Fitment Notes

• This is a crankshaft adapter hub kit only - NOT a complete harmonic damper. It must be used with Fluidampr FA20 damper, part number 571101 (sold separately)
• Designed for use on Subaru FA24, FB20, and FB25 engine platforms only - allows the FA20-spec Fluidampr damper to bolt onto these crankshafts
• Includes OEM-spec crankshaft bolt (Subaru p/n 12369AA091) - required for correct torque retention
• Professional installation recommended; crankshaft bolt must be torqued to Subaru factory specification

Features

• Precision-engineered 4340 steel adapter hub bridges the crankshaft interface difference between FA20 and FA24/FB20/FB25 engines, allowing the same high-performance Fluidampr damper to serve across multiple Subaru platforms
• O-ring seals the adapter hub to the crankshaft for a secure, leak-free fit without silicone sealant or additional sealing materials
• Includes the OEM Subaru crankshaft bolt (p/n 12369AA091) for correct torque specification compliance and thread engagement
• Rust-inhibitor coated finish provides corrosion resistance in the engine bay environment
• Enables full access to Fluidampr's self-tuning viscous damper technology for FA24/FB20/FB25 engines, which is not available in a direct-fit standalone unit
• Made in the USA by Vibratech TVD

Product Description

The Fluidampr 300023 is a crankshaft adapter hub kit that enables the Fluidampr FA20 damper (p/n 571101) to be installed on Subaru FA24, FB20, and FB25 engine platforms - covering applications from the 2017+ Impreza and 2018+ Crosstrek to the 2022+ WRX, BRZ, and Toyota GR86. The FA24/FB20/FB25 crankshaft uses a different hub interface than the earlier FA20 engine, so this adapter kit bridges that gap, allowing owners of these newer-generation Subaru and Toyota flat-four platforms to take advantage of Fluidampr's proven viscous damper technology without purchasing an entirely new damper assembly.

The kit includes a precision 4340 steel adapter hub, an O-ring for a secure crankshaft seal, and the OEM Subaru crankshaft bolt for correct torque retention. This is an accessory component kit - the Fluidampr FA20 damper (571101) must be purchased separately. Both the 300023 adapter kit and the 571101 damper are also conveniently sold together as a complete package under Fluidampr part number 571111. Made in the USA by Vibratech TVD.
