Introducing the Power R-853-2 R-853 engine rocker arms, specifically designed for use in 1967 to 1972 AMC engines with displacements of 287, 290, 309, and 343 cubic inches. These rocker arms are a crucial component of your engine's valvetrain system, responsible for converting the reciprocating motion of the piston into the linear motion required to open and close the engine valves.

The Power R-853-2 rocker arms are meticulously engineered to provide superior performance, durability, and reliability. Each arm is precision-machined from high-strength steel, ensuring rigidity and stability under the extreme loads generated during engine operation.

These rocker arms feature a unique design with full-length roller bearings that provide an extensive contact area with the cam lobes. This design not only reduces friction but also eliminates the need for lifters, resulting in a simpler and more efficient valvetrain system. The bearings are made from a high-quality material that ensures long-lasting performance and durability.

The Power R-853-2 rocker arms are designed to be a direct replacement for the original equipment, making installation straightforward and hassle-free. Each rocker arm comes complete with the necessary hardware for installation, including new studs and nuts. Additionally, the rocker arms are designed to work with standard valve springs, ensuring compatibility with most aftermarket and performance springs.

In summary, the Power R-853-2 R-853 engine rocker arms are a high-performance, durable, and reliable solution for 1967 to 1972 AMC engines with displacements of 287, 290, 309, and 343 cubic inches. These rocker arms are meticulously engineered to provide superior performance, reduce friction, and eliminate the need for lifters, making them an excellent choice for both daily drivers and high-performance applications.
