Designed for SINOTRUK Sitrak C7H, C5H, and Zo series trucks, the OEM 810W90685-0395 wheel nut plastic trim combines lightweight durability with aggressive styling. This trim cover perfectly snaps onto the wheel nut assembly, providing a sleek, uniform finish while preventing moisture and salt from attacking the underlying metal hardware. As an essential 810W90685-0395 component, it maintains the integrity of your wheel fastening system under extreme road conditions. The high-grade ABS + engineering plastic material resists UV radiation, cracking, and fading, keeping your Sitrak looking professional even after hundreds of thousands of kilometers.
Each 810W90685-0395 unit is manufactured under strict Sinotruk quality control, ensuring dimensional accuracy and perfect retention force. Whether you are a fleet manager looking to refurbish a dozen trucks or an owner-operator seeking a single replacement, this genuine trim guarantees hassle-free installation. No special tools required — simply press firmly until it clicks into place. The plastic trim also reduces rotational noise and covers sharp edges, adding an extra layer of safety during wheel maintenance.
The plastic trim creates a sealed barrier against road salts, calcium chloride, and mud, preserving lug nut threads and preventing seizing.
Engineered specifically for SINOTRUK Sitrak Zo & C-series hubs. OEM 810W90685-0395 ensures zero wobble and perfect engagement with wheel nut geometry.
Withstands extreme temperatures from -40°C to +120°C. High-impact copolymer resists cracking from stone chips or accidental hammer strikes.
Enhances the modern look of your Sitrak truck. Uniform plastic trim covers worn nuts, giving wheels a fresh, consistent appearance for brand image.
The 810W90685-0395 Wheel Nut Plastic Trim is cross-compatible with multiple Sinotruk Sitrak chassis configurations, including Zo series long-haul tractors, C7H heavy-duty dumpers, and C5H construction trucks. Replacing old, faded or missing trims with this OEM-grade part restores the original factory finish. This component is also suitable for certain HOWO T7H models that share the same wheel nut interface (please verify your existing part number). The trim’s internal ribs and locking tabs provide secure retention even on rough terrain, so you never lose a cover during transit.
Made from UV-stabilized black plastic, the 810W90685-0395 does not discolor or become brittle under intense sunlight. Its smooth surface allows easy cleaning with just a pressure washer or a damp cloth, keeping your rims and nuts free from grime buildup. Because it is lightweight (only 48 grams), it does not affect wheel balance or rotational mass — a critical advantage for fleets monitoring fuel efficiency and tire wear uniformity.

Fleet owners and owner-operators recognize that small details like wheel nut covers contribute to overall resale value and professionalism. The 810W90685-0395 trim is built to last through harsh winters, desert heat, and constant vibration. Unlike cheap universal caps that fall off after the first pothole, the genuine Sinotruk part features a double-locking ring design with reinforced retention clips, tested for over 200,000 km of mixed on/off-road use.
Maintenance is simple: during each tire rotation or brake inspection, remove each 810W90685-0395 trim carefully, clean any debris from the wheel nut cavity, and reattach until you hear a distinct “click”. This prevents moisture entrapment which could otherwise cause galvanic corrosion between steel nuts and alloy wheels. For logistics companies operating SINOTRUK Sitrak fleets, stocking the OEM 810W90685-0395 as a standard consumable ensures every truck maintains identical visual branding — a subtle but powerful marketing asset.
The plastic trim also acts as a visual indicator: if a trim becomes loose or missing, it may indicate that the underlying wheel nut requires tightening. This simple safety cue helps drivers or maintenance crews quickly identify potential issues during walk-around inspections. Investing in genuine 810W90685-0395 components reduces downtime related to seized or damaged wheel nuts, because the trim effectively repels water and salt spray from entering the thread area. With more than 85% of heavy truck wheel nut failures linked to corrosion, using a high-quality plastic cover is a low-cost, high-impact preventive measure.
Additionally, the aerodynamic shape of the 810W90685-0395 reduces minor drag around the wheel hub area — an incremental improvement that contributes to overall fuel savings when multiplied across an entire fleet. Sinotruk engineers optimized the profile to seamlessly integrate with the Sitrak wheel design, maintaining the vehicle’s original coefficient of drag while adding functional protection.
When it comes to maintaining your SINOTRUK Sitrak, using authentic parts ensures maximum reliability and safety. The 810W90685-0395 Wheel Nut (Plastic Trim) Sitrak Zo is manufactured to the same standards as the original factory components. Upgrade your truck’s wheel appearance, protect critical hardware, and extend the life of your wheel fastening system with this simple yet robust accessory. Whether you are performing a full restoration or just replacing lost trims, the 810W90685-0395 part gives you peace of mind on every journey. Choose durability, choose precision fit, and keep your Sitrak rolling with the unmatched quality of Sinotruk genuine parts.
