Xtrac 383B 6-Speed Sequential Transaxle: Engineered for Uncompromising Performance

Elevate your racing or high-performance build with this
Xtrac 383B 6-Speed Sequential Transaxle – a pinnacle of sequential gearbox engineering designed for the most demanding motorsport applications. Renowned for its precision, durability, and adaptability, the 383B delivers lightning-fast shifts, seamless power delivery, and unmatched reliability under extreme conditions. Whether you're dominating rallycross circuits, conquering hill climbs, or pushing the limits in time attack prototypes, this transaxle is the ultimate drivetrain solution for vehicles requiring sequential efficiency and brute-force torque handling.

Key Specifications and Bulletproof Build
- Gearbox Type: 6-speed sequential with dog-engagement for ultra-quick, positive shifts – no clutch needed for upshifts or downshifts in race mode.
- Torque Capacity: Engineered to handle massive power outputs exceeding 1,000 Nm (738 lb-ft), making it ideal for turbocharged or supercharged setups in GT cars, rally vehicles, or custom track builds.
- Material Excellence: Constructed from high-grade billet steel and advanced alloys for "bulletproof" strength – this isn't just a gearbox; it's an indestructible drivetrain core that shrugs off the harshest abuse.
- Bellhousing: Lightweight magnesium alloy construction reduces rotational mass by up to 40% compared to aluminum alternatives, shaving precious grams while maintaining superior rigidity and heat dissipation.

In pristine as new condition with only *1 hour of dyno test time, this 383B is virtually untouched and ready to bolt in. Plus, it comes with a comprehensive spare parts package, including gears, shafts, synchros, and seals – ensuring minimal downtime and long-term race-ready performance.

Versatile Mounting and Configuration Options
The 383B's modular design offers unparalleled flexibility to suit your project's unique demands:
- Clutch Placement Choices: Opt for the innovative rear-mounted clutch position behind the gearbox for ultra-fast clutch swaps – often achievable in under 10 minutes without disturbing the engine or driveline. This setup minimizes pit-stop times and is perfect for endurance racing or quick-turnaround events. Alternatively, choose the conventional front-mounted clutch against the flywheel on the crankshaft for a straightforward integration with standard engine bays, maintaining compatibility with OEM or aftermarket flywheels.
- Upside-Down Mounting Capability: Yes, the 383B can be inverted ("upside down") for low-slung chassis layouts, such as mid-engine supercars or off-road buggies, optimizing weight distribution and ground clearance without compromising gear ratios or oiling.
- Compact Dimensions Ultra-short bellhousing-to-center CV joint distance (just 180mm standard, customizable to 150mm), enabling tighter packaging in space-constrained vehicles like kit cars, vintage racers, or electric conversion hybrids. This minimizes driveshaft angles and maximizes traction efficiency.

Suggested Applications and Proven Advantages
Tailored for elite-level competition, the Xtrac 383B excels in:
- Rally and Off-Road: Seamless sequential shifts through gravel, mud, or jumps – paired with its robust casing, it's a favorite in WRC-inspired builds.
- Circuit Racing (GT/Prototype): High-torque handling and magnesium bellhousing keep lap times down by reducing unsprung weight and improving thermal management.
- Drift and Time Attack: Quick-reversing sequential action for precise control during slides, with the rear-clutch option enabling rapid maintenance between runs.
- Custom/Street-Legal Builds: Adaptable for road-legal track toys, where the compact footprint and upside-down option fit exotic engine placements.

Advantages at a Glance:
- Speed and Efficiency: Sequential design cuts shift times to under 50ms, boosting acceleration and driver confidence.
- Maintenance Mastery: Rear-clutch config and modular spares mean less wrenching, more winning – cut service intervals by 30% over traditional manuals.
- Weight Savings: Magnesium casing and optimized layout drop overall drivetrain weight by 15-20 kg vs. competitors.
- Durability Edge: Bulletproof materials endure 500+ hours of abuse before major service, with zero reported failures in high-stakes pro series.
