Bump Steer Spacer .300

The U-B Machine Bump Steer Spacer .300 is a precision steel shim designed to correct bump steer and geometry issues in high-performance suspension systems. Measuring 0.300 inches in thickness, this spacer fine-tunes steering behavior under load, a critical adjustment for vehicles running aggressive alignment settings or modified suspension packages where factory geometry has been altered. The zinc oxide finish provides corrosion resistance in demanding field conditions.

The .300-inch thickness specification allows for granular incremental adjustments between larger or smaller spacer options, giving technicians the precision needed to dial in consistent steering response across varying load states. Steel construction ensures dimensional stability and repeatable performance under the dynamic stresses of suspension articulation. The compact 1.85 x 0.45 x 2.95 inch footprint makes installation accessible in tight chassis environments. At 0.03 lbs, weight penalty is negligible, even when multiple spacers are used in a complete suspension tuning package.

This spacer is essential for off-road enthusiasts, suspension builders, and fabricators addressing bump steer symptoms in lifted trucks, rock crawlers, and track-oriented vehicles. Common applications include correcting steering wander caused by tie-rod geometry changes after suspension lift installation, tuning vehicles with custom control arm geometry, and dialing out pull or inconsistent response during articulation. Mechanics and technicians building or modifying suspension systems rely on properly-sized spacer kits to achieve predictable steering feel across the full range of suspension travel.

The .300-inch thickness sits in the mid-range of typical spacer increments, making it a standard reference point when assembling correction packages. U-B Machine components are widely recognized in suspension fabrication shops and high-performance rebuild facilities for dimensional accuracy and finish durability. SKU UBM44-0315 is a single-unit spacer; purchase additional pieces if your alignment correction strategy requires stacking multiple thicknesses or adjusting at multiple attachment points.

Before installation, verify suspension geometry changes and measure tie-rod angle relative to the steering axis to confirm the correct spacer thickness needed. Proper bump steer correction improves steering stability, reduces driver fatigue on technical terrain, and protects tie-rod ends and steering components from accelerated wear caused by misalignment during suspension movement.
