When my Jeep began to make a noise from under the carriage, and my tires were wearing strangely I knew that it was time to replace the coil springs. I had never had to do this type of repair before so I had to ask some of my friends who are suspension experts what was the best coil springs for a Jeep TJ.
I learned a lot about the springs, and how to select them and care for them. I also learned that if you do not know how to decompress the old spring properly, and do not have a tool to help you remove your ball joint, then you need to go see a suspension expert to help you change these over. Here, in this article, I review the 6 best coil springs for the jeep.

Top 5 Coil Springs for Jeep Wrangler Reviews
1. Moog Coil Spring Insulator
This is not a coil spring but is one of the components you need to properly install and maintain a coil spring. This item sits next to the actual coil spring is designed for placement on a rear spring. If you need a front spring insulator you must specifically order one designed for that placement.
This is not a coil spring spacer and not designed to be used as a coil spring spacer. If you are going to install spacers you put those in place, then this insulator, and then the coil spring.
This can be used on a wide variety of vehicle makes and models. You can use them on your Jeep, on some Toyotas, and other vehicles.
This item reduces the amount of noise you hear while driving. It lessens or eliminates groaning and creaking caused by the coil springs on the rear of the vehicle.
2. Moog 81055 Coil Spring Set
These coil springs will make your vehicle steering like it did when it was a new ride. They are super simple to install so you do not need an expensive trip to the mechanic, or a lot of expensive equipment to make your installation.
These springs fit a lot of different vehicles. One thing that I can tell you is the spring is slightly longer than the standard coil spring that was installed at the factory. Because of this extra length you will want to pay a lot of attention to how you orient the bottom springs.
These springs can add as much as 2” in the clearance you have under your vehicle. They are durable and long-lasting. They also have a larger diameter than most factory installed springs so they are tougher. Their diameter is about 1/8” bigger than most factory installed springs.
3. Rubicon Express RE1310 Coil Spring for Jeep XJ
These heavy-duty coil springs are made in the United States specifically to fit on the Jeep XJ that uses 4.5” springs. They can be installed on passenger vehicles that are intended to be driven on paved roads in the city and highways driving. They are also excellent for people who do some off-road driving.
This spring set can provide excellent performance without you having to add any additional components like spacers and insulators. The spring set is excellent for Jeeps and even for snowplows. They are tough and dependable, and likely to be the only set of coil springs you need on your car for as long as you own the vehicle.
These springs are very reasonably priced. The affordability of the items makes them an even greater choice for the majority of Jeep owners.
4. Moog 81069 Coil Spring Set
This amazing set of coil springs can possibly be installed without the aid of a spring compressor. They are easy to install but you need to lift the rear of the vehicle on both sides so that the tires are hanging and can spin freely. Then place a floor jack under your rear differential and remove the tires. After you remove your lower shock mounts and lower sway-bar mounts you can lower the jack supporting the rear differential and the old springs should easily slip right off.
You can retain the factory height of the vehicle with the installation of these springs. They install easily, they are durable, and you may never have to replace them.
5. Moog CC782 Coil Spring Set
These tj coil springs can return your vehicle to driving like it did when it was brand new. It will correct premature vehicle tire wear and misalignment on Jeep vehicles manufactured between 1984 and 1995.
The springs are super easy to install and most vehicle owners have the talent and tools required to make the changeover. They do not add a lot of extra height to the vehicle but they do maintain the proper clearance and provide you with more control. Depending on your old coil springs and the amount of sag they had developed these springs could increase your lift by as much as 2”.
The springs are very reasonable. They are made even more reasonably priced due to the fact that you will probably never have to buy another set of springs for the vehicle you are currently driving.
6. Rubicon Express RE1358 Coil Spring for Jeep TJ
These coil springs are developed to fit the Jeep TJ and the Jeep XJ. They are manufactured in the United States from some of the highest quality materials so they are long-lasting, dependable, and perfectly compatible to your needs.
They can provide excellent lift to your vehicle to the perfect clearance so you can drive off-road or travel around town. They will not advance the lift above 2” unless you are adding them with a lift kit for the purpose of increased height.
These coil springs are easy to install. They provide the strength and endurance your suspension needs. If you only do driving around town they will likely last you forever, or at least until the vehicle wears out.
Things to Consider When Buying a Coil Springs for Jeep TJ
Coil springs are not all made equal. You need to know a few things about this suspension component before you rush out to buy a new one. If you do not get the proper coil springs then your vehicle may be dangerous or impossible to drive.
Types of Jeep Coil Springs
You have two basic types of springs to choose from. The compression springs and the progressively wound springs. Most cars have compression springs.
Compression Springs
The compression springs are helically (spiral) wounds. This formation is made up of strong wire and is specifically designed to handle tensile loads. They are very easy to install and they are the appropriate spring for the majority of all passenger cars and trucks driving on the road.
Progressively Wound Coil Springs
These springs are made a little different and they are basically tougher than normal compression springs. If you drive in off-road situations you want this type of spring. It will give you more control under diverse situations than the common compression spring can.
Spring Materials
The most important aspect to coil springs is the material these items are made from. You have to get springs made of high-quality materials in order for them to take the punishment and last.
The best materials for coil springs are chrome-silicone and chrome-vanadium. The coils fashioned from these components are long-lasting and sturdy. They can be exposed to the tension, high-heat and moisture exposure that coils on off-road driven vehicles often see.
Diameter
The diameter of the wires that are used to shape the coil springs will play a role in the stiffness and function of the springs. The greater the diameter is the harder the spring will be to compress, and the more resistance it will provide.
Final Thoughts
Coil springs are designed to last for the life of most vehicles. It has been my experience that people who drive Jeeps and other off-road vehicles should check their coil springs for wear and tear like they check the rest of their suspension systems. I recommend new coil springs for these vehicles because they help protect and support all of the rest of the suspension components.
In my opinion, whenever you change your shocks you should see if the springs are looking good.
