51127178280 Rear Bumper: OEM-Specification Protection

Designed with precision contour mapping, the 51127178280 Rear Bumper utilizes impact-modified polypropylene with mineral reinforcement for structural rigidity. The manufacturing process employs Class-A surface tooling that achieves ±0.3mm dimensional accuracy to OEM blueprints, ensuring seamless integration with quarter panels and tailgate interfaces. This primed bumper features uniform wall thickness between 2.8-3.2mm throughout critical impact zones, with reinforced mounting points accommodating factory bracket locations. The smooth substrate surface maintains 98% reflectivity for flawless paint adhesion, while UV-stabilized polymer matrix prevents micro-cracking in temperature extremes from -40°C to 85°C. Strategic ribbing behind impact surfaces provides 15% greater deformation resistance than standard aftermarket units, and the integrated sensor mounting provisions accommodate parking assistance systems without modification. The bumper's clean-surface design omits both license plate recesses and tow hook apertures as specified for select E70 configurations.

Engineering Specifications for 51127178280 Rear Bumper

Material Composition

Manufactured from thermoplastic olefin (TPO) blended with 22% talc reinforcement for impact resistance. The copolymer matrix maintains consistent flexural modulus of 1,600 MPa across environmental conditions. Injection molding utilizes high-pressure packing at 180-bar to eliminate sink marks while achieving surface finish quality of SPI-A2 standard. Internal energy-absorbing structures feature hexagonal crush boxes that distribute impact forces across 35% greater surface area than conventional designs. The primer-ready surface undergoes electrostatic treatment for optimal adhesion, with surface energy measuring 54 dynes/cm² to prevent fisheyes in refinishing processes.

Structural Design

Features BMW-specific mounting geometry with precisely positioned M8 threaded inserts for bumper shock absorption assembly. The bumper core integrates 18 strategic reinforcement ribs that increase torsional rigidity by 28% compared to standard replacements. Sensor mounting provisions accommodate ultrasonic parking sensors with ±0.5mm positional accuracy. Molded-in alignment guides ensure 3mm consistent gap spacing along tailgate interface. The bumper underside incorporates aerodynamic channels reducing drag coefficient by 0.03Cd while preventing road debris accumulation. All fastener locations feature stainless steel reinforcement sleeves preventing thread deformation during installation.

Precise Vehicle Fitment Information

Specifically engineered for 2007-2010 BMW X5 E70 vehicles including 3.0si (2007-2009), 4.8i (2007-2008), xDrive30i (2009-2010), xDrive35d (2009-2010), and xDrive48i (2009-2010) models. Compatible with both standard and M-sport rear valances when equipped with corresponding trim components. This configuration features no integrated license plate recess or tow hook aperture - verify vehicle configuration requirements prior to purchase. Fits vehicles with or without park distance control (PDC) systems, maintaining proper clearance for ultrasonic sensors. Not compatible with models equipped with factory trailer hitch receivers or vehicles manufactured after September 2010 featuring revised bumper mounting architecture.
