Reinforce Your G-Body's Rear Control Arm Mounts

The UMI Performance Control Arm Reinforcements are engineered to provide critical support to the rear upper and lower front control arm mounts on your 1978-1988 GM G-Body. As you increase your vehicle's power, the stock control arm mounts become susceptible to bending and even breaking. These robust reinforcements tie the upper and lower mounts together, significantly increasing strength and improving driving performance.

Engineered for Superior Fit and Strength

  • Durable Construction: Manufactured from high-strength DOM steel for maximum durability.
  • TIG Welded: Precision TIG welding ensures a strong and clean finish.
  • Contoured Design: Bent to precisely contour the vehicle's floor, eliminating the need for floor modifications or denting for a perfect fit.
  • Adjustable Fitment: Features adjustment capabilities to ensure a perfect installation on all 1978-1988 G-Body models.
  • Complete Installation Kit: Includes new longer Grade 8 bolts, lock nuts, and washers for a straightforward 100% bolt-in installation.

Don't let weak mounting points hold back your G-Body's performance. These reinforcements are essential for any performance-oriented build, ensuring your suspension components remain securely in place under stress. Experience enhanced stability and confidence on the street or track.

Upgrade your suspension with UMI Performance's reliable and expertly crafted Control Arm Reinforcements, available at GGCRACING.
