Dongfeng Xinjiang X7 truck white Right front bumper 8406022-TXGG01Y

Built to withstand minor collisions (e.g., hitting curbs, small rocks) and road debris impacts common in Xinjiang’s mining or desert transport, the bumper is crafted from a high-performance PP+TPO composite (70% polypropylene, 30% thermoplastic olefin). This material delivers a notched Izod impact strength of 12 kJ/m² at -30°C (resisting cracking in frigid winters) and a flexural modulus of 1,800 MPa—stiff enough to maintain shape under pressure yet flexible enough to absorb impact energy (up to 80J) without permanent deformation. The composite undergoes injection molding at 220°C with a 3mm-thick wall structure (reinforced to 5mm at stress points like corners), ensuring it can withstand 50+ low-speed impacts (≤5km/h) without cracking. Compared to traditional steel bumpers, this lightweight composite design reduces front-end weight by 35% (from 12kg to 7.8kg) while maintaining comparable impact resistance—critical for improving fuel efficiency in long-haul operations

Finished with a factory-matched white automotive-grade paint (RAL 9003 pure white), the bumper features a three-layer coating system that ensures color consistency and long-term resistance to fading:

Epoxy Primer (50μm): Provides adhesion to the composite surface and prevents chemical corrosion.

Polyester Basecoat (80μm): Delivers the signature white color, matched to the X7’s cab paint via spectrophotometer testing (ΔE ≤1.5, meeting automotive color tolerance standards).

Acrylic Clearcoat (40μm): Adds scratch resistance (Mohs hardness ≥3H) and UV protection, passing 3,000 hours of xenon lamp aging testing with ≤2% color fade—critical for enduring Xinjiang’s 3,000+ annual hours of intense sunlight.

The coating is also hydrophobic (water contact angle ≥90°), repelling rainwater and mud to reduce cleaning frequency—ideal for trucks operating in dusty mining or agricultural areas

Engineered to retain the X7’s original front-end functionality, the bumper includes pre-machined cutouts and mounting points for key components:

Fog Light Cutout: A 160mm-diameter precision cutout (tolerance ±0.5mm) that fits the X7’s factory right front fog light (e.g., part No. 3732120-C33X701SY), with built-in plastic brackets for secure installation—no additional drilling required.

Tow Hook Mount: A reinforced 12mm-thick steel insert (embedded in the composite during molding) with a M20 threaded hole, capable of withstanding a maximum tow load of 8,000kg—matching the X7’s factory tow capacity.

Lower Air Dam: A integrated 50mm-tall air dam along the bumper’s bottom edge that directs airflow to the radiator, improving cooling efficiency by 8% compared to bumpers without this feature—critical for maintaining engine temperature in hot desert conditions

Designed for easy installation by fleet technicians or repair shops, the bumper simplifies replacement with user-friendly features:

Mounting Hardware: The package includes 6 grade 8.8 high-strength M12×40mm bolts (for frame attachment) and 4 M6×16mm screws (for fog light brackets), all pre-coated with anti-corrosion zinc plating to resist rust in snowy or humid conditions.

Alignment Aids: Laser-etched reference lines on the bumper’s backside align with the X7’s front frame marks, eliminating the need for time-consuming measurement—ensuring correct positioning in 10 minutes.

Lightweight Design: Weighing only 7.8kg, the bumper can be installed by one technician without lifting equipment, reducing labor time by 50% compared to heavy steel bumpers.

Installation takes 45–60 minutes total: remove the old bumper by detaching frame bolts and fog light connections, align the new bumper’s reference lines, secure with bolts (torqued to 80 N·m for M12, 25 N·m for M6), and reconnect the fog light. Each unit undergoes dimensional inspection via CMM, impact testing, and paint adhesion checks, backed by a 24-month warranty against defects (e.g., cracking, paint peeling, mounting point failure)
