advantages

Tough Enough for Heavy-Duty Use：We go with SAE 4140 alloy steel, forge it under high pressure, then temper it fully to boost strength and toughness. This setup lets the differential handle heavy drivetrain torque reliably, no warping or cracking even in long-haul conditions.

Smooth Power Transfer & Less Wear：Our CNC-machined gear teeth have an optimized profile for tight meshing. Every tooth lines up perfectly, cutting down friction and noise-so the assembly runs smoother and lasts longer than generic alternatives.

Keeps Contaminants Out for Longer Life：We use double-lip silicone seals with a built-in spring. They snug tight against the housing, blocking dust, mud and water from getting in while locking in lubricant. This keeps internal parts protected, extending service intervals nicely.

Stays Cool Under Pressure：The integrated heat dissipation fins add extra surface area. When hauling heavy loads or climbing hills, they draw away heat faster, preventing overheating and keeping gear and bearing performance steady.

Compatible Models

Fits Sinotruk Howo T-series (including T7H, T5G, T6G) trucks. Also works with Shaanxi Auto Shacman X3000, M3000, and similar heavy-duty truck models equipped with matching middle axle configurations.

FAQ

Q: Is the bearing pre-set, or is that a job for the shop?
A: Good question. It comes ready to go. We set the bearing preload at the factory so you get a quiet, smooth-running unit right out of the box. This saves you time on the install and helps prevent early bearing failure.

Q: What about sealing? I don't want leak issues down the road.
A: Totally get it. Leaks are a headache. This assembly uses a dual-lipped seal made from FKM material, which is a lot tougher than standard rubber against heat and oil. It does a solid job keeping the gear oil in and road contaminants out.

Q: Will it be a direct fit, or am I looking at modifications?
A: It's a direct replacement. We machine the housing to OEM specs, so the 199014320165 Middle Axle Differential Assembly should bolt right into place without any fuss. Just make sure your model is on the compatibility list.
