This adjustable tubular panhard bar replaces the stock bar on 58-64 GM B-Body vehicles, enhancing rear-end stability and alignment. It allows on-car adjustments to center the rear end by simply loosening two jam nuts, providing extra tire clearance and proper alignment. The bar features new grease-able polyurethane bushings and requires no modifications for installation, which can be completed in under 30 minutes with basic tools. Constructed from 1.000" x 0.156" DOM Mild Steel Tubing and fully TIG welded, it includes a 4140 Heat Treated Adjuster for durability and a powder coat finish. Note: Not suitable for wagons—verify length before ordering. Center-to-center distance is 31-3/8", adjustable between 30-7/8" and 31-7/8".
