Kit Contains: Front Shock Absorbers 36-5604 35mm Bore Elite Touring Shock Rear Shock Absorbers 36-5426 35mm Bore Elite Touring Shock About EFS 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 SHOCK ABSORBERS DMC-T - Dynamic Motion Control Technology 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 terms 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. EFS Elite Shock Absorbers 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.
