Steeda 'Stop the Hop' Drag Ultimate Kit (555-2129-D-7G) - 2024-2026 Mustang Non-Brembo
Launch harder and eliminate wheel hop with the Steeda 'Stop the Hop' Drag Ultimate Kit for the 2024-2026 Ford Mustang. Designed specifically for S650 Mustang GT and EcoBoost models equipped with the factory non-Brembo brake package, this comprehensive IRS suspension package strengthens the rear suspension, minimizes deflection, and maximizes traction to help you achieve quicker 60-foot times and more consistent quarter-mile performance.
The factory independent rear suspension uses compliant rubber bushings that allow excessive movement under hard acceleration, leading to wheel hop and lost traction. Steeda's Drag Ultimate Kit addresses every major source of IRS deflection by reinforcing the subframe, aligning the rear cradle, upgrading critical suspension links, and replacing factory rubber bushings with precision-engineered performance components. The result is improved suspension geometry, greater chassis stability, and more efficient power transfer to the rear tires.
