Why Quality Control Matters So Much in the Automotive Aftermarket

Your customers rely on you for safe, dependable products. Subpar parts don't just lead to returns and warranty issues; they can severely damage your credibility and reputation.

We conduct regular internal and external audits, constantly refining our systems and processes to ensure continuous improvement. Whether you're sourcing ball joints, pitman arms, or sway bar links, every product we manufacture undergoes the same rigorous scrutiny.

Proven Manufacturing Standards: The Foundation of Quality

All 5,000+ part numbers we produce are backed by a stringent manufacturing documentation process, ensuring consistency and reliability:

• Material Certification: All materials are certified to confirm their properties and compliance with specific standards to meet the required specifications for intended use for each part.
• Heat Treatment: This critical process is adjusted specifically for various applications, with detailed profile documents submitted for every batch to ensure optimal performance.
• Precision Machining: All machining is executed in certified facilities and verified with state-of-the-art measuring equipment including Faro, 3D Projector, Coordinate Measuring Machines (CMM) for unparalleled accuracy.
  
• Dimensional Reports: Required for every production run to ensure parts are within specified tolerance for proper fitment.
  
• Surface Coatings: We offer a wide range of protective coatings, including zinc, manganese phosphate, e-coat, powder coating, and dacrotizing, based on your specific product requirements for maximum durability.
  

From control arms to ball joints, every part is made to deliver consistent quality and long-term reliability. Our rigorous process ensures performance that truly meets the real-world demands of your customers’ steering and suspension systems.

Real-World Testing for Real-World Confidence

Our testing protocols for product approval are designed to simulate the actual stresses and conditions your customers’ vehicles encounter on the road to ensure our parts meet the specifications:

• Pull-Out Tests: We rigorously test that ball joints can withstand the forces of real-world vehicle operation.
• Ball Stud Drop Impact Testing: This crucial process simulates real-world stress to validate durability. It involves dropping a precisely weighted ball from a specified height onto the ball stud to mimic impact forces encountered during normal vehicle operation, such as hitting potholes. The ball stud's response is meticulously measured for deformation, cracks, or other damage, with the assessment criteria based on its ability to withstand the impact without significant damage and maintain structural integrity. This rigorous testing regimen ensures that our suspension parts meet the safety and performance standards.
• Salt Spray Tests: We assess the corrosion resistance of different materials and coatings to ensure the quality and durability of the products meet the requirements in various demanding environments.

These hands-on tests ensure that our ball joints, drag links, and rack ends not only meet but exceed aftermarket standards, giving you and your customers confidence.
