澳大利亚采购需求：卡丁车轮毂、卡丁车前轮毂、卡丁车离合器、链轮托架、卡丁车轴键、卡丁车主轴

I'm looking to procure several specific components for our upcoming project. We need engine mounts with a 5-degree angle, short hubs measuring 40mm, sprocket carriers also at 40mm, and tie rods that are 280mm in length. All of these items should be finished in black anodized material for durability and aesthetics. Please provide your pricing, lead times, and any bulk order discounts available. Looking forward to your response!
