Stop the Hop Handling Ultimate Kit

The Steeda Stop the Hop Handling Ultimate Kit provides a robust foundation for improved traction and suspension compliance by addressing the movement of the factory IRS subframe. By utilizing CNC-machined delrin alignment dowels, billet 6061 aluminum bushing supports, and a chrome-moly steel support brace, the kit squares the subframe to the chassis and limits unwanted side-to-side, front-to-back, and vertical movement under hard acceleration or braking. Additionally, the inclusion of upgraded rear toe links, billet aluminum vertical links with urethane bushings, and adjustable differential bushing inserts further reduces deflection and improves control over the rear end. Installation requires no permanent modifications to the vehicle and features stainless steel hardware for long-term durability. It does not fit 2024+ Mustang models equipped with Brembo brakes and is not compatible with the GT500. Users should be advised that the installation of the differential bushing system may increase noise, vibration, and harshness (NVH), potentially leading to increased transfer of gear whine in some Super 8.8 IRS differentials.
