UMI Performance 203538-B Suspension Trailing Arm Panhard Rod Kit with Roto-Joints

The UMI Performance 203538-B is a complete suspension control arm and panhard bar kit designed for serious enthusiasts seeking maximum performance and precise rear end geometry control. This comprehensive kit features UMI's innovative Roto-Joint technology on all mounting points, delivering bind-free suspension articulation with zero bushing deflection for improved traction and handling.

Key Features:

• Complete kit includes adjustable control arms and panhard bar with on-car adjustment capability
• Roto-Joints installed at all mounting points for 28 degrees of unrestricted rotational movement
• CNC machined 4140 chromoly threaded tube adapters with left and right hand threads
• Constructed from DOM mild steel tubing, fully TIG welded for maximum strength
• Hard chrome plated 4140 chromoly spherical balls with delrin race bushings
• Durable powder coat finish for corrosion resistance and appearance
• Uses OEM mounting hardware for direct installation
• Greaseable and rebuildable design for long-term serviceability
• Includes spanner wrench for Roto-Joint adjustment and maintenance
• Ships fully assembled and ready to install

Performance Benefits:

• Eliminates suspension bind through spherical articulation design
• Reduces wheel hop and improves traction compared to rubber or polyurethane bushings
• Allows precise rear end centering after lowering or during rear end swaps
• Easy length adjustment without removal - just loosen jam nuts and turn
• Maintains quiet, smooth operation suitable for street and track use
• Delrin race absorbs shock and road noise while preventing deflection

About Roto-Joint Technology:

UMI's Roto-Joint (Rotational Joint) combines the precision of a spherical rod end with the streetable characteristics of a traditional bushing. The 4140 chromoly spherical ball rotates within a CNC machined delrin race that's contoured for unrestricted movement. Delrin was chosen for its exceptional wear resistance, high tensile strength, and ability to maintain physical properties under stress. The adjustable design allows you to tighten the adjuster ring as the delrin race wears, and the entire joint is 100% rebuildable for long-term cost effectiveness.

Ideal for lowered vehicles, road race applications, autocross, or any performance build requiring precise rear suspension geometry and maximum traction. The kit provides the professional-grade adjustability needed to dial in your suspension setup while maintaining excellent street manners.
