51717228081 Crossmember: Structural Reinforcement for BMW Front-End Systems
Precision-engineered to BMW's exacting standards, the 51717228081 crossmember provides critical structural reinforcement for vehicle front-end assemblies. This 51717228081 Crossmember replaces previous component 5111758437 while maintaining identical mounting geometry and load distribution characteristics. Manufactured from high-grade steel with specialized corrosion protection, the component serves as the primary anchor point for suspension components while distributing dynamic loads across the front chassis rails. The precisely calibrated geometry maintains wheel alignment specifications during cornering maneuvers while providing stable mounting surfaces for steering gear and engine cradle assemblies. Unlike generic alternatives, this 51717228081 Crossmember replicates the engineered flex characteristics that contribute to BMW's renowned driving dynamics.
During installation, the laser-cut mounting holes align perfectly with factory chassis points without requiring modifications or force-fitting procedures. The component's ribbed design increases torsional rigidity by 35% compared to flat-stock alternatives while minimizing added weight through optimized material distribution. Critical crumple zone geometries are maintained to preserve the vehicle's safety performance during impact events. The powder-coated finish provides durable protection against road debris and de-icing chemicals while maintaining electrical continuity for grounding systems. Vehicle owners will appreciate how this 51717228081 Crossmember restoration maintains original suspension kinematics and steering precision while adding enhanced resistance against stress fractures at high mileage intervals.
Vehicle Compatibility Specifications
This upper tie bar functions as a direct replacement component designed exclusively for BMW vehicles requiring enhanced front-end structural reinforcement. The 51717228081 crossmember maintains precise compatibility with 5 Series (F10) platforms manufactured between 2010-2016, specifically excluding M models and 4.4L engine configurations per factory specifications. The upgraded design supersedes previous part 5111758437 while maintaining identical mounting interfaces and clearance requirements. Critical dimensional parameters accommodate both standard and sport suspension configurations while providing proper clearance for steering gear components and hydraulic lines.
Mounting points align perfectly with factory brackets on both left and right chassis rails, accommodating variations in engine cradle designs across model years. The component precisely positions suspension mounting points to maintain BMW's specified wheel alignment parameters during suspension travel. The 51717228081 Crossmember accommodates all OEM accessory configurations including active steering systems and headlight washers while maintaining engineered crumple zone characteristics. Compatibility extends to both standard and xDrive variants while providing clearance for factory-installed underbody panels and aerodynamic components. Installation requires no modifications to adjacent components when replacing worn or damaged original equipment.
Engineering Specifications
Material Composition
Manufactured from high-strength low-alloy steel (HSLA 350) with a minimum yield strength of 350 MPa, the 51717228081 Crossmember withstands torsional loads exceeding 4,200 Nm. Surface treatment utilizes a triple-layer electro-coating process with zinc-nickel undercoating followed by epoxy primer and powder topcoat. This multilayer protection system creates a galvanic barrier that prevents oxidation while maintaining electrical conductivity for chassis grounding systems.
Structural Engineering
Hydraulic-formed rib patterns increase section modulus by 40% compared to previous designs while reducing weight through optimized material distribution. The precisely engineered flex zones absorb suspension impacts without transferring harmonic vibrations to the passenger compartment. The 51717228081 Crossmember features laser-cut mounting interfaces that maintain positional accuracy within ±0.2mm tolerance across production batches for perfect alignment with suspension components.
Precision Manufacturing
Robotic welding processes create consistent penetration depth at all critical joints while preventing heat distortion in thin-gauge areas. Computer-controlled fixturing maintains dimensional stability during assembly through 25-point positional verification. The 51717228081 Crossmember undergoes digital validation against CAD specifications using coordinate measuring machines to ensure micrometer-level accuracy across all load-bearing surfaces.
Compatible with: BMW 5 Series F10 (2010-2016 models excluding M variants and 4.4L engines). Replaces original components 51717228081 and 5111758437. Not affiliated with or endorsed by BMW AG.
