The Ultimate Leaf Spring is a fully staged progressively laminated leaf spring.
This means that the length of each spring is proportioned to the length of the proceeding leaf, improving the characteristic of the spring.
SUP 9A grade spring steel is used exclusively, greatly increasing elasticity and memory as well as giving longer life and greater safety.
Each Ultimate leaf is treated in computer controlled furnaces giving precise heat control. This precision is required because high grade steel is less tolerant to variation in temperature (during manufacturing) than commonly used lower grade steels. The fully assembled springs are then subjected to a final test to ensure all leaves are seated and working as an effective unit. The test involves more than 800 deflections under extreme pressures.
Ultimate leaf springs are designed in a range for each vehicle. This provides a choice of spring to suit different vehicle loading and driver requirements. Springs are cambered to accommodate different loadings on the driver and passenger side of the vehicle. Final quality control inspectors mark spring indicating whether the camber is at the upper or lower level of its tolerance. This allows matched sets of springs and can be fine tuned for additional unequal vehicle loading.
Spring rates are matched with appropriate shock absorbers from the “Ultimate” range according to the specific vehicle application.
The System materials, design and manufacturing techniques which are “The Ultimate” leaf spring give you the assurance of performance and safety backed by The Ultimate Suspension's unique Life Time Warranty (Conditions Apply).
