Crafted from high-carbon forged steel, our control arm undergoes a precise heat-treatment process, increasing its tensile strength by 30% compared to standard cast iron units. Rigorously tested to withstand over 500,000 fatigue cycles in simulated extreme conditions, it far exceeds ISO and OEM durability standards. This ensures exceptional resistance to impact and bending, guaranteeing long-term structural integrity and safety for the vehicle's suspension system.
We utilize original CAD data and 3D scanning technology to guarantee a 100% perfect fit. Every dimension, mounting point, and bushing alignment is meticulously verified to match the original specifications. This eliminates installation issues, premature wear, and abnormal noises, ensuring seamless integration and restoring the vehicle's original handling and alignment settings without any modifications.
The heart of our control arm lies in its upgraded polyurethane and rubber hybrid bushings. This proprietary compound reduces road noise and vibration transmission by up to 40% compared to standard alternatives. It effectively dampens shocks from rough roads, providing a smoother, quieter ride while significantly enhancing driving comfort and overall stability.
Every batch of our control arms is subject to a 10-step quality inspection process, including salt spray testing for over 720 hours to ensure superior corrosion resistance. Our production is certified by IATF 16949:2016, the international automotive quality management standard. This commitment to quality ensures you receive a reliable, safe, and long-lasting product backed by a 24-month warranty.
By providing precise wheel control and unwavering stability, our control arm directly contributes to vehicle safety. It improves road contact and steering response, especially during cornering and braking. This restores like-new driving dynamics, giving drivers confidence and enhanced control over their vehicle for a safer driving experience.

Here are specific application scenarios of Control Arm:
For optimal performance and safety, we recommend professional installation. Prior to fitting, always inspect the new control arm and all accompanying hardware for integrity. Utilize proper torque specifications (refer to packaging for values, typically 80-120 Nm for main bolts) and a calibrated torque wrench to secure all mounting points. A post-installation wheel alignment is mandatory to restore factory handling and prevent premature tire wear. For detailed instructions, scan the QR code on the package to access our video tutorial.
