Original quality control arm with OE number 4M0407505B is a vital front upper suspension component compatible with Audi Q5L, Q8 and other MLB Evo platform vehicles including Audi Q7, A6 C8, A7, Volkswagen Touareg and Porsche Cayenne. Manufactured strictly to OEM specifications, this control arm is forged from high-strength lightweight aluminum alloy with CNC precision processing, delivering excellent structural rigidity, impact resistance and deformation resistance, perfectly adapting to SUV heavy-load driving, highway cruising and complex rough road conditions.
Equipped with high-temperature resistant elastic rubber bushing and fully sealed wear-resistant ball joint, it firmly connects the subframe and steering knuckle to absorb road vibration, restrict wheel offset, improve steering accuracy, vehicle handling stability and driving comfort. When the original control arm has cracked aging bushings, worn ball joint or deformed arm, the vehicle will produce clunking noises over bumps, steering deviation, irregular tire wear and high-speed steering wheel vibration.
Each control arm passes fatigue durability, temperature cycle aging and salt spray anti-corrosion tests to ensure long-term stable performance. Original standard mounting dimensions support direct bolt-on replacement without modification, saving maintenance time and labor cost. We have abundant spot inventory, support bulk wholesale, mixed orders and global fast delivery, which makes it a reliable aftermarket spare part for chassis repair.
