UMI Performance 1045-R Upper Control Arm Mount with Instant Center Adjustment

The UMI Performance 1045-R is a heavy-duty upper control arm mount designed as a direct replacement for the factory stamped steel mount. Engineered for GM A-Body and G-Body vehicles, this mount provides increased strength and adjustability for improved suspension performance.

Key Features:

• CNC machined from 1/2-inch thick mild steel for superior strength—twice the thickness of factory mounts
• Built-in instant center adjustment with two mounting hole locations for tuning traction and handling characteristics
• 14mm mounting hole corrects the clunking issue commonly found with factory upper control arm mounts
• Direct bolt-on installation reuses factory hardware—no welding or drilling required
• Durable powder coat finish for long-lasting corrosion resistance
• Precision CNC machining ensures exact tolerances and perfect fitment

By relocating the upper control arm mounting position, you can adjust the vehicle's instant center to optimize weight transfer during acceleration, improving rear-end traction for drag racing or performance street driving. The heavy-duty construction eliminates flex and provides a solid foundation for high-performance control arms.
