The SPC Performance Builder Series Cartridge Ball Joint (MPN 15221) is a modern, maintenance-free solution designed specifically for custom front upper control arm projects. Unlike standard OE replacement joints, this builder series component is engineered for fabrication, allowing it to be integrated into custom designs using technical sheets and .STP files. Assembled in Colorado, it provides the articulation and strength required for high-performance off-road and custom suspension geometries.

• Increased Articulation: Oversized ball generates 80° of articulation to prevent binding in long-travel setups.
• Enhanced Strength: Forged ball stud features a 25% increase in neck cross-section compared to OE joints.
• Corrosion Resistance: E-Nickel coating on the ball stud ensures smooth operation and protection against the elements.
• Maintenance-Free Design: Fully sealed boot and modern grease formula keep contaminants out without the need for periodic greasing.
• Precision Performance: One-piece polymer race provides low, smooth turning torque consistent with modern OE standards.
• Manufacturer Part Number: 15221

Note: This is not a direct OE replacement ball joint; it is intended for use in custom-fabricated control arms or aftermarket designs.
