2JZ Timing Belt Tensioner Bracket

The Real Street Performance 2JZ Billet Timing Belt Tensioner Bracket, part number RS02-0002, is engineered for durability and precise operation. Constructed from robust 6061 aluminum, it incorporates an oil-impregnated bronze bushing to prevent galling, a common issue with similar materials that can lead to adhesion, binding, and seizing between sliding surfaces. This design ensures a long service interval. The bracket also features a steel insert for the factory hydraulic belt tensioner to ride on, and all tool paths are designed with the longest possible radii to maximize strength while maintaining OEM location fitment. The use of a well-constructed tensioner bracket is critical; failure can lead to the timing belt failing, or the bolt fusing to the tensioner and subsequently breaking. Such failures can result in catastrophic engine damage, including bent or broken valves and pistons. Installation recommendations include deleting the lock washer on the idler pulley and using a drop of red Loctite in its place. Applying grease to the shank of the bolt that holds the tensioner to the oil pump, and a dot of blue Loctite on the bolt's threads, is also advised to prevent oil seepage. The specified torque for installation is 28 lb/ft, and it's important to retain the factory washer situated between the oil pump and the billet tensioner bracket. This tensioner bracket is designed for 2JZ, 2JZGE, and 2JZGTE engines, specifically fitting Toyota Supra models from 1993 to 1998 (naturally aspirated and turbocharged variants), and 1997-1998 models. It is also listed for 1997-1998 Toyota Supra Turbo models.
