These Edelbrock Adjustable Panhard Rods complement Edelbrock's Lower Trailing Arms. The improved design resists unwanted flex and twisting, keeping the axle properly located under the chassis for improved cornering and drivability under all conditions. Edelbrock's Panhard Rods include Edelbrock's fluted, greasable, graphite/polyurethane bushings for a long trouble free life. CNC-machined, MIG-welded for a more precise axle retention and increased cornering control.
