SpeedFactory Racing Honda Transmission & Drivetrain Components
Performance Transmission Parts for Honda B-Series & K-Series Engines
SpeedFactory Racing offers specialized transmission and drivetrain components for Honda and Acura racing applications, including front-wheel-drive (FWD) and all-wheel-drive (AWD) builds.
Our product lineup includes billet B-Series transmission bellhousings, AWD transfer cases, billet shift forks, case locks, FWD-to-AWD conversion components, heavy-duty K-Series shift selectors, and related transmission hardware.
These components support builders developing high-performance Honda transmissions for drag racing, competitive motorsports, and custom drivetrain applications.
SpeedFactory Racing B-Series Billet Bellhousings
SpeedFactory Racing offers billet transmission bellhousings for B-Series FWD and AWD applications.
The FWD B-Series Billet Bellhousing and AWD B-Series Billet Bellhousing are separate products designed for their respective transmission configurations.
Billet bellhousings are commonly considered for demanding racing builds where transmission case construction, component alignment, and compatibility with upgraded drivetrain components are important.
Before selecting a bellhousing, verify the engine platform, transmission configuration, internal components, and installation requirements.
FWD and AWD bellhousings should not be assumed interchangeable.
B-Series AWD Billet Transfer Cases & Case Locks
SpeedFactory Racing offers specialized components for Honda B-Series AWD transmission systems.
AWD B-Series Billet Transfer Case
The SpeedFactory Racing AWD B-Series Billet Transfer Case is an option for builders assembling performance-oriented AWD drivetrains.
The transfer case is an important component of the AWD power delivery system, transferring power through the appropriate drivetrain arrangement.
B-Series AWD Case Lock
The SpeedFactory Racing B-Series AWD Case Lock is designed to address a specific area of concern with B-Series AWD outer transmission cases.
For high-performance AWD builds, correct case assembly, internal component compatibility, and drivetrain alignment are important considerations.
SpeedFactory Racing Billet Transmission Shift Forks
SpeedFactory Racing offers billet shift forks for selected Honda B-Series transmission applications.
Available components include FWD B-Series Billet Shift Forks and an AWD B-Series 1-2 Billet Shift Fork.
Shift forks are responsible for moving transmission engagement components during gear selection.
In racing applications, shifting loads, transmission design, and the condition of internal components can affect reliability and shift performance.
When selecting replacement or upgraded shift forks, verify transmission type, gear arrangement, and compatibility with the shift mechanism.
Honda B-Series FWD-to-AWD Transmission Conversion Components
SpeedFactory Racing offers a Billet FWD2AWD B-Series Gear Conversion Kit and additional components used in custom B-Series AWD transmission builds.
Converting a Honda drivetrain from FWD to AWD involves more than replacing a single transmission component.
Builders must account for transmission case compatibility, internal gearing, transfer case configuration, differential selection, driveshaft arrangements, axle fitment, and chassis-specific installation requirements.
SpeedFactory also offers specialized AWD transmission components such as an offset reverse shaft and an input shaft speed sensor mounting tab for selected configurations.
Because Honda AWD transmission components vary by application and model year, verify compatibility before purchasing conversion parts.
Heavy-Duty Honda K-Series Shift Selectors
SpeedFactory Racing offers a Heavy Duty K-Series Shift Selector for compatible Honda K-Series transmissions.
The shift selector is part of the mechanism that translates gear-selection inputs into the movement required to engage transmission gears.
For performance applications, shift selector condition and compatibility are important considerations when assembling or upgrading a transmission.
The appropriate solution depends on the transmission version and the rest of the shifting system.
Modified B-Series Shift Change Holder Assemblies
SpeedFactory Racing offers a Modified Shift Change Holder Assembly for selected B-Series FWD hydraulic transmissions.
This component is intended for specialized performance transmission applications, including compatible factory-style and dog-engagement transmission configurations.
Transmission builders should verify the required shift mechanism arrangement, transmission generation, and associated internal components before installation.
Choosing the Right Honda Racing Transmission Components
When selecting performance transmission parts for a Honda or Acura build, consider the complete drivetrain configuration.
Important factors include:
- B-Series or K-Series engine and transmission platform
- FWD versus AWD drivetrain configuration
- Transmission case and bellhousing compatibility
- Factory-style synchronized versus dog-engagement gear arrangements
- Shift fork and shift selector requirements
- Transfer case, differential, and final-drive compatibility
- Intended racing application and drivetrain load
- Professional assembly and installation requirements
High-performance transmission reliability depends on correct component selection, assembly procedures, lubrication, drivetrain alignment, and operating conditions.
Upgrading one component does not eliminate the need to inspect and properly assemble the entire transmission.
Frequently Asked Questions About Honda Performance Transmissions
What is the difference between a FWD and AWD B-Series transmission?
A FWD transmission drives the front wheels, while an AWD drivetrain uses additional components to distribute power to both axles. Honda B-Series AWD applications require compatible transmission cases, transfer case arrangements, gearing, and supporting drivetrain components.
Why use a billet B-Series transmission bellhousing?
Billet bellhousings are used in specialized performance transmission builds where builders require a particular housing design and compatibility with upgraded drivetrain assemblies. The correct housing depends on whether the transmission is configured for FWD or AWD operation.
What does a billet shift fork do?
A shift fork moves the appropriate transmission engagement components during gear selection. Billet shift forks are an aftermarket upgrade option for supported racing transmission configurations.
Can a Honda B-Series FWD transmission be converted to AWD?
Certain B-Series configurations can be adapted for custom AWD builds using compatible transmission components. The conversion requires careful planning and may involve significant mechanical modifications. Compatibility is not universal.
Are all Honda B-Series AWD transmission cases interchangeable?
No. Transmission cases and internal arrangements can differ between applications and model years. Verify the exact transmission components and fitment requirements before assembling a custom AWD system.
Does SpeedFactory Racing offer K-Series transmission upgrades?
Yes. SpeedFactory offers a Heavy Duty K-Series Shift Selector for supported applications. Review the individual product specifications to confirm compatibility with your transmission.
