Description & Feature
Manzo Performance Lowering Springs are built from cold-wound steel, one of the strongest and most reliable materials available for suspension components. Featuring high tensile strength and a phosphate powder-coated finish, these springs deliver excellent durability, corrosion resistance, and long-lasting performance without premature sagging.
Designed to deliver race-inspired handling without sacrificing daily comfort, these springs offer a balanced blend of performance and ride quality. Carefully matched spring rates provide precise handling, improved response, and enhanced control, all while maintaining a smooth and compliant ride.
These springs deliver a noticeable drop in ride height, improving your vehicle’s stance and lowering its center of gravity for better stability and cornering performance. Despite the performance-focused design, they maintain sufficient ground clearance to prevent bottoming out, making them ideal for street-driven vehicles.
Note: Spring rates and drop amounts may vary depending on vehicle application and chassis load.
