UMI Performance 2017OFCM-B Lower Control Arms with Offset Bushings

The UMI Performance 2017OFCM-B lower control arms are precision-engineered for race applications and light-duty street use on muscle cars and performance vehicles. These double-adjustable trailing arms feature offset bushing design that moves the control arm inward 0.375 inches, providing critical tire clearance for wide tires and mini-tub installations.

Construction and Materials:

• TIG welded from 1.250-inch x 0.120-inch DOM steel tubing or optional 1.250-inch x 0.095-inch 4130 chromoly steel for increased strength and reduced weight
• In-house machined 4130 chromoly tube adaptors for superior thread durability
• CNC machined lightweight aluminum offset bushings that reposition the control arm 3/8-inch inward
• Durable powder coat finish available in red or black
• Stronger and lighter than factory control arms

Performance Features:

• Premium Teflon-lined, high load capacity spherical rod ends that are self-lubricating
• Double adjustment capability allows 1 inch longer or 1 inch shorter than factory length for on-car tuning
• Eliminates rear suspension bind while providing solid bushing control arm performance
• Allows easy adjustments for wider tire clearance and centering aftermarket rear axles
• Pre-set to factory length for straightforward installation
• No sway bar mounting holes—designed for aftermarket sway bars that mount independently

Installation:

• Reuses factory hardware or can be paired with UMI hardware kit P/N 4001 (sold separately)
• Designed and manufactured in Philipsburg, Pennsylvania, USA

The offset bushing design makes these control arms ideal for achieving maximum clearance when running large tires or mini-tub configurations. The spherical rod ends provide a solid foundation for race applications while the double adjustment feature enables precise tuning for optimal suspension geometry.
