Technical Specifications and Design Details

The Moog CC670 coil spring set features a variable rate design, which means the spring rate increases progressively as the spring compresses. This allows for a smoother ride under normal driving conditions and firmer support during heavy loads or aggressive maneuvers. Both front and rear springs share identical dimensions, including a relaxed length of 15.75 inches and a compressed length of 9.00 inches, ensuring balanced suspension performance. The black finish provides corrosion resistance, while the 0.56-inch wire diameter contributes to the spring's structural integrity. Pigtail ends on both sides facilitate proper seating within the suspension assembly.
