Fluidampr Steel Internally Balanced Viscous Damper with Adapter Kit – 2022+ Toyota GR86 / Subaru BRZ | FA24F / FA24D | SFI 18.1 | 571111

The Fluidampr 571111 is the purpose-built viscous crankshaft damper for the 2022+ Toyota GR86 and Subaru BRZ — engineered specifically for the FA24 flat-four’s crankshaft configuration and includes the adapter kit required for correct fitment on the FA24 snout. The GR86 and BRZ are the definitive driver’s cars for autocross, time attack, and track day use — and the FA24’s naturally aspirated character means every modification that improves engine efficiency and durability directly translates to more consistent performance at the limit. The Fluidampr controls crankshaft torsional vibration across the entire RPM range, protecting the FA24’s rotating assembly from the harmonic loads that increase with every performance modification, higher rev ceiling, and sustained track session. SFI 18.1 certified — sanctioned for competition use.

Why the FA24 Needs a Fluidampr — and Why the Adapter Kit Matters

The 2022+ GR86 and BRZ moved from the FA20 flat-four to the new FA24 — a larger 2.4L naturally aspirated engine with a revised crankshaft snout configuration. The FA24’s crankshaft snout geometry differs from the FA20, meaning a damper designed for the previous generation does not fit directly. Fluidampr’s 571111 includes a purpose-engineered adapter kit that interfaces the damper correctly with the FA24 crankshaft snout — ensuring accurate concentricity, correct torque transfer, and proper timing mark alignment without requiring any crankshaft modification.

This is not a generic adapter — it is a precision-machined component engineered by Fluidampr specifically for the FA24 application. The adapter kit is what makes the 571111 a direct, reliable installation on the GR86/BRZ FA24 rather than a fitment compromise.

On the engine side: the FA24 is a high-revving naturally aspirated flat-four that GR86 and BRZ owners push hard on track. Every time the engine fires, the crankshaft experiences torsional vibration — a twisting and unwinding motion from the firing pulses. The factory elastomer damper manages this adequately on a stock engine at stock RPM levels, but as you raise the rev ceiling, modify the rotating assembly, or subject the engine to sustained high-RPM track use, the factory damper’s narrow tuning band and rubber degradation become limiting factors. Fluidampr’s viscous silicone fluid damping technology controls torsional vibration across the full RPM range continuously — no tuning band, no rubber to degrade, no loss of effectiveness over time or as the build evolves.

Key Features

• Adapter Kit Included – FA24-Specific Fitment: Includes the precision-machined adapter kit required for correct installation on the FA24 crankshaft snout. The adapter ensures accurate concentricity, correct torque transfer, and proper timing mark alignment — engineered specifically for the FA24, not a generic solution. This is the complete kit; no additional adapter sourcing required
• FA24F (GR86) and FA24D (BRZ) Compatible: The FA24F (Toyota GR86) and FA24D (Subaru BRZ) share the same block and crankshaft architecture with application-specific tuning differences. The 571111 fits both variants — verify your specific application using Fluidampr’s fitment guide before ordering
• Viscous Damping – Full RPM Range Protection: Calibrated silicone fluid viscous damping technology controls crankshaft torsional vibration across the entire RPM range — from idle to the FA24’s 7,500 RPM redline and beyond on modified builds. No narrow tuning band, no degradation over time, consistent protection regardless of how the build evolves
• Internally Balanced: Incorporates internal balance weights replicating the factory damper’s balance contribution to the FA24 rotating assembly — installs as a direct replacement without requiring rotating assembly rebalancing
• SFI 18.1 Certified: Meets SFI Specification 18.1 for harmonic dampers — sanctioned for competition use in SFI-governed racing series including autocross, time attack, and circuit racing. Confirms the damper meets rigorous structural integrity standards for high-RPM competition operation
• Precision CNC Machined Steel: High-grade steel construction, precision CNC machined and balanced — corrosion-resistant black zinc finish with engraved timing marks for accurate ignition timing reference. Maintains dimensional stability under the thermal and mechanical loads of sustained track use
• No Maintenance Required: Sealed viscous fluid chamber requires no servicing over the life of the damper
• Made in USA: Designed and manufactured in the United States. Trusted by leading engine builders and competition teams worldwide

Fitment

• Toyota GR86 — FA24F 2.4L Naturally Aspirated Flat-Four (2022+)
• Subaru BRZ — FA24D 2.4L Naturally Aspirated Flat-Four (2022+)

Includes adapter kit for FA24 crankshaft snout fitment. Verify the 571111 is the correct part number for your specific application using Fluidampr’s fitment guide before purchasing. Not compatible with 2013–2021 FA20-equipped GR86/BRZ — those require a separate Fluidampr part number.

Installation Note: Use a proper harmonic damper installation tool — never drive the damper onto the crankshaft snout with a hammer or impact, as this will damage the crankshaft thrust bearing. Install the adapter kit per Fluidampr’s instructions before fitting the damper. Torque the crankshaft bolt to the manufacturer’s specification — verify whether the FA24 crankshaft bolt is a torque-to-yield fastener requiring replacement at installation. Professional installation recommended.
