The Jesel CAAS63 Comp Rocker Arms for BBC engines, specifically designed for applications ranging from 396 to 502 cubic inches, are a testament to Jesel's commitment to crafting high-performance components. These rocker arms are engineered for use with 1.63-inch valve stems and shot peened for improved strength and durability.
The CAAS63 Comp Rocker Arms are constructed from 6061-T6 aluminum, a material known for its lightweight strength. This material allows for reduced rotating mass, which can contribute to improved engine performance and efficiency. The arms feature a compact design, with a reduced length and height compared to standard rocker arms, which can aid in reducing valve train inertia and promoting quicker valve movement.
The shot peening process applied to these rocker arms enhances their fatigue strength and wear resistance. This process involves blasting the surface of the arms with tiny steel beads, causing compressive stresses on the material's surface. This results in a strengthened, more durable component that can withstand the high-stress environments found in high-performance engines.
The Jesel CAAS63 Comp Rocker Arms are also designed with a high-flow, full-circle, roller tip. This design allows for smoother valve movement, reducing friction and promoting increased valve control. The full-circle tip also ensures consistent valve contact, which can contribute to improved engine performance and engine life.
In summary, the Jesel CAAS63 Comp Rocker Arms for BBC engines are a high-quality, performance-oriented upgrade for your engine. Their lightweight 6061-T6 aluminum construction, compact design, and shot-peened surface make them an excellent choice for demanding high-performance applications, while their high-flow roller tip ensures smooth, consistent valve movement for improved engine performance and longevity.
