Control Arm 11.25in Screw-BJ Quad Bearing

The Control Arm 11.25in Screw-BJ Quad Bearing by U-B MACHINE is a precision suspension component engineered for high-performance off-road and racing applications where durability and articulation matter most. As a seasoned mechanic, you'll recognize that this control arm is built for vehicles that demand superior handling geometry and extended suspension travel. Whether you're upgrading a rock crawler, competition buggy, or extreme-duty 4x4, this component provides the kind of engineering reliability that separates amateur builds from championship-level rigs.

The quad bearing configuration is the technical standout here—four precision ball joints distributed across the arm's geometry dramatically reduce binding and allow smoother suspension articulation through full range of motion. The 11.25-inch length is optimized for specific suspension geometry applications where controlling camber gain, bump steer, and anti-squat characteristics is critical to both safety and performance. The screw-type ball joint connection ensures rock-solid adjustability and allows fine-tuning of suspension alignment angles without requiring complete disassembly, saving hours of shop time during setup or maintenance intervals.

This control arm suits builders and mechanics working on tube chassis vehicles, unlimited class competition buggies, and extreme-travel independent suspension systems where OEM components simply cannot handle the demands. The robust 4.64 lb construction and compact 12.35 x 1.6 x 13.3 inch profile make it suitable for tight packaging requirements without sacrificing structural integrity. Installation requires careful attention to suspension geometry—ensure all four bearing points are properly torqued and that alignment is verified post-installation to maintain the vehicle's intended handling characteristics and tire wear patterns.
