Description
The Camburg 1 inch 4130 Chromoly Uniball Cup is designed for high-performance automotive applications, including building custom upper and lower control arms, spindles, or links. Machined in-house from premium US 4130 chromoly steel, these cups offer superior strength and durability compared to standard mild steel or imported materials. The CNC machining process includes not only the cup’s internal features but also the outer diameter, which is finished to remove material scale and improve weld quality. This ensures a clean, reliable weld each time, whether MIG or TIG welding is used. Heat treatment options further enhance the cup’s strength and longevity, making it suitable for demanding off-road or racing environments. The 1.50-inch width provides a wider base, ideal for lower control arms or links requiring maximum weld attachment area, contributing to improved structural integrity and performance in your suspension system. These cups are sold individually and do not include snap rings or bearings, so proper assembly and installation are essential for optimal operation. Whether you’re customizing your vehicle’s suspension or upgrading existing components, the Camburg 4130 Uniball Cup offers a high-quality, precision-machined solution that ensures maximum misalignment capability and strength for your build.
