The first thing you notice about these adjustable aftermarket control arms is they have a lifetime warranty from the Rough Country Store. Lifetime warranties make you feel more confident that the part is a sturdy and durable one.

They are perfect fit replacements for the Jeep Wrangler TJ which was manufactured from 1984 until 2001 and the Cherokee XJ MJ. They are a little shorter than the stock arms that came on the vehicles but they still provide excellent control.

What to Consider Before Buying Adjustable Control Arms for Jeep Wrangler

When you go to replace the control arms on your vehicle you do have options to consider. These items are made from different materials, and although each material offers a specific benefit for the driver, each one also offers a specific negative drawback as well. Consider your driving style, the climate you live in, and the vehicle that you drive when choosing these parts for your car.

Control Arm Material

You are going to find these items made from cast aluminum, cast iron, and stamped steel. Each material is specifically better for some things than the other materials are.

Cast Aluminum

The control arms made of cast aluminum are lighter than the other varieties. They are also rust-resistant and will not corrode due to exposure to wet or humid conditions. They work well in all climates.

If you drive off-road or over rough streets that have a lot of potholes the cast aluminum variety of control arms may buckle or become distorted due to the rough terrain.

Cast Iron

Cast-iron control arms are normally shaped like a wishbone. They have more strength than the cast aluminum, and they can endure rough road terrain without buckling.

Stamped Steel 

Stamped steel control arms are the least expensive of all of the control arms. Stamped steel control arms are often found on older model vehicles. They have a tendency to rust and corrode so they are not as durable as the cast iron or the cast aluminum varieties. They are not as easy to damage or buckle when driven over rough terrain.

OEM Vs. Aftermarket Adjustable Control Arm

OEM is the original equipment that the manufacture-installed on your vehicle. When you choose OEM parts then you know you are getting parts that are designed to fit the vehicle perfectly with no alterations needed.

OEM parts are designed to provide you with everything your vehicle actually needs. When you choose these parts, you are replacing your broken item with an exact replica of the part the manufacturer thought was best for the make and model of car that you have.

Aftermarket control arms can fit exactly like the OEM but you have to get all of the exact measurements and make sure that the aftermarket part is a perfect fit for your vehicle.

Aftermarket parts can give you a smoother ride or allow you to do things like replacing the shocks with absorbers that would not fit with the OEM parts.

Aftermarket control arms may be better suited to driving off-road and over rough terrain.

Choosing OEM or aftermarket is basically a personal preference. You have to decide what each part may do for your vehicle, and if one of them offers more benefits than the other.

Single Control or Full Kit

Sometimes you need to replace a single control arm, and sometimes you want to redo the entire suspension and replace everything with new equipment.

Before you can compare the price of a control arm you have to ascertain whether you are looking at a single item or a complete kit with multiple pieces.

There are a lot of different features designed for these suspension pieces. Some of the most common features are:

Adjustable Control Arm FAQ

How Long Does It Take to Install Control Arms?

Replacing the control arms will take an experienced mechanic between one and two hours. If you are inexperienced it could take you a lot longer. This change over is fairly difficult, say an 8 on a scale of 1 to 10.

Can I Install My Control Arms on My Own?

Yes, you can do this job for yourself if you have the right tools. Give yourself ample time to do the job and make sure you have assembled all of the tools needed before you begin. If you do not own a ball-join separator you can often rent these tools from local auto supply stores.

Should I Buy Aftermarket Control Arm Set?

After-market control arms are often lighter than the original factory control arms the vehicle had. The changing of these components can also allow you to use replacement shocks that are more advanced than the traditional shocks installed at the manufacture of the vehicle.

What Is A Caster Angle?

The caster angle is actually an imaginary line that runs between the upper and lower pivotal steering points on the suspension of your vehicle. The slope of that line is commonly referred to as the caster angle.

What Tools Do I Need for Control Arm Installation?

You will need a jack to lift the vehicle, a jack stands to support the vehicle, and wheel chocks to keep it from rolling off of the jacks. Then you will need a ball-joint separator, a hammer, a ratchet and sockets, and open-end wrenches that have the box end on the opposite end. You may need a breaker bar as well.


This article covers the recommendations for the best adjustable control arms for a JK. I researched a lot of different control arms before writing this article. I also sought the advice and instruction of suspension experts near me.

The control arm is an important part of your suspension. It basically connects the front wheels of your car so that when you turn the steering wheel the front wheels respond to your command. I recommend choosing these items carefully because they determine how much control you have over the vehicle.

Control arms are made in specific lengths and their fitment must be precise. The Freedom Offroad adjustable control arm allows it to fit a larger number of vehicles. 

When selecting the perfect control arm think less about price and more about the durability and precision of the suspension component.
