Review JESEL Shaft Mount Rockers Sbc Afr Pre 220 Heads fits ELIMINATOR

The Jesel KSS-375050 Shaft Mount Rockers are a high-performance accessory designed for use with AFR Eliminator 220 heads. These rocker arms are part of Jesel's KSS (Kevlar-Spring-System) series, which offers several advantages over traditional spring-loaded rocker arms.

These shaft mount rockers are manufactured from 6061-T6 aluminum, a strong and lightweight material that ensures durability and reliability. The arms are designed to be used with Jesel's Kevlar springs, which provide consistent force and eliminate the need for adjustments due to spring compression.

The KSS-375050 rockers feature a shaft diameter of 0.625 inches and a length of 2.375 inches. The arms have a 1.125-inch tip diameter, which ensures adequate clearance for larger valves and combustion chambers. The arms are also designed to work with Jesel's adjustable cam gears, allowing for precise valve lash adjustment.

One of the key benefits of the KSS-375050 Shaft Mount Rockers is their smooth and consistent valve operation. The use of Kevlar springs eliminates the need for heavy coil springs, reducing friction and wear on the valves and other components. This results in better engine performance and longer component life.

Another advantage of these rocker arms is their ease of installation. The shaft mount design allows for quick and easy installation, and the adjustable cam gears make valve lash adjustment a simple process. The arms also come with bearing inserts, ensuring a proper fit and reducing the need for additional components.

In summary, the Jesel KSS-375050 Shaft Mount Rockers are a high-quality and high-performance accessory for use with AFR Eliminator 220 heads. Their lightweight design, consistent valve operation, and easy installation make them an excellent choice for engine builders and racers looking to maximize engine performance and reliability.
