Plate Bump Steer / Tow 5in x 5in

The Wehrs Machine Plate Bump Steer/Tow 5in x 5in (WM316-5X5) is a precision alignment plate engineered for vehicle suspension geometry setup and bump steer measurement on alignment racks. This single aluminum plate delivers the dimensional accuracy required for professional chassis tuning, allowing technicians to isolate suspension movement during compression travel and verify toe-in changes across the suspension stroke.

At 0.75 inches thick and machined from aluminum, the plate provides rigidity essential for repeatable measurements while remaining manageable in a service environment. The 5-inch x 5-inch footprint accommodates standard wheel hub geometry and integrates with typical alignment rig jigs and fixtures. Weighing 21.5 pounds, it maintains structural integrity under repeated suspension cycling and measurement loads without excessive mass that would compromise ease of handling during setup procedures.

This plate is essential for race teams, suspension shops, and serious enthusiasts performing bump steer testing on performance vehicles, street rods, and off-road chassis where suspension compliance affects steering response. Correct bump steer measurement prevents unwanted steering input during compression—a critical control point in suspension geometry optimization. Shops and tuners rely on Wehrs Machine alignment tooling for consistency across fleet work and competitive builds where suspension precision directly impacts vehicle control and driver confidence.

Wehrs Machine has built a reputation for precision measurement tooling across the automotive service and racing sector. The natural finish aluminum construction resists corrosion in typical shop environments, and the simple, robust design integrates with aftermarket and OEM alignment systems without modification. Single-plate configuration allows flexible setup for specific vehicle platforms and suspension geometries.
