4WD Torsion Lift Kits

Enhancing your 4x4 with a torsion lift kit is among the simplest and most cost-effective modifications you can make. On this page, we'll explore the significance of upgrading your torsion bars and the essential role a heavy-duty (HD) torsion bar plays in your 4WD's performance.

Are you interested in elevating your vehicle with a torsion bar lift kit? Contact us today at 1800 654 885 or send us a message. You can also explore our selection of 4WD torsion lift kits by using the vehicle search on our website.

We're proud to offer HD torsion lift kits as an upgrade option for all our lift kit packages, ensuring your 4WD receives the support and lift it needs for optimal performance.

Understanding HD Torsion Lift Kits

Heavy-duty torsion bars are crafted from robust, hardened steel capable of withstanding significant torsion. Positioned within the suspension system, one end of the torsion bar is securely attached to the vehicle's chassis, while the other end connects to either the lower or upper control arm. The principle of torsion involves twisting the bar under applied torque, which occurs as the front wheels of a 4WD navigate elevation changes. This twisting action transforms the torsion bar into an effective spring mechanism, providing essential support to maintain the vehicle's front-end height and stability.

Our HD torsion lift kits and torsion bar lift kit options are designed to bolster your 4WD's suspension, enhancing its ability to tackle challenging terrains while ensuring a smoother ride. Whether you're venturing off-road or navigating daily drives, upgrading to an HD torsion lift kit can significantly improve your vehicle's performance and durability.

Why do I need an HD Torsion Lift Kit?

There are a few reasons why you would need an HD Torsion Lift Kit!

  1. If you are carrying increased front load bearing accessories (bull bar, winch, batteries, etc) then you need to get a HD Torsion Bar to support the increased load. If you do not, the front end of your vehicle will sag.
  2. If you are looking to get increased lift in the front and are carrying increased front load then you need a HD torsion bar that can both support the weight and also be adjusted to raise the front without concern of failure.
  3. You may say, well I can just adjust my factory torsion bar. Yes, you could but this would cause more harm than good. By adjusting your factory torsion bar, instead of upgrading to a HD torsion bar. You will solve the sag short term, but your factory torsion bars will weaken and constantly unwind, plus your wheel alignment will always be out due to the ever changing height.
  4. If you do not upgrade to HD torsion bars when carrying increased front load or when looking to lift your 4wd, then your front tyres will wear much faster than normal. This is because if you use a factory torsion bar your wheel alignment will never be correct due to Height Changes and Increased load Carrying. Costing you lots of money.
  5. If you adjust your factory torsion bar to a 40mm lift height and are carrying increased front loads, you will find that after going off road or even after a day of driving on road. The next day your torsion bar will have unwound and your front end will be sagged.

So, if you’re looking at getting a 4x4 lift kit and have 4x4 accessories installed in the front, like a bull bar and winch. Get a HD torsion bar upgrade to ensure you get your desired lift and the best possible performance from the lift kit.

Torsion Bar Lift Kit - Frequently Asked Questions

Do I need to upgrade my torsion Bar?

If you have lifted or are thinking of lifting your 4WD, then yes, you will need to upgrade your torsion bar. If you don’t upgrade your torsion bar, then you may not get the correct lift height. Additionally, if you are carrying any increased load bearing accessories you will need a HD torsion bar to help support the increased load. If you do not upgrade to a HD torsion bar after installing front load bearing accessories such as a bull bar, winch, or battery. Then the OE torsion bar could fail. Yes the OE torsion bar can be wound up, but you will have to do this regularly as the front end will progressively sag. This will keep happening until the torsion bar breaks.

When do I need an HD torsion lift kit?

If you are planning to do a tonne of 4WDing and are using a standard torsion bar for increased lift, then it’s recommended to get a heavy duty torsion bar installed. Standard bars can only be twisted so much before failing. When you use a factory or standard torsion bar to create more lift in your vehicle, you have ultimately used their maximum torsional value. Whereas heavy duty torsion bars will give you the desired lift without maxing out their torsional values. Additionally, HD torsion bars are larger and stronger, designed to carry more weight. So if you have front accessories installed, you should get a HD torsion bar to avoid sag. 

Can’t I just use my standard torsion bar?

Yes, you can, but if you are carrying any increased front load, you risk the torsion bar failing. Additionally, the factory torsion bar will progressively sag. Upgrading to a HD torsion bar avoids all these problems.

If I use my standard torsion bar, will I still get a lift?

You will still get some lift out of your standard torsion bars however not the desired lift you are wanting. In addition, adjusting your standard torsion bars for a higher ride height will put increased strain on your torsion bars which can cause failure down the track. This issue is compounded if you are carrying increased front-load accessories. 

How do I adjust my Torsion Bar?

As soon as your vehicle hits a bump or mound and moves in an upwards direction, tension is created and the bar twists. After the bump, the bar pushes the wheel downwards again and unravels back to its original state. Torsion Bars are typically mounted vertically with a 4WDs chassis allowing them to have greater length for up and down wheel movement. Torsion Bars usually have splined ends that are mounted in anchor points called “keys"'. These keys can be adjusted with the torsion bars bolts to vary and change a vehicle's overall ride height. For instance, as the torsion bars bolts are turned to the raised position, the ride height of the vehicle will increase and if it is lowered the ride height of the vehicle will decrease. A torsion bar's spring rate is determined by its overall thickness, diameter, length, and material.
