Mastering Coilover Adjustment: No Spanner Wrench Required


Understanding The Components Of A Coilover

Before we get into the types of adjustments, let’s briefly discuss the components of a coilover. Understanding these parts will help you make sense of the adjustments you’ll be making later on. Here’s a quick rundown:

  • Spring: This is what holds the weight of the car and controls the suspension’s movement.
  • Shock absorber: This helps to dampen the spring’s movement, preventing excessive bouncing and improving the car’s stability.
  • Damper: This controls the speed at which the shock absorber moves, affecting the car’s handling.
  • Threaded shock body: This gives you access to the adjustment mechanisms.
  • Adjustment mechanisms: These allow you to make changes to the coilover’s settings.

Step-By-Step Guide To Adjusting Coilovers Without Spanner Wrench

Choose The Right Type Of Tool For The Job

Adjusting coilovers without spanner wrench is not unheard of; it can be achieved by using alternative tools. Here are some alternative tools to consider:

  • Pipe wrench
  • Vise-grips
  • Channel locks

Understanding The Right Amount Of Adjustment

Coilovers are designed to provide an adjustable suspension to improve your car’s handling and comfort levels. Overadjusting your coilovers can lead to a bumpy ride or even damage your car. Follow these tips to ensure that you get the right amount of adjustment:

  • Make small adjustments at first
  • Keep track of how many turns you’ve made
  • Check the manufacturer’s recommendation for the suitable range of adjustment

How To Adjust Spring Perch Without Spanner Wrench

The spring perch is a threaded collar that adjusts the height of the coilover’s spring. To adjust the spring perch without a spanner wrench, follow these steps:

  • Loosen the wheel lug nuts of the wheel that you want to adjust
  • Lift the car off the ground (using a jack)
  • Use pliers or channel locks to carefully turn the spring perch
  • Adjust until you reach the desired height (based on your manufacturer’s recommendations)
  • Lower the car and tighten the wheel lug nuts

How To Adjust Shock Body Rotation Without Spanner Wrench

The shock body rotation adjusts the stiffness of the damping within the shock absorber. To adjust the shock body rotation without a spanner wrench, follow these steps:

  • Locate the adjuster collar on the shock absorber
  • Use pliers or channel locks to carefully turn the collar
  • Do not overtighten or you may damage the shock absorber
  • Test the car’s ride and make further adjustments if needed

By following these steps, you can adjust your coilovers without the need for a spanner wrench. However, if you are not confident in your abilities or do not have the required alternative tools, it is always recommended to seek professional assistance.

Common Mistakes To Avoid With Coilover Adjustment

Coilovers are a vital part of the suspension system in your car that are responsible for providing a smooth ride. These mechanical devices allow you to adjust the height and stiffness of your vehicle, making it perfect for different driving conditions.

However, many car enthusiasts often make mistakes when adjusting coilovers, which can lead to additional expenses down the line. In this blog post, we’ll discuss common mistakes to avoid when adjusting coilovers without a spanner wrench.

Over Adjustment

Over adjustment is a common mistake made by many people when adjusting coilovers. It occurs when you lower the height more than recommended or stiffen the shock more than necessary, causing a harsh ride. Over-adjustment of coilovers can also cause bottoming out, leading to damages to the shock absorber.

To avoid over-adjusting your coilovers, always check the manufacturer’s recommended adjustment level, and do not exceed it. Additionally, get a friend to sit in the car while you make adjustments to ensure that your vehicle’s weight is adequately distributed and use small increments to adjust to the desired level.

Under Adjustment

On the other hand, under-adjustment is when the suspension is not stiff enough, causing a bouncy ride. This condition is more noticeable when driving over uneven terrain or when cornering. Driving with under-adjusted coilovers can also lead to tire wear or damage, which can be costly.

To avoid under-adjusting coilovers, refer to the manufacturer’s recommended settings for your vehicle. If you are not satisfied with your vehicle’s ride, make tweaks in small increments to get the desired stiffness and height.

Using The Wrong Type Of Tool

Using the wrong type of tool to adjust your coilovers can cause damage to the components or result in imprecise adjustments. Since coilovers are usually adjusted with a spanner wrench, many car enthusiasts try to use other tools, which can cause damages to the shock absorber lock rings or adjuster collars.

To avoid damages, always use the recommended spanner wrench for your coilovers. Alternatively, you can use a soft-jaw vice grip or adjustable pipe wrench as an inexpensive alternative.

Misaligned Parts

Misaligned parts can cause a range of problems for your coilovers, including loose installation, inconsistent ride height, and handling issues. When aligning your coilovers, ensure that all components are correctly installed and tightened to the manufacturer’s recommended torque values.

Ignoring Adjustments In Temperature And Weather Conditions

Ignoring temperature and weather conditions can affect the performance and functionality of your coilovers. For example, during colder months, adjusting coilovers can become more difficult due to the shocks’ decreased flexibility, leading to inaccurate adjusting. Furthermore, driving in extreme weather conditions can affect your shock absorber’s longevity and overall function.

To avoid these problems, adjust your coilovers during optimal temperature conditions, i. e. , room temperature, and take into account the weather conditions you’ll be driving in.

Adjusting your coilovers without a spanner wrench is a simple yet delicate process that requires careful attention. Always follow the manufacturer’s recommended instructions and avoid over-adjustment, under-adjustment, using the wrong type of tool, misaligned parts, and poor weather conditions. By avoiding these common mistakes, you can ensure that your coilovers operate optimally with a comfortable ride in all driving conditions.

Understanding The Different Types Of Adjustment

There are a few different ways to adjust coilovers without a spanner wrench. The two most common types of adjustments are spring perch adjustment and shock body rotation adjustment. Let’s take a closer look at each of these:

Spring Perch Adjustment

This type of adjustment involves changing the position of the spring on the shock body. The spring perch is the part of the shock body that the spring sits on, and you can move it up or down to adjust the ride height of your car.

To adjust the spring perch without a spanner wrench, you’ll need to use some other tools, such as pliers or vice grips. You can also use a hammer and a punch to tap the perch up or down. Just be careful not to damage the shock body or the perch in the process.

Shock Body Rotation Adjustment

This type of adjustment involves rotating the shock body relative to the spring. You can use this method to adjust the preload on the spring, which can affect the car’s handling and ride quality. To do this, you’ll need to loosen the lock ring on the shock body and then rotate the shock body by hand.

Again, be careful not to damage any of the components.

Explaining How Height Adjustment Works

Finally, let’s look at how height adjustment works. Height adjustment allows you to adjust the distance between the car’s chassis and the ground. This can have a big impact on the car’s handling, as well as its appearance. Most coilovers have a threaded collar on the shock body that you can adjust to change the height.

To adjust the height without a spanner wrench, you can use other tools such as pliers or vice grips. Just make sure to be careful not to damage any of the components.

Adjusting coilovers without a spanner wrench is possible, but it requires a bit of creativity and carefulness. We hope that this post has helped you understand the basics of coilover adjustment. By knowing the different types of adjustments you can make and how they work, you’ll be better equipped to fine-tune your vehicle’s suspension to your liking.

Happy adjusting!
