Thumbnail Filmstrip of 7.3L Powerstroke Colt Cams Stage 2 Billet Camshaft - C-852-H Images
Unlock the true breathing potential of your 7.3L Powerstroke engine. Factory Ford camshafts were heavily restricted by 1990s emissions strategies, intentionally trapping exhaust gases inside the combustion chamber. This cylinder heat chokes airflow, creates lazy turbo spool-up on fixed-geometry turbos, and leads to dangerously high Exhaust Gas Temperatures (EGTs) under load or when towing.
The Colt Cams Stage 2 Billet Camshaft (Part # C-852-H) solves this factory bottleneck. Engineered in collaboration with elite diesel builders, this cam optimizes valve lift, duration, and lobe separation to thoroughly scavenge spent exhaust gases and pack cylinders with dense, clean air. The result is noticeably quicker spool times, lower operating temps, a wider powerband up to 5,000 RPM, and a clean, subtle performance idle.
Performance Highlights
100% Brand-New Billet Steel: Machined from raw billet stock—not a reground factory core. Zero core charge or return hassle.
True Drop-In Upgrade: Designed to work without machining piston valve reliefs or custom-length pushrods on factory-spec valvetrains.
Aggressive EGT Reduction: Superior exhaust scavenging vents heat out of the combustion chamber, protecting pistons and valves under heavy throttle or towing.
Faster Turbo Spool: Helps fixed-geometry and upgraded non-VGT turbos build boost hundreds of RPM sooner.
Extended Powerband: Cleans up high-RPM drop-off and supports sustained engine speeds up to 5,000 RPM.
Distinct Diesel Idle: Delivers a crisp, slightly noticeable performance idle lope without sacrificing street drivability.
