UMI Performance 1047-R Upper Control Arm for S197 Mustang Rear Suspension

The UMI Performance 1047-R is a high-performance upper rear control arm designed to replace the factory stamped control arm on S197 Mustang chassis vehicles. This upgrade reduces wheel hop, increases traction, and eliminates the flex and deflection issues common with factory rubber bushings under hard acceleration and aggressive driving.

Key Features:

• CNC-machined mounting bracket constructed from 0.250-inch thick steel for precision tolerances
• QA1 Chrome Moly spherical rod end with Teflon/Kevlar self-lubricating race for bind-free operation
• 4140 Chrome Moly heat-treated left and right hand adjuster for maximum strength
• 4140 Chrome Moly threaded tube adaptor ensures thread durability
• MIG and TIG welded construction for superior strength
• On-car adjustability for quick pinion angle changes without removal
• 100% bolt-on installation using factory hardware
• Durable powder coat finish available in Black or Red

Performance Benefits:

• Eliminates factory control arm flex for improved traction during launches
• Allows proper suspension articulation for high-performance handling
• Enables suspension correction and pinion angle adjustment for lowered vehicles
• Works excellent as a solid bushing drag race control arm

The S197 Mustang uses a 3-link rear suspension system with a panhard bar. Under hard loads, factory components tend to flex and rubber bushings deflect, leading to poor traction and erratic handling. This upper control arm provides the rigidity needed for better vehicle control and consistent performance.

Note: UMI Performance offers Part #1058 spacer kit (sold separately) to address the factory oversized hole issue at the chassis mount, eliminating clunking and bolt shift during acceleration and braking.
