GEN 5 DOD Conversion Truck Cam 6.2L L86

The GEN 5 DOD Conversion Truck Cam 6.2L L86 from Brian Tooley Racing is engineered for GM truck owners who want to eliminate cylinder deactivation while maximizing engine efficiency and reliability. This conversion camshaft replaces the factory cam that controls the DOD (Displacement On Demand) system, allowing you to run a traditional fixed-valve operation on your 6.2L L86 engine. Built for serious enthusiasts who understand that DOD systems can compromise oil pressure, valve train durability, and overall engine longevity under sustained performance driving or towing.

Brian Tooley Racing's conversion cam is precision-manufactured to OEM specifications while eliminating the complexity of lifter deactivation mechanisms. The design maintains proper valve lift, duration, and timing geometry to ensure consistent combustion and thermal management across the entire RPM band. By converting away from DOD, you reduce parasitic losses associated with the solenoid valve system and achieve more stable oil pressure curves—critical for high-mileage trucks or those running upgraded cooling and lubrication systems. The cam profile is optimized for both stock and mildly modified builds, delivering improved reliability without sacrificing daily drivability.

Truck owners running Silverado, Sierra, or Tahoe platforms with the 6.2L L86 engine will find this conversion essential when upgrading fuel systems, tuning, or addressing DOD-related failures. Installation requires removing the valve cover and timing cover—a task best performed by experienced mechanics or shops familiar with GM cam replacement. Pair this camshaft with a quality tune that disables DOD codes to ensure reliable cold starts and proper engine management. This is the ideal choice for those committed to long-term reliability and consistent engine performance in both street and light-duty work environments.
