Overview

The Ultra Racing Rear Lower Bar is a 4-point chassis brace designed to reduce chassis flex. It connects at the lower suspension mounting points to the vehicle chassis, lessening distortion under load, especially during hard cornering. This brace helps maintain accurate camber during aggressive driving.

Show original supplier description

The Ultra Racing 4-point Rear Lower Bar is engineered to significantly reduce chassis flex in the rear suspension system. By reinforcing the connection points between the lower wishbone and the vehicle chassis, this brace minimizes distortion and improves rigidity, particularly during demanding driving conditions like hard cornering. This enhanced stiffness helps maintain more accurate camber angles, leading to improved stability and handling. Constructed from a single piece of welded steel for maximum strength and durability, the bar features a powdercoated white finish. It installs directly to OEM mounting points using the included hardware, requiring no cutting or welding. Most installations can be completed in 30-60 minutes with basic hand tools. In such cases, minor modifications might be necessary. Ultra Racing offers a Limited Lifetime Warranty on all its products, covering defects in materials and workmanship.
