Genuine HOHAN AZ1651210002 left-side door assembly for SINOTRUK HOWO J7B cabins. Complete unit with frame, glass, mirror, and wiring.
A cracked window, broken latch, or sagging hinge might seem minor — until your driver gets stuck in heavy rain with a jammed door. That’s why the HOHAN AZ1651210002 J7B left door assembly matters: it’s not just sheet metal, it’s a complete safety and comfort system built for the harsh realities of long-haul transport.
Designed as a direct replacement for SINOTRUK HOWO T7H, A7, and ZZ1257 series trucks, this original-spec left door comes fully assembled with tempered glass, integrated side mirror, pre-wired harness, internal reinforcement beams, and factory-matched paint code (typically RAL 9007 or custom per batch). The outer skin is cold-rolled steel with anti-corrosion coating — essential for coastal ports or salt-heavy winter roads in Central Asia.
Inside, the door features sound-dampening foam layering to reduce cabin noise, plus sealed channels that keep dust and moisture out, even after years of off-road use. All hardware — handles, locks, window regulators — meets HOHAN’s OEM durability standards, so you’re not replacing it again in six months like cheap third-party copies.
Whether you’re repairing a collision-damaged cab in Nigeria, upgrading an aging fleet in Chile, or supplying a mining operator in Mongolia, choosing the genuine AZ1651210002 means faster fitment, better resale value, and fewer service callbacks.

Replacing a cabin door on a SINOTRUK HOWO isn’t just about bolts and hinges — it’s about alignment, safety, and electrical function. Before installing the AZ1651210002 J7B left door, support it with a helper or lift arm — these doors weigh over 35 kg and can damage the hinge or injure hands if dropped. Remove the three main hinge bolts using a 14mm socket; clean rust from mounting points if needed. Align new door carefully — start with top hinge, then secure bottom. Adjust gap uniformly around windshield and fender (ideal clearance: 4–6 mm). Reconnect side mirror wiring harness and check power window operation before final tightening. Test door latch at multiple positions to ensure smooth closure. Lubricate rubber seal and striker plate annually in dusty or coastal environments to prevent wear.
