Bump Steer Spacer .500

The U-B Machine Bump Steer Spacer .500 is a precision-machined suspension alignment component designed to correct bump steer conditions in vehicles with modified suspension geometry. Built from steel with a zinc oxide protective finish, this 0.500-inch thick spacer addresses the geometric changes that occur when suspension ride height is altered, preventing the front toe angle from shifting during vertical wheel travel—a critical concern for off-road platforms, lifted trucks, and vehicles running upgraded suspension packages.

Bump steer manifests as unpredictable steering feel during suspension articulation and can compromise vehicle control on uneven terrain or during aggressive maneuvering. The 0.500-inch thickness of this spacer corrects the steering axis geometry by adjusting the relationship between the tie rod mounting point and the ball joint, restoring the neutral toe curve that factory suspension was engineered to maintain. The zinc oxide finish provides corrosion resistance in salt-air and moisture-heavy environments typical of coastal operations and wet-weather deployments. At 0.05 lbs and compact dimensions (2.1 x 0.65 x 2.9 inches), the spacer integrates cleanly into existing suspension assemblies without requiring frame modifications or cutting.

This component is essential for operators and enthusiasts running lifted suspensions, long-travel kits, or custom ride-height modifications on tactical support vehicles, overland platforms, and off-road recovery rigs. Installation requires proper alignment equipment and suspension knowledge; incorrect spacer thickness or placement will worsen steering geometry rather than correct it. The U-B Machine part number 44-0320 is precision-manufactured to tight tolerances, ensuring consistent performance across repeated suspension cycles and unforgiving terrain.
