What Makes Us Different

All HQMS products are highly durable and offer excellent wear and tear resistance in highly aggressive environments. We partner with only ISO-certified manufacturers operating the same facilities that make major OEM parts.

Made To Last

We follow a strict testing methodology, applying the final product on OEM engines running continuously for 3 days to simulate real-life scenarios. This process involves extremely tough tests such as engine rotation, resistance, and heavy load to ensure the product is compliant with the stringent standards.

Customer Service

Every customer should expect the best service. That’s why we have a customer service commitment to ensure we meet your expectations every time you deal with us. Each HQMS employee you talk to is committed to these seven customer service principles.

  • We’ll recommend products suited to your business.
  • We’ll take the time to explain the product featured and benefits, and its price.
  • We’ll let you know how long it will take to fulfill your order. And we’ll commit to that timeframe to our best capabilities.

Our customers are our partners, and we regularly seek their input to ensure the best satisfaction.
