Lunati Voodoo Roller Rocker Arms. Lunati Voodoo roller rockers are the toughest around--over 100,000 miles of high-rev engine testing proves it.Crafted from certified aircraft-quality, heat-treated aluminum, they're matched to massive, precision-ground trunnions for superior durability, and optimized rocker arm geometry evenly distributes the load for maximum strength. Voodoo rocker arms also utilize oversized needle roller bearings--the biggest in the business--for better load distribution and longer service life. Finally, they're black anodized and the distinctive Voodoo logo is laser-etched on--you'll want to leave your valve covers off!
