AISIN Fan Pulley Bracket FBT-002 for Lexus GX470/LS400 & Toyota 4Runner Tundra — Die-Cast Aluminum, OE-Match Bearing

AISIN GENUINE FBT-002 Fan Pulley Bracket is an original-equipment–matched replacement bracket designed to securely mount the fan clutch assembly on select Lexus and Toyota V8 engines.

This fan pulley bracket restores the proper mounting geometry and bearing support for the engine cooling fan. Built to AISIN's factory tolerances, it replaces worn or damaged brackets and their integrated bearings to help maintain reliable fan alignment and reduce stress on the drive belt and fan clutch. Use the vehicle fitment checker to confirm compatibility before purchase.

How does this bracket affect cooling fan performance?

The bracket provides a rigid mounting point and houses a durable bearing that keeps the fan clutch centered and spinning true. A stable bracket prevents wobble and misalignment that can cause premature bearing or clutch wear and increased noise.

• Precision mounting restores original fan alignment and balance
• High-quality bearing reduces lateral play under high RPM
• Die-cast aluminum construction resists distortion from heat and load

What vehicles and engines is the AISIN FBT-002 compatible with?

The FBT-002 fits a range of Lexus and Toyota models produced across late 1990s to 2009 model years. Compatibility may depend on engine type and model sub-variants, so always verify with your VIN or the fitment tool.

• Lexus GX470 (2003–2009), LS400 (1998–2000), LX470 (1998–2007)
• Toyota 4Runner (2003–2009), Land Cruiser (1998–2007), Sequoia (2001–2009), Tundra (2000–2009)
• Confirm engine-specific fitment using the vehicle lookup before ordering

What are the construction and durability features of this AISIN bracket?

Manufactured to match original equipment form, fit, and function, this bracket uses aluminum die-cast technology and tight tolerances to deliver consistent rigidity while minimizing weight. AISIN fits a high-quality bearing inside the assembly to withstand dynamic loads from belt tension and fan resistance.

• Aluminum die-cast body for low weight with high stiffness
• Precision bearings designed for high RPM and repeated thermal cycles
• OE-matched geometry for straightforward installation and long service life

When should I replace the fan pulley bracket?

Replace the bracket if you notice fan wobble, unusual vibration, grinding noise from the fan area, or visible wear on the bearing interface. Because the integrated bearing is a wear item, replacing the bracket during cooling-system service prevents secondary damage to the fan clutch and drive components.

• Signs include noise, vibration, or visible bracket/bearing play
• Recommended during major cooling or front-end mechanical service
• Helps avoid added expense from damaged fan clutch or belts

Who is this for: The AISIN FBT-002 Fan Pulley Bracket is intended for technicians, DIY enthusiasts, and fleet managers maintaining compatible Lexus and Toyota V8 models who need an OE-matched replacement part. It’s suited for anyone replacing a worn bearing or repairing fan-clutch mounting issues and who wants factory-level fit and durability without modification.
