Although they accomplish very similar tasks, torsion bars function very differently than traditional coil or leaf springs. While a typical spring compresses vertically up and down , a torsion bar provides its tension by a twisting action.
One end of a torsion bar is rigidly attached to a frame cross member while the other is attached to a control arm pivot. Our favorite feature of torsion bars is that they are super-simple to adjust for ride height. The easiest way to safely lift your factory torsion bars is to upgrade the torsion keys. Torsion keys are machined steel plates that hang out on the frame ends of torsion bars and their job is to facilitate the adjustments in ride height.
With a decent set of jack stands and a torsion bar unloading tool readily available for purchase and easy to rent from major auto parts stores , the average handyperson can have a set installed in an hour or so.
Torsion keys are usually purchased as an aftermarket item to add to your truck. These aftermarket keys, are a slightly different shape than leveling keys which are probably on the suspension system.
This different shape will allow you to adjust the suspension even higher than just using the leveling keys alone. This does allow you to raise the suspension even higher, but you have to remember a few things.
Increasing the height will not affect any issues you may be having with ride quality nor it will change any problems you may have with the suspension. When you decide to use torsion keys to change the height of your truck, you should remember a few things. You should always double check that the height is the same on both sides of your truck.
And it is a good idea to have your truck aligned after adjusting it with the torsion keys. Since trucks are designed to carry heavy loads in the back, factories take this in to account by making the back of the truck higher to start with. This way, over time and with heavy loads, the rear will settle down.
Eventually it will even out with the front end of the truck. If you want to have the front and rear of your ruck level immediately, you need to use the torsion levels and possibly torsion keys, depending on how much height you want to add. Most trucks will already come equipped with a torsion leveling system. These levels generally give you a turn or two to add a little bit of height to the front end of our truck.
If you want to add more, you need to use the torsion keys to lift the front end. The torsion keys are placed on top of the levels that are already on the torsion bars on your truck. The keys can be turned and will give you some additional height on the front end. You do need to be careful though. When you use the torsion keys to get that extra lift, you should know that this will add more pressure to the torsion bar.
Some people feel that this added pressure to the torsion bar will make your rider rougher. And the undue stress is not always beneficial for the system as a whole. And if you plan on using your raised truck for off road driving, it can place undue stress on the joints of your truck and that can lead to them breaking.
Aftermarket torsion keys should be purchased with caution. Be sure to check that the keys you are purchasing will be compatible with the make and model of your car. And if you want extreme height, consider having the whole truck lifted so it will be less taxing and damaging to your vehicle.
Btw, if you are driving a truck, you should have the best trucker gps , it will help you find the way when drive. Truck owners purchase trucks for many reasons.
They are used to haul heavy loads, go off roading or just for street use. Trucks will normally have the front end be lower than the rear.
