CR BL Aluminum Front / Rear differential w/ Bearings fits Traxxas Slash Rustler

COBRA RACING Stunning BLUE Aluminum differential.  These differentials can be uséd for either the front or back, as they are exactly the same.  So if you need to replace both differentials on your car, make sure to add 2 in the QTY dropdown.  The differential housing is made of aluminum to enhance aesthetics and durability.  All too often, when doing serious bashing or racing, sometimes the gears inside of the differential strip the entire housing, leaving your car dead in it’s track.  These aluminum differnetials solve this problem because it is much harder to strip aluminum than it is with stock plastic differential housing.

Compatible with:
Traxxas Slash 4×4 / VXL / Platinum / Ultimate
Traxxas Rustler 4×4 / VXL
Traxxas Stampede 4×4 / VXL
Traxxas Hoss 4×4 / VXL
…and most other 1/10 4×4 traxxas RC cars (check manufacturer schematics).

What’s included in the package):
1 CR Blue aluminum differential
2 upgraded Abec5 rubber sealed bearings (for left and right side of the differential)

⚠️ Please Note:  Not compatible with aluminum differential housings without “some” modification.  Perfect / direct fit to stock or other plastic differential housing.  The differential is pre-filled with grease, but for optimal performance and long-term durability, we recommend opening them up and either topping off the grease or replacing it with your preferred differential oil. 

Break-In Period (Highly Recommended):
Once fully installed, it is highly recommended to perform a low-power break-in period. Run the vehicle at half power or on 2S for one to two full battery cycles before stepping up to 3S power. This helps ensure proper seating of internal components and extends the life of the differential.

Important Installation Note:
Depending on your specific setup, proper shimming may be required for correct differential operation. Failing to shim the differential correctly—when needed—can result in excessive wear and potential output gear failure. Always check fitment and adjust as necessary before running.
