XFI NSR 5.0L Modular 4V Cams

These billet hydraulic roller cams from COMP Cams® unlock a major power upgrade for the 2011+ Ford 5.0L engine.
Designed specifically for Coyote V8 applications, these camshafts are counter balanced and work with phaser limiters
to produce optimum safe power.
The larger than normal lobe size on the Ford OHC is unlike any other cam-in-block engine, and the dangerous harmonics that come with these bigger lobes must be addressed for high performance usage. By taking cutting-edge race technology and applying it to street applications, COMP Cams® has engineered these phaser-friendly cams with an exclusive integrated counter balance design that cuts down on vibrations and reduces overall harmonics to ensure a smoother operating valve train that was properly engineered for high lift, long duration valve motion at high RPM.

The Ford 5.0L camshafts from COMP Cams® are available for both naturally aspirated and supercharged engines, with three stages available in each series. All cams are No Springs Required. Optimized race and street profiles give you the power where you need it most, whether that’s maximized mid-range power and torque or increased top end horsepower.

COMP Cams® Phaser Limiters


The COMP Cams® Phaser Limiters for the 2011+ Ford 5.0L allow independent control over intake and exhaust centerlines and eliminate piston to valve clearance issues that can occur when using larger aftermarket camshafts in these engine. They physically limit maximum cam phasing to 25 crank degrees (12.5 cam degrees). Four separate phaser limiters, with the proper tuning software, allow the OEM computer to independently control intake and exhaust centerlines. Take full advantage of the benefits of Variable Valve Timing (VVT) when using aggressive aftermarket camshafts without needing to install custom pistons to eliminate valve clearance issues.

The locks for the 5.0L Coyote Modular V8 Engine allow fully adjustable locking over the OEM phaser range (50 degrees) by using a stock timing set, phaser system, bolts with special plugs and slotted degree plates. The locks are easy to adjust on the engine and include a 4 crank degree (2 cam degree) mark on the outer diameter for accurate adjustment.They allow aftermarket race cams to be physically degreed and locked to ensure adequate piston to valve clearance and precise centerline control at very high RPM under extreme conditions, independent of any computer or mapping.
Physically limit maximum cam phasing to avoid piston to valve clearance issues with aggressive cams
  • Four phaser limiters or locks offer precise, independent control over intake and exhaust centerlines
  • Phaser limiters physically limit cam phasing to 25 crank degrees (12.5 cam degrees) while allocating maximum intake advance and exhaust retard
  • Easily adjustable phaser locks allocate locking over the OEM phaser range (50 degrees)
  • Allows use of larger, more aggressive aftermarket camshafts in 2011 Ford 5.0L Modular V8 engines
