Control arms are steering and driving components of suspension system, playing the role of transmitting the forces on the wheels to the car body; meanwhile, keeping the wheels following a certain track. Control arms connect the wheels with car body elastically via ball-joints or bushings. Yunqi applies professional technology and good equipment to develop and manufacture various control arms for you; through fatigue and stiffness testing we unremittingly adjust the performance, guaranteeing the durability of our products, ensuring proper stiffness characteristic, effectively optimizing riding stability, supporting car body and reducing NVH.

We natural rubber material, which is odorless with stable property. 

For each product, we have calculated its best vulcanizing time, 

temperature and pressure through many times test.
All of our products go through 600000 times cycle of fatigue test, 

ensuring the durability.
