Enhanced 4WD Suspension is a quality driven product that has been proven in 4WD competitions throughout Australia & pushed to the limits by 4WD enthusiasts around the world. EFS Suspension is not just a Shock Absorber but a complete integrated suspension package of Springs, Shocks & Components that work together to give quality on-road handling characteristics & greater off road ability.
EFS has designed & developed a high quality suspension system to combat Australia's harsh off road conditions. The EFS range is under constant development & is put through the harshest tests with our sponsored competition vehicles. The dedicated EFS research and development team have excelled in the fine tuning of shock absorbers, coil & leaf springs and components, with the development of the EFS Elite range.
The EFS engineers spend countless hours at the EFS Shock Absorber Dynamometer Facility, where they fine tune the internal shock absorber valving to suit each make and model of vehicle. What this means for you the customer, is that you have a product that gives you on road performance and off-road excellence. "Because leaf and coil suspensions create different ride characteristics, the EFS shock absorber has been designed to suit each individual application". EFS R&D Team EFS stand behind their product with a 3 year / 100,000 km Warranty
The EFS Elite Shock Absorber Range is developed for the 4wd owner who only pursues the best for their 4wd. EFS is built with high quality Internal & external components combined together to give you excellent performance and longevity. EFS shock absorbers are vehicle & height specific with valving developed to suit each vehicle. "Not a one shock suits all approach"
51mm - 60mm External Tube - Greater oil capacity to keep the valve at a lower operating temperature
Low Pressure Nitrogen Gas - Prevent the oil from cavitating (foaming)
Long Travel Design - Maximises wheel articulation
35mm Piston, Twin Tube Construction - Increased control of the spring during rebound and compression cycles
16mm Quality Hardened Chromed Piston Rod Longer service life, and greater lateral strength
1.5mm Outer & Inner Wall Thickness Greater durability and strength
Dynamic Motion Control Valve - Adjusts to different road & off road conditions
Polyurethane and rubber bushes – HI quality elastomer and rubber mounting bushes to suit specific applications
EFS shock absorbers are vehicle & height specific with valving codes developed to suit each vehicle. "Not a one shock suits all approach" .
EFS Enforcer is designed for the price conscious 4wd enthusiasts, who need a shock absorber that gets the job done. 51mm External Tube -For greater oil capacity & to keep the valve at a lower operating temperature
Low Pressure Nitrogen Gas -To prevent the oil from cavitation (foaming)
Long Travel Design -To maximise wheel travel when a vehicle is raised and increase articulation
32mm Piston, Twin Tube Construction - Greater control of the spring during the rebound and compression cycles
15mm Quality Hardened Chromed Piston Rod -Increased durability
1.2mm Outer and Inner Wall Thickness -For greater durability and strength
Dynamic Motion Control Technology - Adjusts to different road and off road conditions
High Quality Internal & External Components - To prevent fade under harsh conditions and long life poly bushes for durability
The EFS XTR Shock Absorber Range is developed specifically for the Out-back off-road Tourer, with a heavily laden 4wd. It is Improved with increased oil capacities to reduce operating temperatures and incorporates a highly robust construction to take on the worst Australian Out-back roads. EFS XTR shock absorber are designed & developed to suit each vehicle and are not a one shock suits all approach. They are constructed from high quality internal and external components to meet the demands of the modern 4wd.
64mm External Tube - Greater oil capacity to keep the valve at a lower operating temperatureLow Pressure Nitrogen Gas - Helps prevent the oil from cavitating (foaming)
Long Travel Design - Maximises wheel articulation
40mm Piston, Twin Tube Construction - Increased control of the spring during the rebound and compression cycles
20mm Quality Hardened Chromed Piston Rod - Longer service life, and greater lateral strength
2 mm Outer & Inner Wall Thickness - Greater durability and strength
Dynamic Motion Control Valve - Adjusts to different road & off road conditions Vehicle & Height Specific Valving
Mounting bushes – EFS use long life polyurethane & rubber bushes dependant on application
The EFS X-Treme Shock Absorber has taken over three years to develop and test. During this period, it's had countless trips along unsealed corrugated roads, highly strenuous technical off-road situations and has seen many laps of 4wd race tracks in competition vehicles. During this period the X-Treme has exceeded our expectations and has been pushed beyond the boundaries that a normal 4wd shock absorber can endure.

DMC-T is a new advancement in shock absorber technology developed by the EFS Research and Development Team here in Australia. Over the past few years EFS have been pushing the boundaries of shock development & refinement to give you a shock that increases the control of your 4wd whilst maintaining positive traction to the contact surface. This new piston valve technology reacts within one hundredth of a second giving you 'on the fly' automatic adjustment of your shock absorbers which keeps you in control.
In a more simple term this valving system will negate the use of externally adjustable shocks because this technology adjusts automatically while you are driving to suit the driving conditions. During slow, off camber, off-road situations the EFS shock will allow your vehicle's suspension to move in a more relaxed state allowing for greater articulation and off-road control. And during high speed situations eg.gravel roads and outback corrugations the valving tightens up with the speed of the fluid passing through the valve inside
the shock, giving you added control and safety.
The complete current range of EFS Shock Absorbers and Struts have now been enhanced with DMC Technology to give you piece of mind and confidence when you next take on your 4wd adventure.
