▶ Vehicle Fitments
The AST 40mm Lowering Springs for the Mercedes-Benz SL-Class W107R are high-performance suspension components designed to improve handling and aesthetics. Crafted from premium high tensile chromium-silicone wire, these springs are selected for their strength and consistency. Each spring undergoes a meticulous manufacturing process, including cold winding, heat treatment to enhance hardness and reduce internal stresses, and shot peening for increased fatigue life. The phosphate coating and powder coating finish ensure durability and resistance to corrosion, allowing these springs to outlast the vehicle itself. Featuring progressive spring rates, they provide a smooth ride while lowering the vehicle's stance by approximately 40mm, enhancing both stability and visual appeal.
These springs are specifically engineered for 1972-1982 Mercedes-Benz SL-Class W107R models, fitting a range of chassis and engine configurations within this period. They serve as direct replacement upgrades for the factory springs, offering improved handling characteristics suitable for street and spirited driving. Installation is straightforward, designed as bolt-on components that integrate seamlessly with existing suspension setups. The kit includes the necessary springs, with no additional components required. Ideal for enthusiasts seeking a lowered stance and enhanced performance, these AST springs deliver a combination of durability, comfort, and improved vehicle dynamics.
