Losi LOS232075 HD Diff Housing & Internals — HR, RR, BR

The Losi® LOS232075 HD Diff Housing & Internals is a heavy-duty differential housing and internal components set for the HR (front), RR (rear), and BR positions on compatible Losi vehicles. The HD designation indicates reinforced, heavy-duty construction designed to handle higher torque loads and more demanding driving conditions than standard diff components — making this an ideal upgrade for high-power builds, aggressive bashing, and racing applications where stock diff housings and internals are prone to wear or failure. Installing HD diff components improves drivetrain durability and helps maintain consistent differential performance under sustained high-load operation.
