Technical Details of Moog CC721 Coil Springs

The Moog CC721 coil spring set features a variable rate design, which means the spring rate increases as the spring compresses. This allows for a smoother ride during normal driving conditions and firmer support under heavier loads or rough terrain. Both front and rear springs share identical dimensions, including a relaxed length of 14.16 inches and a compressed length of 11.00 inches, ensuring balanced suspension performance. The wire diameter of 0.54 inches (13.70 mm) and a spring rate of 182 lbs per inch provide the necessary strength and flexibility for the Jeep Grand Cherokee's suspension system. The springs are finished in black for corrosion resistance and durability. The end types, tangential and pigtail, are designed to fit securely within the suspension mounts, maintaining proper alignment and function.
