Lower Control Arm Checker

The WEHRS MACHINE Lower Control Arm Checker (WM477) is a precision aluminum fixture designed for accurate measurement and verification of lower control arm geometry on Chevelle and metric control arm applications. This specialized tool addresses a critical need in suspension setup and alignment work: confirming control arm dimensions and detecting wear, bending, or manufacturing variance before installation.

Constructed from aluminum for lightweight portability without sacrificing rigidity, the checker measures 26.5 inches in length and weighs 2.5 pounds—dimensions that allow precise checking of control arm bends, twists, and mounting point alignment. The fixture's design accommodates both original Chevelle geometry and metric control arm patterns, making it a versatile reference tool for suspension specialists and fabricators working across different platform architectures. Proper control arm verification prevents misalignment-induced tire wear, handling degradation, and suspension component premature failure.

This tool is essential for fabricators, restoration shops, and suspension specialists who need to validate control arm condition during assembly or repair. It's particularly valuable when sourcing used or reproduced control arms, where hidden bending or dimensional drift from specification can compromise the entire suspension system's geometry and performance. The WEHRS MACHINE Lower Control Arm Checker eliminates guesswork and provides objective measurement reference, ensuring suspension components meet specification before installation on customer or personal vehicles.

Each fixture comes as a single unit ready for immediate use. For shops running high-volume suspension work or offering detailed pre-assembly inspection services, this checker becomes a foundational diagnostic tool that justifies its cost through reduced comebacks and customer satisfaction tied to proper alignment from day one.
