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

The UMI Performance 1047-B upper rear control arm is a direct bolt-on replacement designed to eliminate wheel hop and improve traction on S197 Mustang chassis vehicles. This high-strength control arm replaces the factory stamped component, addressing the flex and deflection issues that lead to poor traction and erratic handling under hard loads.

Key Features:

• QA1 Chrome Moly spherical rod end with Teflon/Kevlar self-lubricating race for bind-free suspension articulation
• 4140 Chrome Moly heat-treated left and right hand adjuster for maximum strength
• Mounting bracket constructed from 0.250" thick steel, CNC machined for precision tolerances
• MIG and TIG welded construction for superior durability
• 4140 Chrome Moly threaded tube adaptor ensures long-term thread durability
• On-car adjustment capability without removal - simply turn the wrench to adjust pinion angle
• Durable powder coat finish available in Black or Red
• Reuses factory hardware for easy installation

Performance Benefits:

The S197 Mustang's 3-link rear suspension with panhard bar relies on control arms that can flex under load, causing the rubber bushings to deflect and compromise traction. This UMI upper control arm eliminates that flex with its rigid construction and spherical bearing design, allowing for better vehicle control and improved traction during launches. The adjustable design makes it ideal for both high-performance handling applications and drag racing setups.

Adjustment Capability:

The built-in adjustment feature allows for quick pinion angle changes to optimize suspension geometry, particularly useful when correcting suspension geometry on lowered vehicles or fine-tuning for specific track conditions.

Compatibility Note:

Works with UMI Part #1058 spacer kit (sold separately), which addresses the factory's oversized 16mm chassis hole by stepping it down to the correct 14mm diameter, eliminating slop and clunking noises from the upper control arm mount area.
