FULLY UPGRADED DODGE VIPER T56 6-SPEED MANUAL TRANSMISSION – REBUILT & REINFORCED
Hook: Build the ultimate high-horsepower manual swap, or give your Viper a bulletproof, crisp-shifting gearbox! The Dodge Viper-spec T56 is globally legendary as the absolute holy grail of 6-speed manual transmissions, featuring a massive 30-spline output shaft and a highly robust gearset designed to handle brutal torque.
Sourcing any Viper drivetrain component in Europe is an absolute nightmare. Finding a low-mileage, professionally built and upgraded unit already prepared for heavy-duty street or track abuse is practically impossible. This complete high-performance transmission is ready to ship immediately!
——————————
Premium Upgrades & Reinforcements:
This unit started as an exceptionally low-mileage factory Viper T56 and was completely torn down, inspected, and rebuilt with premium performance components:
• Upgraded Synchros: Equipped with high-friction carbon/bronze synchro rings to ensure buttery-smooth, grind-free shifts even at high RPMs.
• Heavy-Duty Shift Forks: Upgraded with high-strength billet steel shift forks to replace the weak factory aluminum pieces, preventing bending during aggressive gear slams.
• Upgraded Sliders & Billet Keys: Replaced stock plastic keys with heavy-duty billet keys and upgraded spring packs to guarantee positive gear engagement and prevent pops-outs.
• New Seals & Bearings: 100% refreshed throughout with premium seals and high-load capacity bearings.
——————————
The Highlights:
• Flawless Mechanical Condition – Only test-run for minimal mileage since the comprehensive rebuild. Operates flawlessly with incredibly tight, quick, and precise throws.
• Extreme Torque Capacity – Built to easily handle 700+ horsepower and brutal V10 or built V8 torque curves.
• Viper & Restomod Swap Ready – The ultimate, heavy-duty manual transmission choice for Dodge Vipers, high-end LS/LT swaps, or custom classic muscle car builds.
•Premium Transit Container – Avoid shipping damage! This high-value transmission ships bolted securely inside a proper, heavy-duty, impact-resistant sealed hard-plastic shipping container to guarantee it arrives at your shop in pristine condition.
