Bump Steer Spacer Kit

The ALLSTAR PERFORMANCE Bump Steer Spacer Kit (ALL 18601) is a precision alignment tool designed to eliminate bump steer and steering geometry inconsistencies in race-tuned suspension systems. This kit contains steel spacers ranging from 0.030 to 0.500 inches in thickness, allowing adjustable correction of tie-rod height relative to the steering arm pivot point—a critical factor in maintaining straight-line stability during aggressive acceleration or braking.

Bump steer occurs when suspension vertical travel causes unintended steering input, compromising vehicle control and predictability. By shimming the tie-rod mounting point, this spacer kit corrects the instant center geometry and ensures the steering axis remains neutral through suspension articulation. The included zinc oxide-plated steel spacers resist corrosion in harsh track environments and deliver the exact incremental adjustments needed for fine-tuned geometry correction. The range from 0.030 to 0.500 inches allows builders to dial in precise tie-rod height on both front and rear suspensions, accommodating various chassis platforms and suspension designs.

This kit is essential for drag racing, circle track, road racing, and performance street applications where suspension tuning directly impacts steering response and safety. Drivers and suspension engineers rely on bump steer correction kits to achieve consistent handling characteristics across the full range of suspension travel. Whether you're building a competition car, installing an aftermarket suspension system, or dialing in a street-performance platform, the ALLSTAR PERFORMANCE spacer kit provides the adjustment range and material quality needed for professional-level results.

ALLSTAR PERFORMANCE is recognized in the race community for manufacturing precision suspension components and alignment tools that support both OEM and custom builds. This spacer kit integrates seamlessly with most tie-rod ends and steering arms, making it a standard choice for fabricators and race teams focused on geometry optimization.
