For over thirty five years The Ultimate Suspension has set the standards by which all aftermarket 4WD suspensions are judged. Features detailed here are only a selection of the many incorporated in the innovative design which make all Ultimate Suspension systems true to our name.
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 then 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 provide you the assurance of outstanding performance and safety backed by The Ultimate Suspension's unique Life Time Warranty* (Conditions Apply).
Safety, comfort and performance through design - combining 35 years of experience in suspension integration with the highest grade quality materials, the latest in technological design and international standard manufacturing processes.
The ultimate choice of a fully integrated suspension system provides a selection of coils with individually matched and tuned shock absorbers to suit each specific application.
As suspension requirements are split into three categories, standard height heavy duty, raised height comfort, and raised height heavy duty. It is impractical to expect one spring or shock absorber design to provide optimum results.
The Ultimate Suspension system provides you the individual choice to suit your specific requirements.
Designed and manufactured in Australia to suit Australian conditions as well as earning valuable export dollars on the international markets.
