This product is a dedicated rubber bushing for the rear suspension control arms of imported BMW 1 Series, 3 Series, X1, and Brilliance BMW 3 Series vehicles. Installed at the hinge point between the control arm and the subframe, it is a key damping component in the chassis damping system. During vehicle operation, the suspension is subjected to continuous impacts and periodic vibrations from the road surface. If the bushing rubber ages and cracks, or if the inner bore wears and becomes loose, it will directly lead to problems such as chassis noise, vague steering, and uneven tire wear. This product utilizes the elastic deformation of its high-vulcanized rubber body to convert the vibration energy between the metal parts and the vehicle body into heat energy dissipation, effectively blocking the vibration transmission path. Simultaneously, it maintains the geometric position of the control arm under loads in all directions, ensuring long-term stability of suspension motion accuracy and driving comfort. Suitable for daily urban driving and long-distance highway cruising, it is one of the frequently worn parts in BMW chassis maintenance.

Outer diameter 45mm: Fits tightly to the inner wall of the control arm mounting hole, with no radial clearance after pressing in, preventing loosening or displacement during movement.
12mm Inner Diameter: Corresponds to the control arm bolt specifications, with strictly controlled hole roundness, ensuring smooth bolt insertion and even distribution of preload torque.
48mm Installation Thickness: Completely covers the control arm hinge end face, with the rubber body fully encasing the metal liner, ensuring sufficient deformation allowance under stress in all directions.
26mm Flange Diameter: Precise flange stop limit, requiring no additional adjustment after installation, ensuring excellent alignment.

Outstanding Vibration and Noise Reduction: The rubber body uses a high-vulcanization fatigue-resistant formula, with an elastic modulus consistent with the original factory specifications. It effectively isolates high-frequency road vibrations from the vehicle body, eliminating chassis metal-on-metal collision noises, providing a driving experience close to that of a new car.
High Material Durability: The rubber material possesses excellent oil resistance, ozone resistance, and aging resistance, maintaining good elasticity in both high-temperature summers and severe winters, resisting cracking and hardening, and ensuring a long service life. The metal frame is precision die-cast and treated with rust prevention, preventing corrosion over long-term use.
Wide compatibility: Directly replaces original OEM specifications, compatible with multiple BMW models including the imported 1 Series, 3 Series, X1, and Brilliance BMW 3 Series. No modification required, easy installation, suitable for 4S stores and independent repair shops.
Precise and reliable dimensions: Strictly controlled tolerances for all key dimensions, perfectly matching the original mounting holes. After pressing in, it is firmly secured without looseness or misalignment, ensuring the chassis geometry accuracy remains unaffected.
