What Different Spring Types Do?

When it comes to choosing your springs, it’s often a trade off between comfort and performance. Grabbing the right set of springs for your vehicle can greatly increase your driving pleasure, and it’s great to know what types do what when it comes to choosing your ride height.


Standard/Heavy Duty Standard Springs



Standard springs, such as the King Springs you see above, are set at the normal height of cars you generally see on the road. Standard height springs are geared towards comfort and reliability or the replacement of used up and sagged springs, aiming to provide a more even balance between responsive handling and comfort. This enables you to tackle most of the bumps and obstacles you’re likely to face driving on the road every day. Many standard springs are also made out of heavy duty steel to provide increased running life and resistance to towing & carrying heavier loads, without having to go to the extent of raising your vehicle’s springs. If you’re after even more towing capacity, it’s worth checking out pairing some HD springs with an Airbag suspension system.


Raised Springs



Raised springs are largely applied to 4×4 and commercial uses, as when combined with a high-pressure, long-travel shock absorber they can provide a great deal of reliability under the heaviest strains you can place upon a vehicle. Raising your vehicle serves two main technical purposes: they raise the ride height and suspension travel of a vehicle, enabling it to tackle rougher terrain and provide more security for vehicles heading off-road and into deep water on a regular basis. Secondly, raised springs provide the stability to work under much higher pressures, giving them the ability to provide a greater quality of handling and ride comfort when the vehicle is towing or regularly carrying heavy loads. For this reason, one of the main factors of many 4×4 Lift Kits are raised, toughened springs.


Low Springs

Generally speaking, the lower your car’s body is raised off the ground, the more responsive the car will feel. Lower suspension will travel less and provide a firmer ride along with a lower centre of gravity, allowing you do feel the road more organically. The lower travel also reduces the car’s capacity to roll, meaning the body will travel less when cornering at speed and your handling is significantly improved. This, along with the obvious aesthetic appeal that comes with lowering your ride height, means that lower springs are often one of the first modifications made by car enthusiasts and customisers across many sports cars.


Super/Ultra Low Springs

Super/ultra low springs challenge the limits (both performance-wise and in the eyes of the law) to just how low you can bring your car to the surface of the road. Super low cars generally have the best handling performance, but only on incredibly smooth roads and tracks. As such, you’ll often see the smallest springs on supercars and heavily modified track cars. If you want the ultimate responsiveness from your handling on the track, the least body roll and the most imposing look from your ride, grab some super low springs, but check state regulations to make sure they’re legal first.
