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.

SHOCK ABSORBERS
1. Polyurethane bushes are used on all applications for positive location and increased longevity and resilience.
2. Multi-lip piston shaft seals are used on all applications to keep the containments out and retain gas pressure and hydraulic fluid.
3. Induction hardened, high quality chrome piston shaft of 15mm or 16mms ensures the strength, durability and rust resistance required to prevent damage to the shaft and guide seal.
4. Pressure tube/bore size of 35mm to 36mm offers optimum piston displacement for control in all environments.
5. The 50mm large body twin tube construction of the EFS shock absorber guarantees an expanded oil reservoir for better cooling due to the larger surface area.
6. Most EFS shock absorbers are pressurized with low pressure Nitrogen gas to prevent aeration and cavitation for more consistent dampening control.
7. Steel shrouds are used on all applications where space permits. Other locations are catered for with an optional polyurethane dust boot to deflect debris from piston shaft and guide seal.
8. Velocity sensitive piston adjusts to provide optimum control in all situations.
9. Variable temperature Hydraulic fluid is used to ensure consistent fluid viscosity at all temperature ranges.
10. Velocity sensitive compression valve for consistent fluid control on compression and rebound strokes.
11. To ensure the integrity of the shock absorber all EFS shocks are supplementary welded on all mountings where required for added strength.
12. Mechanical and hydraulic top out stops used on most applications. To prevent internal damage during extreme off-road work.
