COMP Cams Ultra Pro Magnum XD Roller Rocker Arm Ratio Ford Small Block

COMP Cams Ultra Pro Magnum XD roller rocker arms are high-performance roller rockers for Ford small block engines. They are built for street performance, street/strip, and racing use. The roller tip and roller fulcrum design reduces friction and valvetrain wear, and it helps the valves open and close accurately. Use them as an upgrade over stock stamped rockers or as part of a camshaft and valve spring upgrade.

Key Features:

• Extruded aluminum body: Gives the rocker strength and rigidity under high spring pressure and RPM, while keeping the weight low.
• Roller tip design: Reduces friction at the valve tip, which cuts side loading on the valve guide and improves valve guide life.
• Roller fulcrum: Needle bearing construction reduces friction and heat in the pivot area for smoother operation.
• Hardened, precision-machined components: Made for durability in demanding, high-lift applications.
• Multiple rocker ratios available: Pick the ratio that suits your camshaft and valvetrain setup to get the lift you want.

COMP Cams is a well-known name in camshafts and valvetrain components, and the Ultra Pro Magnum XD line reflects that experience. These rocker arms can help you get more valve lift, better throttle response, and stronger power from your Ford small block build.
