Xtreme-Grip Torque Arm System

Vehicles: Ford Mustang, Cougar Vintage(1964 – 1970)

The Xtreme-Grip Torque Arm System is a rear suspension component that delivers unsurpassed corner exit and straight-line rear grip without sacrificing cornering ability. You can also expect a significant decrease in front-end dive under braking since the rear axle rotational loads are now applied much closer to the center of gravity. These improvements are accomplished by changing the anti-squat and anti-lift geometry of the rear suspension.

Why Lowered Cars Need a Torque Arm

When a mustang is lowered from the factory ride height the rear suspension geometry is compromised reducing rear grip under acceleration. Relocating the lower control arms pivots on the axle is a step in the right direction, however, more improvement is possible. Our torque arm system allows significantly more anti-squat to be added to your mustang than with a 3 or 4 link design while still having correct rear axle roll steer.

Increase Traction Power

With a CorteX Torque Arm design, the rear tires are loaded more evenly than a 3-link design further maximizing traction.


  • Exhaust modification is required.
  • Subframe connectors are required.
