Stage 2 Builder Box Construction
Every Industrial Injection Stage 2 Builder Box begins with a carefully inspected engine block that undergoes precision machining and blueprinting processes. The cylinders are plateau honed using torque plates to ensure proper cylinder geometry and optimal ring sealing under operating conditions.
The rotating assembly is balanced to minimize vibration while maximizing durability under extreme cylinder pressure and horsepower levels. Wagler HD Forged Connecting Rods, Industrial Injection X Series Coated, Chamfered and Fly Cut Pistons, coated H-Series bearings, and the reinforced 14mm Gorilla Girdle create an exceptionally strong bottom end capable of supporting serious power.
The included Industrial Injection Stage 2 Camshaft is designed to maximize airflow, improve engine efficiency, and support increased horsepower throughout the RPM range. Combined with the HD modified cam bearings and precision-machined cam journals, this package is engineered for performance enthusiasts who demand the highest level of durability and power potential.
To further enhance reliability, this builder box includes a Premium Killer Dowel Pin (KDP) Kit. The Killer Dowel Pin upgrade addresses one of the most common failure points found in 12 Valve Cummins engines by permanently securing the factory alignment dowel, helping prevent catastrophic engine damage and providing added peace of mind for long-term operation.
