17118572189 Bracket | Structural Radiator Support for BMW X5/X6 (2013-2019)
17118572189 Bracket: Precision Engineered Radiator Support Mount for BMW X5/X6
Manufactured to exact specifications, the 17118572189 and 17118572188 radiator support brackets deliver critical structural reinforcement for BMW X5 F15 and X6 F16 chassis. This high-tolerance 17118572189 Bracket system provides secure mounting for radiator assemblies while maintaining precise suspension geometry alignment. The bracket's laser-cut design replicates original load distribution patterns with reinforced stress points at vibration-prone junctions. Manufactured from cold-rolled SAE 1008 steel with electro-coating protection, the component withstands road debris impacts and corrosion from de-icing chemicals. During installation, the precision-drilled mounting holes align effortlessly with factory chassis points, eliminating need for modification or force-fitting. The 17118572189 Bracket maintains critical bumper-to-radiator clearances specified for aerodynamic efficiency while providing thermal expansion accommodation through slotted mounting points.
Each bracket undergoes dimensional validation using coordinate measuring machines to ensure micrometer-level accuracy across all mounting surfaces. The zinc-nickel plating creates a sacrificial barrier that outperforms conventional electroplating in salt spray tests while maintaining electrical continuity for grounding systems. Unlike universal alternatives, this solution preserves the engineered crumple zones that contribute to the vehicle's safety ratings. The symmetrical design balances radiator weight distribution across both frame rails, preventing uneven stress on cooling system components. Owners will appreciate how this 17118572189 Bracket restoration maintains original suspension kinematics while providing enhanced resistance against fatigue cracks at high-mileage intervals. The component's powder-coated finish matches factory textures while its optimized mass distribution avoids adding unnecessary weight to the front suspension assembly.
Vehicle Application Precision
This radiator support mounting solution features application-specific engineering calibrated exclusively for second-generation BMW SAV platforms. Direct replacement compatibility covers all F15 X5 variants manufactured between 2013-2018 model years, including 30i, 35i, 40i, and 50i powertrain configurations regardless of suspension package. The 17118572189 and 17118572188 components maintain identical fitment specifications for F16 X6 models across the same production period, accounting for subtle differences in hybrid and M performance variants. Mounting points align perfectly with factory chassis brackets while clearance allowances accommodate both standard and auxiliary radiator configurations.
These brackets accommodate all factory cooling system variations including N55, N63, and S63 engine installations. Critical dimensional parameters maintain original equipment specifications for vehicles equipped with active air flap systems or headlight washers. The 17118572189 Bracket system functions seamlessly with both steel and aluminum hood latch mechanisms while providing proper sensor mounting locations for pedestrian protection systems. When installed according to manufacturer instructions, these components preserve the engineered deformation characteristics required for crash safety compliance without interfering with tow hook access or skid plate installations.
Engineering Specifications
Material Technology
Base material utilizes cold-rolled SAE 1008/1010 steel with 250 MPa minimum yield strength, precision-stamped using 800-ton progressive dies for consistent dimensional replication. Surface treatment employs ternary zinc-nickel alloy electroplating achieving >720 hours neutral salt spray resistance, exceeding conventional zinc coatings. The 17118572189 Bracket features hex flange bolts manufactured from ISO 898 Class 8.8 steel with mechanical galvanizing that maintains clamp load integrity under thermal cycling conditions.
Structural Design
Computer-optimized rib patterns increase section modulus by 40% compared to flat-stock alternatives while minimizing added mass. Embossed reinforcement channels redirect impact forces away from radiator end tanks during low-speed collisions. The 17118572189 Bracket design incorporates harmonic dampening through tuned thickness variations that disrupt resonant frequencies between 80-120Hz where engine vibrations peak.
Precision Manufacturing
Laser-cut mounting holes maintain positional accuracy within ±0.15mm tolerance across production batches. Robotic welding creates consistent penetration depth at all critical joints while preventing heat distortion in thin-gauge areas. The 17118572189 Bracket undergoes coordinate measuring machine validation against digital master models with 25-point inspection protocols ensuring perfect fitment with adjacent hood latch panels and front reinforcement beams.
Compatible with: BMW X5 F15 (2013-2018), BMW X6 F16 (2014-2019) with 30i, 35i, 40i engines. Replaces original components 17118572189 and 17118572188. Not affiliated with or endorsed by BMW AG.
