This reinforced auto rear beam tube is engineered to enhance the structural integrity of vehicle rear suspension systems, critical for improving handling and load-bearing capacity.

|---|---|
Crafted from 16Mn alloy steel (heat-treated for strength), it provides 30% higher torsional strength than standard carbon steel rear beam tubes—making it suitable for passenger cars, SUVs, and light commercial vehicles. Compliant with SAE J2632 (automotive axle components), it is available in diameters from 50mm to 114mm and wall thicknesses from 4.0mm to 10.0mm, with customizable lengths to fit specific vehicle models.
Reinforced Strength: 16Mn alloy steel (0.12–0.20% carbon, 1.20–1.60% manganese) delivers tensile strength ≥ 510 MPa, yield strength ≥ 345 MPa, and torsional strength ≥ 350 MPa (per SAE J1981). The tube’s seamless construction and reinforced weld points (at flange connections) resist bending and twisting under heavy loads (up to 3000 kg rear axle load).
Load-Bearing Capacity: Supports maximum rear axle loads up to 3500 kg (per SAE J2632 testing), ideal for SUVs and light trucks (e.g., Ford Ranger, Toyota Hilux) carrying heavy cargo or towing trailers (up to 2.5 tons). The tube’s wall thickness is optimized at stress points (e.g., spring mounts) to prevent sagging.
Welding Compatibility: Excellent weldability with MIG and TIG processes, forming joints that maintain 85% of the base material strength. The tube’s consistent chemical composition ensures uniform heat absorption during welding, avoiding brittle zones in the rear beam assembly.
Corrosion Resistance: Surface treated with hot-dip galvanization (80–120μm zinc coating, per ISO 10289) and passivation, withstanding 5000 hours of salt spray testing (ASTM B117). This protects against road salt, mud, and moisture, extending service life to 15+ years (double that of ungalvanized tubes).
Passenger Cars: Used in midsize sedans and hatchbacks (e.g., Toyota Corolla, Volkswagen Golf) to improve rear suspension stability. The tube reduces body roll by 20% during cornering, enhancing ride comfort and safety.
SUVs and Crossovers: Ideal for 5-seater and 7-seater SUVs (e.g., Honda CR-V, Ford Explorer) that carry multiple passengers and cargo. The reinforced design maintains rear axle alignment even with a full load (800–1000 kg), preventing uneven tire wear.
Light Commercial Vehicles: Used in pickup trucks and delivery vans (e.g., Mercedes-Benz Citan, Ford Transit Connect) for their load capacity. The tube’s torsional strength prevents rear beam twist when towing trailers or carrying heavy payloads (up to 1.5 tons).
Q: What vehicle models is it compatible with, and do you offer OEM matching?
A: It is compatible with 50+ popular models, including Toyota (Corolla 2014+, Hilux 2016+), Honda (CR-V 2017+, Civic 2016+), Ford (Explorer 2015+, Ranger 2019+), and Volkswagen (Golf 2013+, Tiguan 2016+). We offer OEM dimension matching with a sample or part number, with a lead time of 7–10 working days.
Q: How is it tested for durability, and what quality assurance do you provide?
A: Each tube undergoes 100,000-cycle torsional fatigue testing (simulating 200,000 km of use) and impact testing (50 J at -40℃) with no deformation or cracking. We are IATF 16949 certified, and all tubes come with a 3-year/100,000 km warranty for automotive use.
Q: Can it be customized for lifted vehicles, and what modifications are needed?
A: Yes—we offer extended-length tubes for 2–4 inch suspension lifts (custom lengths from 300mm to 600mm). Lifted vehicle modifications include reinforced flange connections (to handle increased stress) and adjusted spring mount positions, ensuring proper suspension geometry. Lead time for custom lifted versions is 10–14 working days.
