Review SPEEDMASTER Outlet Ford 289 Windsor Shaft 1.6 Ratio Dna Aluminum Roller Rocker Arms fits SB 302 351

The Speedmaster Outlet 840136501770 is a set of roller rocker arms designed specifically for Ford SB 289, 302, and 351 Windsor engines with a shaft size of 1.6 inches. These roller rocker arms are an essential upgrade for any Ford enthusiast looking to improve the performance and reliability of their engine.

Each roller rocker arm is meticulously crafted to provide a perfect fit and superior functionality. The arms are made of high-quality steel, ensuring durability and resistance to wear and tear. The roller tips are made of hardened chromoly steel, which is known for its strength and ability to withstand the extreme pressures generated by high-performance engines.

One of the most significant advantages of these roller rocker arms is their use of DNA technology. DNA technology is a proprietary manufacturing process that allows for the precise control of rocker arm geometry, ensuring optimal valve control and combustion efficiency. This results in improved power output, increased fuel efficiency, and reduced emissions.

The roller rocker arms feature a roller bearing design, which reduces friction and wear on the camshaft lobes and lifters. This results in smoother engine operation, reduced engine noise, and longer camshaft and lifter life. The bearings are also self-lubricating, eliminating the need for regular maintenance and reducing the risk of engine damage due to dry bearing conditions.

Installing the Speedmaster Outlet 840136501770 roller rocker arms is a straightforward process, making them an excellent choice for both professional mechanics and enthusiasts working on their own engines. The kit includes all necessary hardware for installation, ensuring a hassle-free experience.

With their superior quality, DNA technology, and easy installation, these roller rocker arms are sure to provide significant performance improvements and increased reliability for your Ford engine.
