Types of Height-Adjustable Suspension

Height-adjustable suspension is a standout feature in the automotive industry, particularly in off-road and performance vehicles. It enables drivers to modify their vehicle's ride height, providing several benefits, including improved aerodynamics, better load handling, and enhanced off-road capability. The height-adjustable suspension system consists of two main types:

• Height-adjustable coilover suspension

  This type of suspension consists of a shock absorber and a spring combined into a single unit known as a coilover. The spring is wound around the shock absorber, and both components are placed on the vehicle's chassis. The ride height can be adjusted by using a spanner to turn the adjustment collar located at the bottom of the spring. Turning the collar raises or lowers the spring, affecting how the coilover fits in the mounting points. As a result, the vehicle's ride height changes. When the ride height is low, the car's handling improves, making it suitable for racing on tarmacked tracks. On the other hand, increasing the ride height makes this suspension system suitable for off-road driving.

• Height-adjustable air suspension

  Height-adjustable air suspension systems use air-filled bags (bladders) instead of traditional springs to support the vehicle's weight. These bags function like shock absorbers and hold compressed air. The vehicle's height can be adjusted by adding or releasing air from these bags. For instance, to raise the vehicle, more air is pumped into the bags using an air compressor, expanding the bags and pushing the vehicle higher above the ground. This type of suspension system is widely used in luxury cars, trucks, and off-road vehicles due to its adjustability and versatility. The ride quality can also be adjusted to suit specific driving conditions. For instance, when driving off-road, the bags can be inflated to increase the vehicle's ground clearance and accommodate rough terrain.

Specification and maintenance of height-adjustable suspension

Any business that sources adjustable ride height kits must be conversant with the specifications and maintenance requirements of the suspension systems. Here are some of those specifications and maintenance requirements.

• Spring Rate

  The spring rate of a height-adjustable suspension kit is important to the overall performance of the vehicle. It is the strength of the coil springs and controls the suspension's resistance to compression. It is measured in pounds per inch or Newtons per millimeter. When the spring rate is too high or low, the vehicle handling will be affected. If the spring rate is too high, the ride will be rough, and if it is too low, the vehicle will be bouncy. The right spring rate improves vehicle handling and ride quality.

• Shock Absorbers

  Height-adjustable suspension systems have shock absorbers with a larger diameter than standard shocks. This is because they are designed for heavy-duty use and can handle more weight. The larger shock absorbers improve the vehicle's stability and handling. Shock absorbers have a damping force. This is the resistance they give when compressed or stretched. The damping force controls the suspension's movement and helps maintain contact with the road.

• Maintenance of Height-Adjustable Suspension

  The height-adjustable suspension system must be well cared for to provide the desired service. Here is how to do that:

  1. Carry out regular inspections to ensure all components are in good condition. This makes it possible to detect wear and tear and take care of them before they become serious problems.

  2. Clean the adjustable suspension parts with a mild detergent and water to remove dirt and debris.

  3. Lubricate moving parts of the adjustable suspension system with the right lubricant. This reduces friction and prevents wear and tear.

  4. Follow the manufacturer's instructions for maintaining the height-adjustable suspension to ensure it works well.

How to Choose Height-Adjustable Suspensions

Choosing the right height-adjustable suspension kits can be tedious, especially considering the various options on the market. Here are some factors to consider:

How to DIY and replace Height Adjustable Suspension

Many truck owners shy away from having their height-adjustable suspension kits installed or replaced because of the costs involved. However, the process can be quite straightforward and easy to do. With the right tools and some mechanical experience, it is possible to replace the height-adjustable suspension on a truck.

Below are the steps on how to DIY and replace the height-adjustable suspension:

• First, set up a clean and organized workspace where the truck will be worked on. Park the truck in a level area, engage the parking brake, and ensure it is secure.
• Gather all the necessary tools that will be needed for the project. These include wrenches, sockets, screwdrivers, a jack, jack stands, and an impact wrench. It might also be a good idea to have a truck repair manual to help navigate the process.
• Disconnect the air lines from the existing shocks. Take care to note how the air lines are connected to ensure they can be reconnected in the same manner.
• Using a socket or wrench, loosen the bolts holding the shocks in place. Remove the old shocks one by one, being careful not to let the suspension drop suddenly.
• Once the old shocks have been removed, the process of installing new shocks can begin. Position the new shock absorber in the mounting location and align the mounting points. Then, tighten the bolts using a wrench or socket.
• Reconnect the air lines to the new shock absorbers. Ensure the connections are secure to prevent any air leaks.
• Once the new shocks have been installed successfully, test the height-adjustable suspension to ensure it is working properly. Make adjustments as necessary to achieve the desired ride height and comfort level.

It is important to follow the manufacturer's instructions carefully when installing a height-adjustable suspension kit. Additionally, if unsure about any aspect of the installation process, it is advisable to consult with a professional mechanic or suspension specialist.

Q and A

Q1. Who needs a height-adjustable suspension?

A1. A height-adjustable suspension is suitable for various individuals, including car enthusiasts, off-road drivers, people living in areas with poor road conditions, and those who frequently transport cargo or other large items.

Q2. Does the height-adjustable suspension affect ride quality?

A2. Yes, the height-adjustable suspension can affect ride quality. At higher elevations, the ride may feel firmer, and the vehicle may be more susceptible to body roll. Conversely, lowering the vehicle may result in a harsher ride.

Q3. Can a height-adjustable suspension be installed on any vehicle?

A3. A height-adjustable suspension can be installed on most vehicles, but it is primarily designed for cars. However, the suitability and compatibility of the specific vehicle model will depend on the suspension system.

Q4. Does a height-adjustable suspension require regular maintenance?

A4. Yes, a height-adjustable suspension requires regular maintenance to ensure proper function and longevity. This includes inspecting and lubricating moving parts, checking for leaks, and adjusting height settings as needed.
