Review CUMMINS Cams Big Stick Camshaft 89-18 fits COLT

The Cummins C.343.S Colt Camshaft, also known as the "Big Stick" camshaft, is a performance upgrade for diesel engines commonly found in heavy-duty trucks and industrial applications. This camshaft is specifically designed for Cummins engines with a displacement of 5.9 and 6.7 liters, produced between 1989 and 2018.

The Big Stick camshaft is manufactured by Colt Cams, a reputable brand in the high-performance aftermarket industry. This camshaft is engineered to provide improved power and torque output, making it an ideal choice for those seeking enhanced engine performance for towing, hauling, or off-road applications.

This camshaft features a unique grind design that optimizes the intake and exhaust valve events. The intake duration is increased to allow for more air and fuel mixture into the cylinders, while the exhaust duration is shortened to promote faster exhaust gas expulsion. This results in better combustion efficiency, increased power, and improved engine responsiveness.

The Cummins C.343.S Colt Camshaft is made from high-quality materials for durability and reliability. It is manufactured using billet steel for the lobes and roller tips, ensuring consistent camshaft operation under heavy loads. The roller tips are also designed to minimize wear and provide a smoother operation compared to traditional flat-tappet camshafts.

Installing the Big Stick camshaft requires some degree of mechanical expertise and the proper installation tools. It is essential to follow the recommended installation procedure carefully to ensure proper clearance and timing. Improper installation can lead to engine damage and decreased performance.

In summary, the Cummins C.343.S Colt Camshaft is a high-performance upgrade for Cummins diesel engines, designed to deliver increased power and torque output for towing, hauling, and off-road applications. This camshaft is manufactured by Colt Cams using high-quality materials for durability and reliability, and it features a unique grind design for optimized intake and exhaust events.
