Detailed Product Description
Genuine HKS Motorsport Performance
HKS has built a global reputation for engineering some of the most respected performance components in the automotive industry. Their sequential transmissions are trusted by professional race teams and serious enthusiasts worldwide for their ability to deliver precise shifting performance under extreme conditions.
The HKS Sequential 6-Speed Gearbox – Mazda RX-7 FD3S represents the culmination of decades of motorsport development and drivetrain engineering.
Designed specifically for high-performance applications, this transmission offers significantly improved shift speed and consistency compared to conventional manual gearboxes.
What Makes a Sequential Gearbox Different?
Traditional manual transmissions require drivers to move through an H-pattern gate while simultaneously managing clutch engagement and gear selection.
A sequential gearbox simplifies the process.
Drivers simply push or pull the shifter to move through the gears in sequence.
Benefits include:
- Faster upshifts
- Faster downshifts
- Reduced shift errors
- Improved concentration during racing
- More consistent lap times
- Enhanced vehicle control
For competitive drivers, the reduction in shift time can make a measurable difference in performance.
Built for High-Power Rotary Applications
The Mazda RX-7 FD3S is known for producing impressive power when properly modified, but high-horsepower rotary engines place significant stress on drivetrain components.
This HKS sequential transmission was engineered specifically to handle the demands of powerful rotary setups.
Whether paired with:
- Single turbo conversions
- Twin turbo builds
- Street port engines
- Bridge port engines
- Peripheral port engines
- Competition rotary engines
This gearbox is designed to withstand aggressive driving and repeated high-load operation.
Track and Motorsport Ready
The HKS Sequential 6-Speed Gearbox – Mazda RX-7 FD3S is ideal for drivers who spend serious time on the track.
Applications include:
- Circuit racing
