Internal Differential Gear Set
This kit contains the small planetary spider gears that reside inside the rear differential. These are the primary failure point, typically stripping teeth under the high-torque loads of the VXL-6S motor when landing jumps while on throttle.

Differential Housing/Carrier (Rear)
The differential carrier housing often experiences internal scoring or thermal warping when the planetary gears fail. If the housing is not replaced with the gears, the new gears may not mesh correctly, leading to a repeat failure within a few hours of operation.

20,000,000 wt Silicone Differential Oil
Ultra-thick silicone fluid is critical for the UDR's rear planetary assembly to provide the necessary resistance and lubrication. It prevents 'unloading' of power to a single wheel, which is the leading cause of centrifugal gear explosions in the rear axle.
