QA1 KFR12SZ 3-Piece Carbon Fiber Female Rod End 3/4-16 RH Thread with Zerk Fitting

The QA1 KFR12SZ is a high-performance 3-piece female rod end featuring a carbon fiber reinforced housing and a 3/4" bore spherical ball. Engineered by QA1 Precision Products for demanding racing, off-road, and performance street applications, this rod end delivers superior strength-to-weight characteristics compared to traditional steel alternatives.

The 3-piece construction utilizes a precision-ground alloy steel ball seated in a carbon fiber composite race, providing excellent load-bearing capacity with reduced weight. The included Zerk grease fitting (ZRK) allows for routine lubrication to extend service life and maintain smooth articulation under load.

Key Features:

• 3-Piece Design: Carbon fiber reinforced housing with precision alloy steel ball for high strength and reduced weight
• 3/4" Bore: Accepts 3/4" diameter stud or bolt
• 3/4-16 Right-Hand Thread: Standard RH thread for easy integration into custom fabricated linkages
• Zerk Grease Fitting: Serviceable design allows lubrication to maximize bearing life
• Female Configuration: Internally threaded housing for clean installation into tie rod tubes and fabricated links
• High Misalignment Capability: Spherical ball design accommodates angular misalignment in steering and suspension applications

QA1 rod ends are a trusted choice among race fabricators, suspension builders, and performance enthusiasts. The KFR12SZ is commonly used in custom steering tie rod assemblies, suspension links, panhard bars, and chassis bracing where precise articulation and durability are critical.
