Belt Tensioner Aluminum Arm

​

 This is Aluminum arm and base parts die-cast in my factory. We adopt the high performance raw material aluminium ingot Si9Cu3 in China. It's very important to make sure the part stable hardness durable without any blow holes. It load bearing the power when it is working in the engine. If got any fake quality,it would be broken when strong power.

The surface burr treatment clean and smooth same as DAYCO performance. Any defects semi-products are throw-out and never passed.

Ouchai belt tensioner is your best choice.
