J&M Race/Extreme Weight Jack Lower Control Arms; Red (99-04 Mustang, Excluding Cobra)Find parts that fit my vehicle

Unleash your Mustang’s full potential on the street, strip, or track. J&M Products’ Race/Extreme-Duty Rear Lower Control Arms are the ultimate upgrade for 1979–1998 & 1999–2004 Ford Mustangs, engineered to eliminate wheel hop and drastically improve traction and handling. These high-performance arms replace the flexible factory-stamped components and soft rubber bushings that cause unpredictable rear-end behavior under heavy loads.

Engineered for Extreme Performance

Unlike stock and standard aftermarket arms, J&M’s Race/Extreme-Duty series is built for vehicles with extremely high horsepower and aggressive launch scenarios, including drag racing and hard street launches.

• Zero-deflection spherical bearings: High-strength, robust spherical bearings with protective seals are used at both ends of each control arm. This design eliminates the flex and deflection common with rubber and urethane bushings, ensuring your axle stays planted and dramatically reducing wheel hop.

• Optimal suspension articulation: The spherical bearings still allow for the necessary, bind-free articulation of the rear suspension, preserving cornering predictability and chassis health. This is crucial for maintaining control while minimizing stress on your Mustang’s chassis torque boxes.

• Enhanced traction and stability: By preventing the axle’s fore-and-aft movement, these control arms ensure your rear tires apply power consistently and predictably, eliminating the “rear steer” effect that plagues stock and lesser aftermarket designs.

Built for Superior Durability and Strength

J&M Race/Extreme-Duty arms are constructed with exceptional materials and manufacturing processes to withstand maximum abuse.

• Robust construction: Made from large, 2-inch diameter round steel tubing, which offers superior strength in bending and torsion compared to square or rectangular tubing.
_x000D_
• Precision manufacturing: Built in the USA using advanced manufacturing techniques like laser-cut main tubes and sway bar plates, CNC-machined billet spring seats and bearing cups, and pulse welding (stronger than standard MIG welding) to ensure superior strength and durability.

• Correct fitment: Designed as a direct bolt-on replacement for all 1979–1998 & 1999–2004 solid-axle Mustangs. These arms feature correct-fitment spring perches and sway bar mounts, ensuring a seamless installation.

Why Choose the Race/Extreme-Duty Arms?

For high-horsepower builds or those that launch aggressively, standard urethane bushings can fail prematurely. The Race/Extreme-Duty arms’ heavy-duty spherical bearings are specifically engineered to endure the immense forces generated during hard launches on drag slicks or performance tires, ensuring maximum reliability when you need it most.
