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 is not just a Shock Absorber - EFS suspension kits offer a complete integrated suspension package of Springs, Shocks and Components that work together to give quality on-road handling characteristics and greater off-road ability.
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.
Shock absorber design hasn't changed much over the last 50 years. One thing has changed, 4WD enthusiasts know what they want and they look for products that have been developed to suit Australian conditions. That's why EFS shock absorbers have been rigorously tested in Australia. Don't be misled, this product is purpose built, and designed right here.
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 Suspension Coil Springs
Shot Peened - To stress relieve the outer surface of the Coil, so the Coil can operate under higher fatigue & repeated load conditions to ensure longevity.
Scragged for Quality Control - This is a process where the Coil is compressed beyond its yield point; this compression will set-up residual stresses and increase the elastic limit of the spring.
Powder Coated - To resist corrosion & for aesthetics.
EFS Coil Springs are manufactured under a strict quality control system with the use of quality Spring steel in accordance with ISO-9002.
EFS Springs are produced in a variety of raised heights, 30mm to 125mm & also a variety of spring rates to suit different applications - Towing, Load bearing accessories, Increased ride height & Competition.
EFS Suspension Leaf Springs
EFS Multi Leaf Springs from Superior Engineering are made from high quality Japanese grade SUP9 and SUP9A Alloyed Carbon spring steel.
Designed as a comfort Leaf Spring that incorporates special features, to give the driver a comfortable ride on road and increased control off road with increased articulation and clearance.
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.
EFS Suspension Torsion Bars
EFS Torsion Bars from Superior Engineering have increased spring rates of approx 25% to 30% over the standard OEM Torsion Bar. Just like Coil Springs and Leaf Springs, Torsion Bars fatigue and sag... so do torsion bars.
The EFS Torsion Bars will provide you with increased handling and response from your vehicle and compensate for the extra front weight of bull bars, winches and load bearing accessories.
Pre-stressed - To ensure strength, longevity and durability. Also an increased in spring rate to compensate for load bearing accessories.
EFS Torsion Bars are manufactured from XK-5160 High Carbon Alloy Steel to ensure strength and reliability.
