Rear Trailing Arm Bushing
Installed at the Rear Trailing Arm Connection
The rear trailing arm bushing installs between the rear trailing arm and the body or subframe. This part handles the longitudinal and lateral forces from the rear suspension during driving. Our product uses high-elasticity natural rubber and precision-machined metal inner and outer tubes. These materials bond through a high-temperature, high-pressure vulcanization process. This design allows the product to keep stable stiffness and excellent rebound properties. It can handle the longitudinal impact loads from acceleration and braking. This product fits passenger cars and SUVs. It is a direct replacement for original parts.
Critical Bond Strength and Quality Control

We strictly control the vulcanization temperature and time for the rear trailing arm bushing. This ensures the rubber-to-metal bond strength reaches industry-leading levels. This prevents de-bonding or cracking during use. Every batch of product goes through 100% visual inspection and dimensional checking before shipment. This guarantees product consistency and reliability. We supply this product to Anhui Zhongding and ASIMCO. Annual capacity exceeds 350,000 pieces.
