. This includes a compatible valvetrain, such as upgraded valve springs, pushrods, and lifters, to handle the increased lift and duration. Always refer to the manufacturer's installation instructions for specific details and recommendations to ensure proper fitment and optimal performance from your new camshaft.
