The Ratcheting Bump Steer Stick by WEHRS MACHINE is a precision suspension-tuning tool designed for serious automotive enthusiasts and professional mechanics working on high-performance vehicles. Bump steer—unwanted toe-in changes during suspension compression—is a critical handling issue that degrades tire grip, increases wear, and compromises steering response, especially in lowered or modified chassis.
This tool allows you to diagnose and adjust bump steer with accuracy that would be impossible using eyeball methods, making it indispensable for road racing, autocross, and street performance builds where suspension geometry matters. The ratcheting design enables smooth, repeatable measurement as suspension moves through its full travel arc, translating vertical wheel motion into precise angular readings that reveal tie-rod-angle-induced toe changes.
Constructed with durable materials and engineering tolerances typical of WEHRS MACHINE's reputation, this tool isolates bump steer from ride height, allowing you to optimize draglink or tie-rod geometry without guesswork. The 15.8-inch length accommodates most passenger and performance vehicle suspension layouts, while the compact 3.6 x 1.9-inch profile ensures easy access in tight engine bays and suspension pockets where traditional measurement devices fail.
