Titan 1JZ/2JZ ARP 2000 Crank BoltTitan Motorsports has partnered with industry leading fastener manufacturer ARP to develop an upgraded crank bolt kit for the Toyota JZ engine. These upgraded units are manufactured using ARP 2000 material which offers a tensile strength of 220,000 PSI, over 45% stronger than the factory specified Grade 8 bolt. This increase in material strength is partnered with an oversized washer which is both thicker and larger in diameter to take advantage of the increased clamping load and to properly secure the damper to the crank over a larger surface area.
