Prevent mandrel bolt breakage with Allstar Performance crank pulley mandrel kits. Designed specifically for Allstar crank pulleys, these kits provide you with all of the necessary components to connect the mandrel bolt to the mandrel—not the crankshaft—reducing engine harmonics to prevent loosening or breaking. The mandrel kits include all necessary spacers, pulley guides, and bolts to work with most 3, 4, and 5-stage dry sump pumps or belt-driven fuel pumps. (The crank pulley mandrel is also available separately, if desired.)
