Traxxas Differential Assembly Bevel Gear Front Or Rear / Pinion Gear TRX10780X

This kit comes Pre-Assembled from the factory, saving you the complex and greasy task of shimming and aligning internal spider gears. It is a "drop-in" solution to get your vehicle back on the water or dirt in minutes.

1. Hardened Steel Bevel & Pinion Gears

• Wear Resistance: The ring and pinion gears are manufactured from high-carbon hardened steel. This prevents the "teeth stripping" common in high-voltage 6S brushless setups during aggressive acceleration.

• Precision Mesh: These gears are CNC-machined for a perfect mesh, reducing heat buildup and mechanical whine while increasing overall drivetrain efficiency.

2. Complete Sealed Differential Carrier

• Spider Gear Integration: The internal small bevel gears (spider gears) are already installed and sealed within the housing.

• Tunable Performance: The differential is designed to be filled with silicone differential oil (sold separately), allowing you to tune the "limited-slip" action for better cornering or straight-line stability.

3. Universal Front/Rear Fitment

• Symmetrical Design: This assembly is identical for both the front and rear gearboxes of the Spartan SR, making it an essential spare part to keep in your toolbox for race days.

• Direct Bolt-On: Features factory-spec mounting points for the drive cups and ring gear, ensuring a wobble-free fit into the bulkhead.
