Made using cold forging and high-pressure forming technology, the main material is high-strength boron steel (tensile strength ≥ 500MPa) or aviation grade aluminum alloy. Key stress points are subjected to robot laser welding, and the weld strength reaches over 95% of the base metal. After 1 million bench fatigue tests and ± 3 ° torsional stiffness tests, it is ensured that there is no deformation or fracture under extreme road conditions, and the service life is increased by 50%.

2. Precision OEM Specification Matching

Based on 3D laser scanning original part data development, the ball head swing angle is ± 30 ° without interference, and the lining hardness is maintained at Shore 70 ± 5A. The installation hole tolerance is controlled within ± 0.3mm to ensure non-destructive direct installation with the subframe and wheel hub assembly. Support precise matching through original OE codes to avoid positioning errors caused by size deviations.

3. Comprehensive Anti Corrosion Protection Solution | Comprehensive Anti Corrosion Protection

Adopting 8 surface treatment processes: including zinc nickel coating (thickness ≥ 12 μ m)+epoxy primer+acrylic topcoat. Through 500 hours of neutral salt spray testing (exceeding industry standards by 2 times), the corrosion resistance has been improved by 300%. Special coatings can resist snow melting agents and seawater corrosion, ensuring safe driving in cold/coastal areas.

4. Performance Enhancement&Safety Assurance

The hydraulic liner adopts a dual oil passage design, which increases the shock absorption efficiency by 40%. The ball head is made of PTFE+Kevlar composite material, with a wear life of up to 150000 kilometers. After installation, it can eliminate problems such as steering wheel shaking and tire uneven wear, maintain the outer angle of the rear wheels at the standard value of -1.5 °± 0.2 °, and ensure braking stability.

5. Quality Certification&After Sales

Certified according to the IATF 16949 system, each component comes with a laser traceability code. We offer a 12-month extended warranty and support returns and exchanges within one year without any reason. All products have undergone 100% dynamic balance testing and final inspection using a coordinate measuring instrument, with a quality consistency of 99.8%.

Technical Parameters

1. Primary Material:

Made of high-strength cold forged steel or T6-6061 aircraft grade aluminum alloy, with a tensile strength of ≥ 500 MPa and a yield strength of ≥ 350 MPa, ensuring structural integrity and no plastic deformation under extreme loads.

2. Connection Specifications:

The ball head assembly adopts hot pressing assembly technology, with a swing angle of ≥ ± 30 ° and a working life of up to 150000 kilometers. The bushing is made of OE grade hydraulic bushing or high-density polyurethane material, with a Shore hardness of 70A ± 5, providing excellent vibration isolation and control support.

3. Surface Treatment:

After 8 layers of protective treatment, including zinc nickel coating (thickness ≥ 12 μ m), epoxy primer, and acrylic anti stone impact topcoat. Through 500 hours of neutral salt spray test (NSS Test), the corrosion resistance far exceeds the original factory standard, effectively coping with harsh environments.

4. Precision&Compatibility:

All installation holes are formed by CNC precision machining centers, with a hole diameter tolerance controlled within ± 0.2mm, ensuring stress free in-situ installation with the subframe and wheel hub bearing seat. Perfectly match the original OE number, without the need for adjustment or modification.

5. Load&Performance:

Static radial load capacity ≥ 4500 kg, fatigue test passed 1 million ± 3 ° torsion cycles. The starting torque of the ball head should be maintained within the standard range of 0.8~3.0 N · m, ensuring no looseness and smooth turning back to the correct direction.

6. Certification&Warranty:

The manufacturing system has passed the IATF 16949:2016 international automotive quality certification, and the products comply with DOT and ECE R90 safety standards. Provide a 12-month extended quality guarantee.

Product Uses

Here are specific application scenarios of Left Rear Suspension Control Arm:

1.Chassis Repair After Collision

When the rear of the vehicle encounters a collision or frequently travels on bumpy roads, the control arm may undergo bending deformation that is difficult to see to the naked eye. This can lead to inaccurate four-wheel alignment data, causing abnormal tire wear and deviation. Replacing the control arm with the original factory specifications can accurately restore the suspension geometry parameters, ensuring vehicle stability and safety during driving.

2. Solve Chassis Noises&Loose Handling

If there is a "clunking" metal impact sound coming from the left rear wheel when passing a speed bump, or if the rear of the car feels laterally swaying while driving at high speed, it is usually caused by a broken control arm liner or excessive ball head clearance. Replacing the new assembly can immediately eliminate abnormal noise, restore a compact and solid chassis texture, and enhance driving confidence.

3. Addressing High Mileage Vehicle Aging

Vehicles that have traveled over 80000 kilometers may experience hardening and cracking of the control arm rubber lining, leading to fatigue stress on metal components. It is recommended to perform preventive replacement during regular maintenance to avoid sudden malfunctions. This is crucial for maintaining suspension accuracy and extending tire life.

4. Root cause treatment of abnormal tire wear | Solving Abnormal Tire Wear

When the left rear tire is found to have uneven wear (severe wear on the inner or outer side), even after adjusting the positioning data, it quickly recurs, often due to the deformation of the control arm causing the tilt angle to be unable to be adjusted. Replacing with new parts can fundamentally solve the wear problem and avoid continuous waste of tire costs.

5. Preparation for Full Suspension Upgrade

When you are preparing to replace suspension components such as shock absorbers and springs, the old control arm will limit the performance of the new components. Installing a new control arm can ensure that the entire suspension system is in optimal working condition and is a key investment in chassis system maintenance.

Product Operate Guide

1. Professional installation suggestions

We strongly recommend that professional technicians use specialized tools to complete the installation. The operation requires lifting the vehicle, dismantling tires and related components, and involves suspension geometry adjustment, which poses a high safety risk. Please make sure to prepare professional tools such as torque wrenches and ball joint separators.

2. Key operating points

Thoroughly clean the connection parts before installation. Use a torque wrench to tighten all bolts step by step according to the original factory specifications (usually 80-120N · m). Special attention should be paid to tightening the lining bolts when the vehicle is on the ground to avoid abnormal pre tightening force of the lining. After installation, four-wheel alignment must be performed to ensure that the rear wheel inclination and toe angle meet the standard values.

3. Post installation inspection

After installation, a road test is required to test the vehicle's straight-line stability and steering return function in a safe location to ensure no abnormal noise. It is recommended to recheck the bolt tightening status every 500 kilometers of driving.
