• Enhanced stability: Air springs offer excellent stability, especially in situations where the vehicle is carrying uneven loads. The ability to adjust the air pressure in each spring ensures that the vehicle remains level and well-balanced, improving overall safety and handling.

Progressive Springs

Progressive springs, also referred to as variable-rate springs, have gained popularity due to their unique design. Unlike traditional linear springs, which provide a consistent level of stiffness throughout the compression and rebound process, progressive springs offer a varying level of resistance. They are designed to become stiffer as they compress, providing a comfortable ride while still maintaining stability during aggressive driving conditions.

Progressive springs offer the following advantages:

• Improved ride quality: Progressive springs deliver a smoother ride compared to linear springs, especially on rough or uneven road surfaces. The varying levels of resistance allow for better shock absorption and improved control over the vehicle’s suspension.
• Enhanced handling: The progressive nature of these springs enhances the vehicle’s handling capabilities, particularly during aggressive driving maneuvers. The stiffer compression rate provides better stability and responsiveness, allowing drivers to maintain control and maneuver the vehicle with ease.
• Reduced body roll: Progressive springs help minimize body roll, which is the lateral movement experienced during cornering. By providing increased resistance as the springs compress, they help stabilize the vehicle’s body, resulting in improved cornering performance and reduced body lean.
