UMI Performance 4022-R Rear Lower Control Arms Lift Bars with Adjustable Mounting

The UMI Performance 4022-R rear lower control arms (lift bars) are engineered to dramatically improve traction and reduce wheel hop on performance vehicles. These boxed steel control arms replace factory rear control arms and work with axle torque to load the chassis, forcing the rear wheels downward for harder launches and improved 60-foot times.

Key Features:

• Boxed construction CNC machined from 1/8-inch wall USA mild steel tubing for exceptional strength
• 3-hole adjustable mounting design allows lift bar positioning at 2-inch, 2.75-inch, or 3.25-inch drop heights
• CNC laser-cut mounting brackets fabricated from 3/16-inch thick steel
• Greaseable polyurethane bushings with MIG-welded holders reduce deflection while maintaining street comfort
• Reinforced sway bar mounting holes with TIG-welded 1/8-inch steel sleeves maintain proper sway bar position
• Durable powder coat finish for corrosion resistance
• Grade 8 mounting hardware included
• Bolt-in installation requires no drilling or cutting (welding recommended for drag radials or slicks)

These lift bars are designed to correct lost geometry and instant center on lowered vehicles without affecting ride height. The adjustable mounting design allows fine-tuning of suspension geometry for optimal traction. For maximum rear suspension performance, UMI recommends pairing these lower control arms with adjustable upper control arms. Complete kit includes all mounting hardware and installation instructions.
