UMI Performance 2013-R Lower Control Arms - Adjustable Chrome Moly

The UMI Performance 2013-R lower control arms deliver professional-grade suspension performance with on-car adjustability for street performance and enthusiast applications. Constructed from premium 1.250" x 0.095" 4130 chromoly steel, these control arms provide exceptional strength while reducing weight compared to stock components.

Key Features:

• On-car adjustable design using chromoly heat-treated adjuster for quick length changes
• Spherical chromoly and Teflon-lined rod ends paired with polyurethane bushings
• CNC machined tubing and 4140 chromoly threaded tube adaptors for precise fitment
• Fully TIG welded construction for maximum strength and durability
• Durable powder coat finish for long-lasting corrosion resistance
• Uses OEM hardware for straightforward installation
• Ships fully assembled and ready to install

Design Benefits:

The hybrid bushing configuration features polyurethane bushings on the chassis side to absorb road noise and vibration, while spherical rod ends on the axle side provide precise suspension geometry and improved handling response. The on-car adjustability allows you to fine-tune control arm length by simply loosening two jam nuts and turning the chromoly adjuster—no need to remove the arms from the vehicle.

Applications:

Ideal for fitting larger tires by adjusting rear axle position forward or backward. Essential for aftermarket rear end installations to properly center the housing and prevent tire rubbing. The adjustable design ensures proper pinion angle and suspension geometry for optimal traction and handling.
