FAQ

Shape factor and durometer (density) are the two criteria that most effect spring rates. By varying durometer and shape factor, a wide range of spring curves can be achieved.
Drivetech SumoSprings have been designed to assist in levelling your vehicle and reducing body roll when carrying load. You should never exceed the vehicles gross vehicle mass rating.
Yes. All Drivetech SumoSprings come with an exploded view schematic and detailed fitting instructions.
The variable load Drivetech SumoSpring has been designed with the male guide section of the spring mounted below the female section of the spring. This reduces the risk of any foreign matter becoming lodged between the two spring sections.
Due to the nature of the Drivetech SumoSprings microcellular polyurethane material, it is highly unlikely that any part of your Drivetech SumoSprings would dislodge.
Your Drivetech SumoSprings have been designed as a load levelling device. You should never exceed your gross vehicle mass rating. By correctly positioning your load and never exceeding the GVM rating, your risk of chassis fatigue will be very low.
Never. Drivetech SumoSprings are 100% maintenance free. Simply fit it and forget it.
No. Drivetech SumoSprings are made from a microcellular polyurethane material. As no air is present in the springs, you could literally push a screw driver through your Drivetech SumoSpring and not affect its performance or load carrying ability.
Spacer blocks have been designed in 1 inch and 2 inch sizes to allow vehicles that have had a suspension lift to benefit from Drivetech SumoSprings.
Drivetech SumoSprings have developed a revolutionary variable load spring. This innovatively designed spring separates to allow unrestricted suspension articulation.
Drivetech SumoSprings have been designed to fit into existing air bag brackets. If you are tired of maintaining your existing air bags or have a failure and never want to be stuck again, simply remove your existing airbag and fit a set of Drivetech SumoSprings.
By assisting in the load carrying capability of your vehicle, Drivetech SumoSprings progressively take up your load and reduce the level of stress and pressure put on your leaf springs.
Drivetech SumoSprings can be fitted to original equipment leaf springs or vehicles that have had suspension lifts of up to 2 inches.
Drivetech SumoSprings microcellular polyurethane springs have been specially designed to offer little resistance when unloaded. The progressive rate of the spring activates when load is applied. This means whether loaded or unloaded, your vehicles rebound resilience is increased making for a stable, smooth and level ride.
Drivetech SumoSprings have been tried and tested in temperatures from -30°C to +80°C with no deterioration in performance.
Drivetech SumoSprings have the ability to stretch to 30% of their unloaded height with full memory rebound. Based on Australian vehicle testing, most standard suspension travel distance is within this range.
Drivetech SumoSprings are backed by a 2 year / 40,000km warranty.
Drivetech SumoSprings have been tested in Australia over the two years without detriment or signs of deterioration. Market intelligence indicates that Drivetech SumoSprings will last longer than an airbag.
Drivetech 4x4’s Fuel Manager is a unique pre-filter to the Original Equipment filter, suitable for use on any diesel engine to effectively protect diesel injection components from water, humidity, dust, grime, algae, acids and other contaminants.
Modern diesel engines feature common rail fuel injection systems. While these offer increased precision, they operate at very high pressure. Hence if any dust, dirt or water finds its way into the system, it can cause significant damage. “Because such fine amounts of fuel are being injected through a common rail system at very high pressure, if contaminants get into the system they can cause thousands of dollars worth of repairs,” says Motospecs Category Manager, Ben Lavis. It’s surprising how easy it is for small particles to enter a diesel engine’s fuel injection system. Off road situations, as well as mining and rural locations are some of the more obvious instances where dust, dirt or water might find its way into the fuel injection system, but it does happen as a result of ordinary metropolitan driving or filling up with contaminated fuel. “It’s not often that you’ll pick up bad diesel fuel, but it does happen, surprisingly,” says Ben. “Particularly if you buy fuel when the service station’s tanks are almost empty, there is a chance the fuel could include water particles that have built up as a result of condensation on the tank. It’s the same in fleet or mining situations where fuel is stored on site where it harbours moisture.” Even the smallest amount of water in the fuel injection system can result in the need for a complete re-build – a costly and inconvenient exercise
Fuel Manager separates 99% of contaminants before they reach the Original Equipment filter, thus providing an extra level of protection and ensuring the fuel injection system remains free of harmful particles. Fuel Manager features a long life filter media that has been heat and chemically treated for maximum durability and acid resistance. “As well as dirt, grime, algae and dust, a big plus with Fuel Manager is that it separates water from fuel – most Original Equipment filters don’t have this capability,” says Ben. “Another feature is Fuel Manager’s multi-port head which allows mounting in any place and in any configuration.”
Drivetech 4x4 Fuel Manager kits are vehicle-specific and come with everything you need to easily install Fuel Manager in the engine bay without having to modify any existing vehicle components. The kits include: • Drivetech 4x4 Fuel Manager pre-filter unit • Vehicle-specific, high grade stainless steel mounting bracket • Step-by-step installation instructions • Vehicle-specific fuel line hose • Polycarbonate bowl. All components are tightened and removed by hand – there’s no need for filter tools when installing Fuel Manager.
Drivetech 4x4 Fuel Manager suits all diesel engines from 50 to 350 horse power (37 to 261 kW) with a maximum fuel operating pressure of 60 p.s.i. As well as passenger and 4WD vehicles, Fuel Manager is also suitable for diesel tractors, diesel motors etc.
Drivetech 4x4 Fuel Manager optional extras include: • Water Sensor Kit – signals that water has accumulated in the filter and must be drained. • Replacement Filter Elements – available in 30, 5 and 2 micron. • Hand Primer Pump – for quickly purging air that has entered the lines during an element change or draining of the water and residue catch.
