Upgraded 16mm Miata Crankshaft Pulley Bolts

When used in racing situations with high RPM, the 4 small crankshaft pulley bolts are known to be a weak point. The factory bolts often break. These replacement bolts are manufactured by ARP and are much stronger than the oem bolts. Over the years, Mazda used various suppliers for the pulleys. There is no realistic way to know which design pulley you have on your engine. The only sure fire method is to remove one of the bolts and measure the "under head" length. The bolts are either 16mm (approx 5/8") or 25mm (approx 3/4"). Please make sure you measure the UNDER THE HEAD length to get the proper bolt kit. Bolts are sold in packages of 4

Price will be for a package of 4 bolts
