EFS Suspension
Enhanced Four Wheel Drive Suspension
EFS Suspension from Superior Engineering is a quality driven product that has been proven in 4WD Competitions throughout Australia and pushed to the limits by 4X4 enthusiasts around the world. EFS suspension kits offer a complete integrated suspension package of springs, shocks and components that work together to provide quality on-road handling and greater off-road ability.
At Superior Engineering, we stock a wide range of EFS’ best suspension kits and suspension components, including shocks, leaf springs, and more. This collection also includes EFS Elite and Enforcer shocks, which have been carefully designed and manufactured to improve durability, responsiveness and comfort for you and your passengers.
EFS has designed and developed a high quality suspension system to combat Australia's harsh off road conditions. The EFS suspension range is under constant development and is put through the harshest tests with our sponsored competition vehicles. The dedicated EFS suspension R&D team have excelled in the fine tuning of shock absorbers, coil and leaf springs and components, with the development of the EFS Elite Range.
The EFS Shock Absorber will ensure controlled and consistent dampening and is based on a large body twin tube, low pressure nitrogen gas design. The experienced team at EFS have taken much care in designing and developing valve codes to ensure that the consumers expectations are met in all situations found when traversing the various road networks and remote areas of Australia. This is what makes EFS superior to many competitors.

EFS leaf springs are available in 30mm to 80mm raised heights with a slight increase in spring rates over the original equiptment.
Tapered Leaf Ends - To reduce the inter-leaf friction and to improve pressure distribution in the bearing area.
Bolt Clip Liners - To reduce noise and friction.
Inter-Leaf Graphite Coating - For further reduction of friction.
Shot Peened & Scragged Tested - To reduce stress and ensure longevity.
Leaf Inserts - For further reduction of friction.
Bolt Clips & Military Wraps - To prevent leaf spread and provide safety.
