CR Black Differential Housing Upgrade โ Front & Rear (Traxxas 4X4)
(SEE FULL COMPATIBILITY LIST BELOW)
Upgrade your Traxxas 4X4 vehicle with the CR Black Differential Housing from Cobra Racing โ a premium front and rear differential housing upgrade engineered for increased drivetrain strength, improved heat management, and a clean, stealth look. Finished in a deep midnight black coating, this setup delivers serious performance while maintaining a factory-plus appearance on any build.
This complete kit includes both front and rear housings along with a full bearing refresh, making it a true all-in-one differential upgrade rather than a partial replacement.
(Available in multiple colors)
Superior Build Quality
The Cobra Racing Black Differential Housing is CNC-machined from high-quality T6 aluminum, providing a substantial strength upgrade over stock plastic housings. Built to handle high torque loads, aggressive driving, and repeated impacts, these housings significantly reduce flex and long-term drivetrain wear.
Compared to stock housings, this upgrade delivers:
-
Increased rigidity under load
-
Improved gear alignment
-
Greater resistance to deformation
-
Long-term durability for high-power setups
Integrated Heat Management
Excess heat inside the differential accelerates wear and reduces efficiency. These housings feature an integrated heat sink design that helps draw heat away from the differential gears and transfer it into the surrounding chassis.
Benefits include:
-
More consistent performance during extended runs
-
Reduced thermal stress on internal components
-
Improved differential lifespan
Included ABEC-5 Bearing Refresh
This kit includes a full set of ABEC-5 rubber sealed bearings for both the front and rear differentials. Replacing worn bearings during installation helps eliminate slop, reduce friction, and restore smooth drivetrain operation โ an essential step in any serious differential upgrade.
