Breathe new life and reliability into your Ford Super Duty with the Colt Cams Stage 2 Billet Camshaft (Part # C-849-H). Purpose-built for 2003–2010 Ford 6.0L and 6.4L Powerstroke diesel engines, this upgrade is engineered to eliminate the severe factory valvetrain and airflow restrictions inherent in OEM Navistar engine designs.

Factory 6.0L and 6.4L camshafts were ground with heavy in-cylinder exhaust gas recirculation (EGR) strategies in mind, purposefully retaining hot exhaust gases inside the combustion chambers. This compromises cylinder filling, creates lazy spool-up—especially on upgraded non-VGT turbochargers—and generates excessive Exhaust Gas Temperatures (EGTs) under load. The Colt Cams Stage 2 profile completely changes the equation: by optimizing valve timing to aggressively scavenge spent exhaust and pull in dense, cool air, it dramatically drops EGTs, improves fuel efficiency, and broadens power delivery all the way to 5,000 RPM.

Key Performance Benefits

• 100% Brand-New Billet Steel: Machined from raw, virgin billet steel with a factory-sized base circle. Unlike reground factory cores, there is zero core charge, no return shipping hassle, and no compromised heat-treat depth.

• Deep Case Hardening: Undergoes a specialized heat-treating process engineered to penetrate up to 5x deeper than OEM factory cams, vastly improving lobe longevity and resisting premature roller lifter wear.

• Quicker Turbo Spool: Significantly accelerates boost ramp on stock VGT chargers and is practically mandatory for lighting larger fixed-geometry (non-VGT) single and compound turbos.

• Aggressive EGT Reduction: Thorough cylinder evacuation vents excessive heat out through the exhaust manifold, protecting your pistons and cylinder heads when towing or hauling.

• True Drop-In Replacement: Engineered to drop into factory-spec engines without requiring fly-cutting pistons or modifying cylinder heads.

• Smooth & Crisp Idle: Provides an efficient, crisp engine note with a smooth, streetable idle suitable for daily towing rigs, work trucks, and weekend race builds alike.

⚠️ Installation Notes & Recommended Valvetrain Upgrades

• Mandatory Roller Lifter Replacement: Never install a brand-new billet camshaft on used lifters. Roller needle bearings and lifter wheels wear over time; reusing old lifters can damage the new lobes and cause catastrophic engine failure. Always install a new set of OEM or SBI Heavy-Duty Hydraulic Lifters (SBI VL114).

• Fresh Cam Bearings: Ensure optimal oil pressure and journal life by installing a fresh camshaft bearing set during assembly (e.g., Mahle / Clevite SH-1996S).

• Valvetrain Reinforcement: If you are running high boost, upgraded injectors, or elevated RPMs, pair this camshaft with heavy-duty pushrods and upgraded valve springs to eliminate high-RPM valve float.

• Clearance Check: While designed as a drop-in camshaft on standard-deck engines, always verify piston-to-valve clearance during assembly if heads or blocks have been heavily machined.
