Ford 351W Xtreme Roller Cam XR280R-10

The Ford 351W Xtreme Roller Cam XR280R-10 from COMP CAMS is a mechanical roller camshaft engineered for small block Ford engines demanding high-performance street and strip applications. This camshaft combines aggressive valve timing with roller follower technology to deliver increased horsepower and torque across a broad RPM band, making it an ideal choice for enthusiasts seeking measurable performance gains without sacrificing driveability.

The XR280R-10 features 0.608-inch intake lift and 0.614-inch exhaust lift with 280 and 286 degrees of duration respectively, optimized for operation between 2500 and 6500 RPM. The 110-degree lobe separation angle (LSA) provides a balanced overlap curve suited to street-driven builds, improving low-end response while supporting aggressive top-end power development. Mechanical roller technology reduces friction losses compared to flat-tappet designs, allowing the camshaft to achieve higher valve velocities with greater reliability and durability during extended high-RPM operation.

This cam is built for 351W-displacement Ford engines and is compatible with stock or upgraded valvetrain components within the mechanical roller specification. Users upgrading to the XR280R-10 should verify pushrод length, rocker arm geometry, and valve spring pressure to ensure proper clearances and avoid contact issues during valve operation. The Xtreme Energy series positions this camshaft as a proven option for Ford enthusiasts balancing performance, cost, and installation simplicity in rebuild or modification projects.
