Assault Racing Sportsman Series roller tip rocker arms deliver superior performance for your Chevrolet 262-400 engine. Crafted from premium 4340 chromoly steel, these self-aligning rockers are significantly stronger than die-cast aluminum or stamped steel alternatives, minimizing flex during operation. The 1.5 ratio rockers feature an elongated pivot slot specifically designed to accommodate higher lift camshafts, while the roller tip design reduces friction and valve stem scrubbing against guides, unlocking additional horsepower. This complete set of 16 includes rocker pivot balls and polylocks—a superior alternative to standard lock nuts. Rated for up to 350lbs of open spring pressure, these rockers are versatile enough for street rebuilds or demanding performance applications including off-road, circle track, drag racing, and marine engines. The 3/8 stud size ensures compatibility with many popular Chevy small block applications, including 350 Vortec engines.
