Quality Products

Aftermarket replacement (spare) parts provide the most efficient and cost-effective solution for your business. Because genuine OEM parts are often very expensive, the cost per hour on quality aftermarket replacement parts will almost always win over OEM. That is why USR Parts only offers the highest quality aftermarket parts hand selected from brands that are proven and trusted.

Superior Customer Service

We believe that to truly offer "superior customer service" we must first understand what is important to our customers, and the only way to know that is to ask them. Every aspect of our business, whether it's navigating our website, using our online order management system, receiving a shipment or talking with a representative, has all been strategically developed to satisfy the needs of our clients.
