Bump Steer Gauge Billet Plate Universal

The Bump Steer Gauge Billet Plate Universal (model 52-79005) is a precision alignment tool designed for professional suspension technicians, chassis builders, and serious automotive enthusiasts who demand accuracy in wheel geometry setup. Bump steer—the change in toe angle as suspension compresses and extends—is a critical parameter that affects vehicle stability, tire wear, and handling predictability. This adjustable analog gauge eliminates guesswork by providing real-time measurement feedback during suspension tuning and diagnostic work.

Longacre's billet plate construction delivers the rigidity and repeatability required in high-precision automotive work, resisting deflection under measurement stress and maintaining calibration over extended use. The universal design accommodates both 5-bolt and wide-5 wheel patterns, making this gauge compatible with a broad range of vehicles—from street-driven imports and domestic platforms to vintage hot rods and competition builds. The analog readout provides instant visual reference without batteries or digital drift, allowing technicians to monitor suspension behavior across the full range of wheel travel with mechanical simplicity and proven durability.

This tool is essential for fabricators, suspension shops, and drag racers optimizing chassis geometry for traction and consistency, as well as road-course competitors fine-tuning handling balance. The adjustable stand design allows precise height and angle positioning on varied work surfaces, and the 22 x 5 x 22 inch footprint provides stable measurement geometry without excessive shop floor footprint. Setup requires mounting to the wheel hub via the 5-bolt or wide-5 pattern; the analog gauge then measures lateral wheel movement relative to the suspension centerline, revealing toe-change curves that indicate tie-rod geometry issues, ball-joint wear, or design opportunities for improved setup.
