Protect your truck’s cab and improve its aerodynamics with the genuine FAW Upper Front Left Wheel Fender, OEM part number 5103161-B90/D. This crucial body panel is mounted above the front left wheel, serving as a primary shield against road spray, mud, stones, and debris thrown up by the tire. As a vital protective component among durable Faw truck parts, the 5103161-B90/D fender helps keep the cab side, door, and fuel tank area cleaner and less prone to corrosion.
Its contoured design also contributes to managing airflow around the front of the vehicle. Replacing a damaged or rusted fender with the authentic 5103161-B90/D unit restores your FAW truck’s structural integrity, aesthetic lines, and provides essential protection for both the vehicle and other road users. It is a direct-fit, left-side specific replacement part.

The 5103161-B90/D fender’s primary role is to act as a mudguard and stone deflector for the front left wheel. It dramatically reduces the amount of water, slush, mud, and gravel projected onto the cab door, steps, and lower chassis components.
This protection is crucial for preventing accelerated corrosion and keeping the vehicle cleaner. Aerodynamically, its shape helps guide turbulent air from the rotating wheel away from the truck’s side, reducing drag and improving stability, especially at highway speeds.
This fender is typically fabricated from stamped, galvanized steel or high-impact composite plastic. Steel offers superior strength and resistance to impact from kicked-up debris. Galvanization provides a foundational layer of rust protection.
Composite plastic fenders are lighter, impervious to rust, and can flex slightly upon impact. The part is primed and ready for painting to match the truck’s cab color. Mounting flanges are reinforced for secure attachment to the cab structure and chassis brackets.
| Parameter | Specification |
|---|---|
| OEM Part Number | 5103161-B90/D |
| Component Type | Upper Front Left Fender / Mudguard |
| Compatible Brand | FAW Truck Models (Left Side) |
| Primary Material | Stamped Steel or Composite Plastic |
| Finish | Primed for Paint (OEM Color-Match) |
| Mounting | Bolts to Cab Mounts & Chassis Brackets |
Installation requires removing the old fender, which involves detaching numerous bolts around its perimeter and from supporting brackets. Care must be taken with any wiring or air lines routed behind it.
The new 5103161-B90/D fender is carefully positioned. It’s crucial to start all mounting bolts by hand to ensure perfect alignment with the cab door, roofline, and lower fender extension. Final tightening follows a sequence to avoid distortion and ensure even gaps.
Severe rust perforation, especially along welded seams or mounting flanges, compromises the panel’s strength. Large dents or creases from impacts distort its shape, reducing effectiveness and aesthetics.
Cracks in plastic fenders or extensive paint damage that exposes bare metal to the elements are clear indicators. A loose or misaligned fender that rattles or has uneven gaps also requires attention to prevent further damage.
The fender directly protects the lower cab corner and door from stone chips and corrosion. This area is highly vulnerable to rust if paint is constantly chipped away by debris. Protecting it preserves cab integrity.
It also shields electrical connections, air brake lines, and fuel tank fittings often located in this area from direct bombardment by road materials, preventing leaks, shorts, and other failures.
By containing wheel spray, the 5103161-B90/D fender improves visibility for following vehicles and keeps the truck’s own steps and handholds cleaner and safer to use. This is a considerate safety feature for shared roads.
It significantly reduces the amount of abrasive dirt and salt that accumulates on the chassis in this area, slowing down corrosion and reducing the frequency of required undercarriage cleaning.
The 5103161-B90/D is specifically for the LEFT front upper position. The right-side fender is a different part number with a mirror-image contour. Fitment is also precise to the FAW truck model, cab length, and wheelbase.
A fender for a different model or side will not align with mounting points or match the curvature of the cab and fuel tank. Always confirm you are ordering the left-side part and verify compatibility with your VIN for a perfect fit.
This fender is a major visual element that flows from the front bumper into the cab side. A clean, straight fender contributes significantly to the truck’s streamlined, professional appearance.
Damage or rust in this panel is highly noticeable and detracts from the vehicle’s overall image. Replacing it with a new 5103161-B90/D restores the cohesive, powerful look that is important for both pride of ownership and commercial branding.
Regularly wash the fender, especially the inner surface, to remove accumulated mud and road salt that trap moisture. Inspect for stone chips in the paint and touch them up immediately to prevent rust start.
Check the tightness of mounting bolts during routine service, as vibration can loosen them. For steel fenders, applying a rust-inhibiting undercoating to the inside can significantly extend its lifespan in harsh climates.
Steel fenders offer traditional strength and are often original equipment. They can be repaired (dent removal) more easily but are susceptible to rust if not properly maintained. They provide a solid, OEM feel.
Composite plastic fenders are a modern alternative. They are rust-proof, lighter, and can often flex back after minor impacts. They may be more resistant to chipping but can be harder to repair if cracked.
A genuine 5103161-B90/D fender guarantees perfect dimensional accuracy. It will align with every factory mounting hole and match the exact contour of your specific cab model, ensuring proper fit and protection.
Aftermarket fenders may have subtle differences in shape or flange design, leading to installation difficulties, poor gaps, or reduced effectiveness in deflecting spray. The genuine part ensures restoration to original specifications.
A truck with solid, rust-free fenders is far more valuable and appealing to buyers. Rust in this area often indicates broader corrosion issues. A new fender addresses a major visual and structural concern.
From a safety standpoint, a secure fender prevents loose parts on the highway. It also ensures optimal aerodynamic performance, which can affect high-speed stability and fuel efficiency—factors in overall operating cost and safety.
The upper fender works in conjunction with inner fender liners (splash shields) and lower fender extensions. The 5103161-B90/D is designed to create a seamless or overlapping joint with these other components.
This integrated system provides comprehensive protection. When replacing the upper fender, it is wise to inspect and potentially renew these related parts to ensure the entire protective assembly is intact.
In summary, the FAW Upper Front Left Wheel Fender 5103161-B90/D is a vital component that combines practical protection with important styling. It guards against corrosion, improves aerodynamics, and defines the vehicle’s side profile.
Its durable construction is built for the punishing environment near the wheels. Choosing the genuine, side-specific part and installing it correctly ensures long-term performance and preserves the truck’s value.
This investment protects your cab, enhances safety for others, and maintains the professional, rugged appearance expected of a FAW truck. It is a fundamental part of responsible vehicle maintenance and presentation.
