CorteX Xtreme-Grip Torque Arm System (1979–2004 Mustang)

Maximize Rear Grip & Performance

The CorteX Xtreme-Grip™ Torque Arm System is a game-changing rear suspension upgrade for 1979–2004 Mustangs, designed to dramatically improve traction, stability, and overall performance. Whether you're launching hard at the drag strip or pushing limits on a road course, this system delivers unmatched rear grip without sacrificing cornering ability.

Transform Your Suspension Geometry

By replacing the factory 3-link setup and eliminating the upper control arm, the torque arm system redefines rear suspension geometry. It allows for significantly increased anti-squat while maintaining proper roll steer—something traditional 3- or 4-link setups struggle to achieve.

Perfect for Lowered Mustangs

Lowering your Mustang can negatively affect rear suspension geometry, reducing traction under acceleration. The CorteX Torque Arm corrects these issues by optimizing anti-squat and anti-lift characteristics, restoring and even exceeding factory performance levels.

Improved Traction & Power Delivery

The torque arm design ensures more even loading of the rear tires, maximizing traction and allowing your Mustang to put power down more effectively—especially in high-horsepower applications.

Reduced Front-End Dive Under Braking

By relocating axle forces closer to the vehicle’s center of gravity, this system significantly reduces front-end dive during braking. The result is a more stable chassis and increased driver confidence under hard braking conditions.

Race-Proven Design for Street & Track

Designed for both street and competition use, the CorteX Torque Arm provides improved acceleration, braking stability, and corner exit performance. The higher the horsepower, the greater the benefit this system delivers.

Why Choose a Torque Arm?

Traditional suspension setups rely on spring compression to transfer weight, delaying traction under acceleration. The CorteX Torque Arm allows instant weight transfer to the rear tires, improving launch consistency and overall performance while maintaining proper cornering dynamics.
