J&M Products Rear Weight Jack Adjustable Lower Control Arms (23960-B - Black Powder Coat) - 1999-2004 Ford Mustang
Achieve professional-grade suspension tuning for your 1999-2004 Mustang with J&M Products' rear weight jack lower control arms. Designed specifically for New Edge Mustangs with solid rear axles, these arms provide the ability to fine-tune rear weight transfer and ride height via a built-in spring perch weight jack. By replacing the flex-prone factory hardware with high-strength, pulse-welded construction, you eliminate the unpredictable handling and inconsistent launches caused by chassis twist, ensuring your Mustang plants power to the pavement reliably on every run.
Engineered and manufactured in the USA, these weight jack arms utilize a street-smart hybrid bushing strategy: a 3-piece Poly-Ball bushing on the chassis side for bind-free articulation, and a heavy-duty chrome-moly spherical bearing on the axle side to eliminate deflection. This combination provides the rigidity required for high-performance track use while maintaining the smoothness needed for aggressive street driving. Finished in a durable black powder coat for superior corrosion resistance and backed by a lifetime warranty for the original owner, these direct bolt-on arms are the ultimate foundation for your performance suspension setup.
