EFS Elite Shock Absorbers

EFS most popular selling 4WD shock absorber. Premium construction, super long warranty and suitable for many applications.

* 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 Coil Springs

EFS Coil Springs are produced in a variety of raised heights, from standard to 125mm & also a variety of spring rates to suit different applications - towing, load bearing, ride height & competition.

* 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 & to protect the spring steel from minor damage.

EFS Leaf Springs

EFS Multi-Leaf Springs are made from high quality Japanese grade SUP9 & SUP9A Alloyed Carbon spring steel.

* Tapered Leaf Ends - To reduce the inter-leaf friction & to improve pressure distribution in the load bearing area.
* Bolt Clip Liners - To reduce noise & friction.
* Inter-Leaf Graphite Coating - For further reduction of friction.
* Shot Peened & Scragged Tested - To reduce stress & ensure longevity.
* Leaf Inserts Pads - For further reduction of friction.
* Bolt Clips & Military Wraps - To prevent leaf spread & provide safety.

EFS U-BOLTS

Powder coasted for protection against corrosion & made from quality carbon steels with rolled threads to increase strength, due to a uniform grain finish.Deep nuts are supplied for safety & strength with flat washers to provide a smooth contact surface area to reduce plate friction.EFS have a vast variety of U-bolts on offer for most Makes and Models of 4wd's. We also can custom bend U-Bolts to order.

EFS PINS & SHACKLES

Engineered to be stronger than the original equipment & greaseable for ease of service. The EFS Pins & shackles are made from medium & high grade carbon steels then case hardened & gold cadmium plated or black oxided for increased strength & corrosion protection EFS offers standard replacements and a small range of anti-inversion std and extended shackles.

* Engineered with increased strengthGreaseable for ease of maintenance
* Case hardened & gold cadmium plated
* Extended & standard anti-inversion shackles
* 3 year / 100, 000 km warranty

EFS POLYURETHANE BUSHES

EFS Polyurethane Bushes are made from high quality elastomers which gives the EFS Polyurethane Bush a high isolating strength & durable.

EFS poly bushes have an elastomer rating of 80 Duro to give improved suppleness & grease channels for increased distribution of lubrication.properties.
