Get improved acceleration and handling with new Scott Drake Performance Under-Ride Traction bars for 64-66 Mustangs. These traction bars work to eliminate axle wrap and wheel hop on high performance applications. They have robust features like heavy-wall tubular bars with cast ends and 4-bolt cast axle mount brackets to help control rear axle movement. Scott Drake traction bars are made to handle more power with super strong .187 wall tubing that is twice the thickness of the competition. Each kit is finished in a durable semi-gloss black powder coating for a lasting performance and good looks. Rubber bushings, alignment spacers and zinc plated grade 8 hardware are included. Like all Scott Drake products, these are backed by the Scott Drake 100% satisfaction guarantee. Note: Welding required for installation.
