This tubular crossbeam is horizontally installed between the left and right frame longitudinal beams of the truck chassis, located directly under the rear side of the engine and gearbox assembly. Both ends are bolted and fixed to the inner side of the frame longitudinal beams. The upper bracket matches the engine rear rubber mount, serving as the core mounting base for the rear support of the power assembly with precise installation size and perfect fit for the original chassis structure.
Product Overview
The WG9731590135 tubular crossbeam is a core structural part of heavy-duty truck chassis. Installed between the frame longitudinal beams and under the rear of the power assembly, it acts as the main load-bearing and positioning base for the engine rear suspension system.
Product Functions & Features
Heavy Load Bearing and Uniform Load Distribution: This crossbeam bears the full weight of the engine and gearbox assembly and evenly transfers the pressure to the chassis frame. The hollow tubular structure achieves lightweight design while maintaining outstanding bending and compression resistance.
Precise Positioning and Vibration Stabilization: Effectively limits the longitudinal and lateral displacement of the power assembly during acceleration, braking and bumpy driving. Reduces engine shaking and torsion, protecting drive components from fatigue damage.
Chassis Reinforcement and Improved Torsion Resistance: As a key horizontal connecting component of the frame, it greatly enhances the overall rigidity and torsion resistance of the chassis, preventing deformation and cracking under harsh working conditions.
Multi-functional Mounting Base: Reserved standard mounting points support the installation of air reservoir brackets, pipeline clamps, wiring harness fasteners, and other accessories for neat chassis layout.
Quality Advantages
Manufactured in strict accordance with OEM original size standards for high compatibility and direct replacement without modification. All welds are professionally inspected to eliminate defects. The electrophoretic surface treatment provides superior rust and corrosion resistance, adapting to various harsh working environments with high stability and long service life.
Replacement Application Scenarios
Suitable for replacing original beams with deformation, cracking, dent, weld tearing and aging damage. Also applicable to chassis overhaul, accident repair and chassis reinforcement upgrade of heavy-duty trucks.
