Ford Small Block

1.60 ratio, 7/16" stud

Made from high strength 6061-T6 aluminum extrusions, each piece is precision CNC machined and finished by hand to ensure that our customers receive the very best Assault Racing has to offer. Assault Racing stud mount aluminum rockers are specially machined to allow for larger springs and retainers with full-cage friction reducing needle bearings for added durability. The nose rollers and shafts are Cr40 steel, heat-treated and hardened to minimize the wear that naturally occurs between the roller tip and the valve stem.

As with other Assault Racing products, these are in-stock for immediate delivery. All Assault Racing aluminum rockers come complete with poly locks at no additional cost.
