How Do You Clean Coilover Threads?

Coilover Threads

A set of coilovers can make your car handle better and look meaner, but the ride is only as good as those soft strut mounts allow. More often than not, you’ll find yourself wanting to change up spring rates and dampening settings to find that perfect combination of performance and comfort. And when it comes time for an oil change or even a spring replacement, the best option you have is buying new stuff all together — much like shocks and struts — these parts will need to be serviced every so often. If you’re planning on doing this service yourself just know that there are some special considerations that must be taken into account prior to working on them.

#1 Lubrication Is Key!

Did you just say that you were planning on working on them dry? That’s not exactly the brightest idea. One of the major factors that cause problems for coilover internals is dirt and rust (among other things). Ammonia-based cleaners are harmful to rubber, plastic, and elastomers. This can lead to drastically shortening their lifespan or even render them useless if they’ve been submerged in water for an extended period of time.

#2 Use The Right Tools

Working with coilovers requires some specialty tools like shop stands, spring compressors , jack stands, etc… So while you may have all the supplies you need to service your shocks it just makes good sense to do a little research before taking apart something that could potentially send metal shrapnel flying all over the place.

#3 Anti-Seize Lubricant

Many of you are familiar with blue loctite, but it’s not recommended that you use this on your coilovers. Not only will it cause problems when changing out springs, but if there is any rust or corrosion it can turn into a bigger problem and lock things in place faster than you can say “Are these threads messed up?”

Thread cleaners such as CLR and other abrasive chemicals to clean the thread before applying anti-sieze grease. Another solution would be flushing your shock with brake cleaner or penetrating oil then spraying with wd40 to flush again and lubricate the fresh new treads for installation… But I still like to use anti-seize on my coilover threads (or any thread for that matter). It acts like harden grease, but it doesn’t make your stuff stick together.

Reasons Why You Should Clean Coilovers:

Coilovers are an integral part of any vehicle suspension system. When they’re dirty, they can affect the performance of your car. Here are some reasons why you should clean your coilovers: 

1) It helps maintain the good looks of your vehicle.

2) It prolongs the life of your coilovers as dirt and other contaminants could cause damage to it over time. 

3) You will have a better understanding on how your suspension system works when you clean it, this knowledge can help optimize your car’s suspension system for better performance. 

4) If you are planning to change or switch spring rate or dampening settings, cleaning the springs would make adjusting easier since dirt and oil covering them could make a difference in terms of desired height and weight distribution.  

6 Ways To Prevent Your Coilovers From Dirt And Rust

The coilovers are an essential part of your suspension system that should be taken care of to ensure the safety and durability. You can take a few precautions to make sure that dirt, dust, and other contaminants don’t ruin them.

Cleaning The Threads:

The first thing that you should do before working on coilovers is to give them a thorough inspection all angles paying special attention to the threads. Make sure that there’s no dirt in the thread or in the mating areas where coilovers are installed. Also check for any signs of rust, chipped paint, and corrosion anywhere near the threaded holes. Cleaning these parts will ensure free movement of your suspension components which is crucial to their functionality.

Cleaning The Springs:

The springs are what wraps around the shocks/struts when you compress them into place with a spring compressor tool . They’re usually quite dirty especially when they’ve been used heavily on unpaved roads or somewhere else where there has been excessive dust/dirt accumulation during driving. You can clean your coilovers by scrubbing it with warm soapy water making sure that all surfaces are covered. Leave it to dry for a couple of hours.

Cleaning The Dampening Units:

The dampening units are what separate your car suspension from a high-end shopping cart found in your local supermarket when it comes to shock absorption and preventing bouncing on uneven surfaces when you drive over them. Your coilovers have these units or components inside them which is why they should be cleaned periodically like the spring and any other part of the suspension system where dirt and dust accumulates.

Cleaning Your Shocks:

  Before servicing your coilovers, make sure that all components including the shocks themselves are completely free from dirt and rust. If you can’t avoid driving through dirty or dusty roads then cleaning your shocks at least every few months will help prolong its lifespan. You can clean them by spraying with an aerosol spray or using brake parts cleaner to remove the excess dirt, oil, and rust.

Cleaning Your Struts:

The good thing about cleaning your struts is that it’s easier than cleaning your shocks due to their simple design which allows you to detach the piston assembly from the mounting base easily. If you can find a way to remove it then wash by spraying with an aerosol spray or brake parts cleaner in between the cylinder and rubber seals thoroughly. Give everything time to dry before assembling it back in place including lubricating all components with anti-seize grease like this .

Taking Care of Your Coilovers:

As I’ve stated above there are several steps involved when caring for your coilovers. With the help of this article, cleaning your coilovers doesn’t have to be a daunting task. Keeping them clean will ensure that they’ll work in their optimal condition which results in better handling and performance when you’re on the road.


When driving on unpaved roads or in dusty areas, it’s important to clean your coilovers regularly to prolong its life and performance. The good news is that you can do this yourself at home without any special tools or extensive work required. Just make sure that your springs and other components are completely free from dirt and rust before working on them to avoid any complications when adjusting them afterwards. If you follow all steps including lubricating and assembling the components the way they were intended then you’ll be able to experience a smoother ride with improved handling even when driven through rough terrain. Cleaning your coilovers doesn’t have to be a daunting task especially when you’re equipped with this step-by-step guide which also includes for easier understanding.
