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

The UMI Performance 2017OFCM-R lower control arms are engineered for race applications and light-duty street use on GM A-Body, G-Body, and similar rear-wheel-drive platforms. These double-adjustable trailing arms feature an offset bushing design that moves the control arm inward 0.375" for enhanced tire clearance when running wide tires or mini-tub configurations.

Construction & Materials:

• TIG welded from 1.250" x 0.120" DOM tubing or optional 1.250" x 0.095" 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
• Durable powder coat finish available in red or black

Performance Features:

• Premium Teflon-lined, high-load capacity spherical rod ends that are self-lubricating and eliminate rear suspension bind
• Double adjustment allows 1" longer or 1" shorter than factory length for on-car changes
• Supplied pre-set to factory length for easy installation
• Offset bushing design provides 3/8" additional inboard positioning compared to standard control arms
• Stronger and lighter than factory control arms

Installation & Compatibility:

• Reuses factory hardware or accepts optional UMI hardware kit P/N 4001
• Designed for aftermarket sway bars that do not attach to control arms (no sway bar holes)
• Ideal for centering aftermarket rear ends and achieving maximum tire clearance
• Designed and manufactured in Philipsburg, Pennsylvania, USA

These race-style lower control arms deliver the adjustability and strength needed for serious performance applications while providing the clearance required for aggressive tire fitment.
