Frequently Asked Questions
Will an EFS suspension kit improve off-road performance?
Yes, EFS suspension kits are specifically designed to enhance off-road capability. The upgraded springs and shocks offer better articulation, improved ground clearance, and greater resistance to bottoming out on uneven terrain. This means your 4WD can maintain traction and control over rocks, ruts, and soft ground. These kits also help distribute weight more evenly, which is especially important when carrying gear or accessories like roof racks or long-range tanks. While not a substitute for driver skill, a good suspension system can make a noticeable difference in comfort and confidence while off-roading. It's a practical upgrade for any touring or off-road setup.
Are EFS suspension kits legal in Australia?
Yes, EFS suspension kits are legal in Australia when fitted according to local road authority guidelines. Most kits are engineered within the legal lift limits, typically up to 50mm, and use components that meet Australian Design Rules (ADR). To stay compliant, it’s important to have the kit professionally installed and ensure any required certifications, like engineering sign-offs, are completed — especially for modified or lifted vehicles. If you're upgrading for towing or carrying heavier loads, you may also need to consider a GVM upgrade. A licensed fitter can walk you through the process to make sure your suspension upgrade is fully road legal.
Do I need to realign my vehicle after fitting a suspension kit?
Yes, a wheel alignment is essential after installing a suspension kit. Lifting or altering your suspension can change the angles of your wheels and steering components, which affects handling, tyre wear, and overall safety. A professional alignment ensures everything tracks properly and that your tyres contact the road as they should. Many installers include alignment as part of the fitting service, but it’s important to ask. Ongoing maintenance, including periodic alignments and suspension checks, helps your system perform better and last longer. Keeping everything in spec also ensures you stay road legal and avoid extra wear on tyres or steering parts.
EFS Suspension Product Range
EFS offers a complete suspension range designed to improve comfort, control and strength across a wide range of vehicles. These products are built for touring, towing and off-road driving. The lineup includes coil springs, leaf springs, heavy-duty shock absorbers, airbag kits and mounting hardware. Each part is engineered to handle rough tracks, added load and tough conditions without compromising ride quality.
EFS also provides custom setups for specific vehicles or applications. Whether your goal is better balance under load or increased ground clearance, the right combination can make a big difference. We’ll walk you through the options and help you choose the most suitable components for your build. Every product is made to perform, built to last and backed by experience.
Suspension Kit Installation
Suspension upgrades only work when they’re installed correctly. That’s why we handle the full installation process in-house using the proper tools and equipment. Every EFS kit is fitted by experienced tradespeople who take the time to get it right. From initial checks to final fitment, we ensure everything lines up, sits level and performs safely under load.
We also carry out calibration and post-install testing to ensure consistent handling, ride height and comfort. Our workshop handles suspension installs for 4WDs, caravans and light commercial vehicles. If you’re upgrading an old system or fitting suspension to a new setup, we’ll take care of it from start to finish.
Performance Benefits
Upgrading your suspension improves more than just comfort. It helps with control, handling and overall vehicle stability. A quality suspension setup gives you better load support, less body roll and more confidence on rough roads. It also improves traction, steering response and tyre wear — all key for safe touring and daily driving.
We’ll help you select a system that suits your vehicle’s weight, usage and driving conditions. Whether you tow a van, hit off-road tracks or want better control on country roads, upgraded suspension can make a real difference. You’ll feel the improvement every time you drive.
