Introducing the new and improved Lunati Voodoo Aluminum Roller Rocker Arms. The product of extensive testing, these CAD designed and FEA optimized rockers were engineered specifically for high performance street engines. Constructed from extruded aircraft quality aluminum and CNC machined to precise tolerances, the superfinished surface increases durability and sheds oil. They are lightweight yet strong enough to handle aggressive spring pressures and higher lift cams while featuring optimized balance of strength and reduced moment of inertia. The clipped trunnion is secured to ensure positive side-to-side location and the precision sorted needle bearings allow the rocker to withstand higher valve spring pressure. Finally, these rocker arms are clearanced for higher lift springs and camshafts.
Available in a variety of ratios and diameters for Chevy, Chrysler and Ford Small and Big Blocks, as well as Olds and Pontiac applications.
