Review PRW Rocker Arm 7/16 In Stud Mount 1.70 Ratio Roller Tip Steel Bbc fits SPORTSMAN

The PRW 68454717 rocker arm is a high-performance replacement part designed specifically for use in small block Chevrolet engines. This component is a crucial part of the engine's valvetrain system, responsible for transmitting the force from the pushrods to the rocker arms and ultimately to the valves.

This particular rocker arm is a sportsman type, which is suitable for applications where increased RPMs and horsepower are desired. It features a 1.70 ratio, meaning that for every degree of crankshaft rotation, the rocker arm moves the valve 1.70 degrees, providing more precise valve control.

The stud mount design of this rocker arm means that it is secured to the engine block using studs rather than bolts. The studs are 7/16 inches in diameter, ensuring a secure and reliable connection to the engine.

The PRW 68454717 rocker arm is manufactured using steel and features roller tips. Roller tips are a popular choice for high-performance applications because they reduce friction and wear compared to traditional flat-tipped rocker arms. The roller tips ride on the lifter bores in the engine block, providing a smoother and more efficient valvetrain operation.

In summary, the PRW 68454717 rocker arm is a high-quality, performance-oriented component designed for use in small block Chevrolet engines. Its sportsman design, 1.70 ratio, stud mount, and roller tips make it an excellent choice for applications where increased power and durability are required.
