Lower Control Arm Mount Pair

The U-B Machine Lower Control Arm Mount Pair (MPN 46-1092) is a heavy-duty weld-on trailing arm bracket system engineered for suspension geometry correction and chassis reinforcement on GM A-Body and G-Body platforms. This matched pair delivers the structural integrity needed for serious chassis work, street rod fabrication, and high-performance suspension upgrades where factory geometry requires modification or enhancement.

Built from steel in natural finish, each bracket in this pair weighs 3.7 lbs combined and measures 8.25 × 3.8 × 8.55 inches, providing substantial material thickness and weld surface area for permanent fastening. The weld-on design eliminates reliance on factory attachment points, allowing builders to relocate or reinforce lower control arm mounting positions for improved suspension kinematics, weight distribution, or clearance requirements. Natural finish accepts welding preparation and finishing in accordance with builder specifications without factory coating interference.

Fabricators and restoration specialists working A-Body and G-Body platforms—including Chevrolet Chevelle, Malibu, Monte Carlo, and Pontiac GTO builds—rely on properly engineered control arm mounts to maintain suspension compliance and chassis stiffness. This pair addresses applications requiring custom geometry setups, independent rear suspension conversions, or structural reinforcement where OEM brackets are insufficient. Careful welding and proper alignment verification after installation are essential for safety and performance.

U-B Machine has established a reputation among serious fabricators for producing robust, purpose-built suspension components that prioritize structural integrity over cosmetic appeal. These brackets represent engineering-first design for builders who understand that chassis dynamics depend on precise control arm positioning and load-rated attachment points.
