Your vehicle's springs are critical to safe handling and a comfortable ride. Theymaintain a constant height and provide elasticity to absorb road irregularities. The spring not only holds the car and maintains clearance on the road. It also determines how the car will react to obstacles. Manufacturers of springs design them so that the body does not sag too much during the transportation of goods or passengers. And if you need to transport more cargo in the car, you canbuy reinforced springs, which are made for almost all cars.

Allsuspension elements, such as levers, rods, stabilizers, ball bearings and silent blocks, exist only so that the spring can do its job:compensate for road irregularities, so that the wheel always remains in contact with the road.

What are the springs for?

Helical or spiral springs are made of hardened steel wound in the form of a spiral. Most modern cars have these suspension elements on the front axle, and quite a few pickup trucks and SUVs have them on all four wheels. If on your cara suspension with McPherson struts is installed, the spring goes around the shock absorber, and both elements are attached to the rack. If your car does not have racks, then coil springs andshock absorbersare attached separately.

What is the degree of compression of a spring?

The main parameter is stiffness. The higher the stiffness of the spring, the more force must be applied to compress it. This characteristic is influenced by other parameters, including outer diameter and height, shape, turn pitch, wire diameter, number of turns, and material characteristics. Stiffness also depends on the diameter of the bars: thicker bars make the spring stiffer.

The length of the springis its unstressed length, and the longer it is, the higher the stiffness.

In the same springstep turns(distance between turns) can be constant or variable. Short coils soak up small bumps in the road well, while long coils maintain suspension stiffness and controllability.

Popular forms of springs:

1. Barrel-shaped: Have a convex outer and concave inner surface for increased load capacity. Since the stiffness varies unevenly, such springs adapt well to the load.
2. Hourglass springs: Unique shape with a narrow central part and wider ends provides increased flexibility and resistance to bending under high load conditions.
3. Conical: Have variable-pitch coils that do not make contact with each other during compression and are characterized by a longer stroke, more progressive compression resistance and increased load capacity.
4. Normal (cylindrical): These are cylindrical springs with the same diameter and pitch. Turns of the same diameter collide with each other during full compression and offer linear resistance.

Advantages of spiral springs:

Suspension coil springs are used, providing the largestversatility in different conditions. They allow for a comfortable ride for unloaded cars and become stiffer as weight increases, increasing stability without bouncing and preventing a significant reduction in ground clearance.

For sports cars with low ground clearance, coil springs are bettersmooth out inequalitiesduring normal street driving and become stiffer in corners, reducing body roll during aggressive driving. Spring suspension for SUVsallows you to increase the suspension strokeon rough terrain and get contact with the surface even in the most difficult terrain.

Disadvantages of helical springs:

If we compare them with springs, springs do not carry heavy loads so well. The weight of the machine is concentrated on a smaller surface area, whileleaf springsdistribute the load evenly.

To save weight, some manufacturers make the springs thinner and lighter, but such lightness is more susceptible to sagging and failure under pressure, especially if corrosion occurs. Some spring manufacturers such asIronmanorOME, a strong coating is applied to the springs, which is designed to prevent the appearance of rust and the puncture of tires by fragments.

When to change springs?

Over time, torsion springs wear out andbegin to sag, as a result of which the car's clearance decreases. Also a springmay be broken, if the height of the suspension is noticeably different on the left and right sides of the car. These problems become more apparent when you add even a small amount of weight, such as a passenger or two in the back seat. Broken springs can also produce a noticeable rumble and cause damage to other parts. Theirshould be changed immediatelyin order not to "get" more expensive repairs.

Springs are often used in cars with multi-link suspension, so if the suspension height is disturbed, itcan affect wheel camber and tire wear. To check if your suspension height is too low, you can find the specifications in your owner's manual or online and compare them to your own measurements.

Which springs to choose?

If you just need to replace a part that has failed, and you are satisfied with everything in the suspension, then it is better to choose the original spring (you should change the springs in pairs, so as not to subject the new spring to faster wear together with the worn one on the other side of the axle).

If you want to improve the characteristics of the suspension, we have itreinforced springsfrom the world's best manufacturers designed for this. We also offer suspension lift kits, spacers, and leveling kits for SUVs and pickup trucks (which raise the front of the vehicle more than the rear to level the vehicle relative to the ground).
