If your vehicle is wallowing in the turns and sagging, it may be time for new coil springs. MOOG coils springs are manufactured from heat treated alloy steel to resist sagging and given an enamel coating to resist corrosion. In addition, some springs come with urethane protective tubes. MOOG coil springs are available in constant rate design, variable rate design, and cargo coil design. Constant rate springs will restore ride, handling, and ride height to OE specs. Variable rate springs change resistance as they compress, becoming progressively stiffer, and are ideal for vehicles that carry heavy loads. Cargo coils provide additional load capacity, support, and stability, and are ideal for commercial vehicles and towing and camper packages.

As years passed and MOOG continued to innovate, the company became known for its ability to consistently develop “problem solving solutions.” Today, hundreds of innovations later, MOOG is recognized and respected throughout the automotive industry as The Problem Solver. It continues to earn that reputation by providing not only problem-solving parts, but award-winning technical support and training materials also.
