COMP Cams Camshaft Kit CS XR258HR-10

If you're looking to get more torque and better mileage out of your small block Chevrolet engine, this COMP Cams Xtreme Energy Hydraulic Roller Camshaft Kit is a solid choice. This kit is designed for OE roller small block Chevy engines from 1987 and newer, specifically those with 305 to 350 cubic inch displacements. It's a great option for stock or mildly modified combinations where you want improved performance without sacrificing drivability.

The XR258HR-10 camshaft features a 206-degree intake and 212-degree exhaust duration at .050 lift, which helps build strong torque down low and through the mid-range. This translates to a more responsive feel when you're accelerating, whether you're cruising around town or hauling a load. The kit includes the camshaft itself, a set of hydraulic roller lifters, a complete timing chain set, assembly lube, decals, and installation instructions, so you have the essential components to get the job done. COMP Cams is well-known for producing reliable valvetrain components, and this kit is built to last.

This kit is intended for use with factory roller camshaft-equipped engines, so it won't fit LT-1 or LS1 style engines. It's important to note that this part is not CARB approved and cannot be shipped to California. Always refer to the manufacturer's installation instructions for proper setup and break-in procedures.
