The complete strut assembly manufactured by Moog is engineered to increase vehicle dynamics. It gives a smoother ride and can be installed easily. For long life and greater performance, the struts are made with many improvements, which also include a triple piston rod seal that offers dual protection to an enhanced main seal, resulting in a longer life. MOOG's micro-cellular polyurethane Jounce bumper absorbs road impacts and reduces noise for smoother, quieter driving. The provided coil spring is coated to resist corrosion for consistent long-term performance. The piston rod has an outer wiper seal, which cleans the piston rod, preventing contaminants from entering the main seal.
