JDM Subaru Legacy Spec B 6-Speed Manual Transmission TY856WBDAA (Non-DCCD) w/ R180 Diff, Axles, Subframes, Brakes & Hubs

For sale is a complete JDM Subaru Legacy Spec B performance drivetrain package, featuring the highly sought-after TY856WBDAA 6-speed manual transmission (non-DCCD) along with a matching R180 rear limited-slip differential, axles, front and rear subframes, brakes, and wheel hubs. This is an exceptional OEM Spec B swap package, ideal for Subaru enthusiasts looking for strength, reliability, and factory-engineered performance.

The TY856WBDAA 6MT is part of Subaru’s legendary STI-based transmission family and is widely regarded as one of the strongest manual gearboxes Subaru ever produced. Unlike standard 5-speed transmissions, the Spec B 6-speed offers significantly improved torque handling, durability, and smoother power delivery, making it an excellent choice for high-performance street cars, track builds, and long-term reliability upgrades. Being non-DCCD, this transmission is simpler to install while retaining the core strength of the STI-derived drivetrain.

Paired with the R180 rear LSD, this setup provides improved traction, durability, and balanced torque distribution compared to smaller R160 differentials. The inclusion of matching axles, hubs, brakes, and subframes makes this a true turn-key drivetrain solution, greatly reducing compatibility issues and saving time and money during installation.

This package is ideal for:

• Subaru drivetrain swaps

• Legacy, Impreza, WRX, or project builds (with proper compatibility checks)

• Performance and motorsport applications
