Crankshaft Mandrel Kit (Chevy Big Block V8) (ALL31031) by AllStar Performance®. Mandrel Kit, which is made specifically for use with Allstar ALL31030 Crank Pulley, prevents mandrel bolt breakage. Mandrel is attached to the crankshaft pulley with three stock length bolts while the vibration damper is retained with the stock bolt. The mandrel bolt is then connected to the mandrel - not to the crankshaft - to reduce the possibility of engine harmonics loosening or actually breaking it. Kit includes all necessary spacers, pulley guides, and bolts to work effectively with most 3, 4, and 5 stage Dry Sump Pumps, alone or with belt driven fuel pumps. Pulleys sold separately. This premium product is the best way to go for those looking for the highest quality replacement that offers supreme levels of quality, performance and reliability. Designed to provide a perfect fit for a hassle free installation, this reliable product can help you get you vehicle back on the road faster and easier.
