Understanding Lift Springs on the Wrangler TJ

What Are Lift Springs Exactly

Lift springs are coil springs or leaf springs that are taller than the factory stock springs on a Wrangler TJ. They give the Jeep more ride height and allow for bigger tires. The suspension lift changes how the vehicle sits and performs both on and off the road.

Factory Wrangler TJ springs are designed for a specific load and ride quality. When someone adds a lift kit, they swap out those stock springs for longer ones. This is the most common way to lift a TJ. The springs support the weight of the vehicle and absorb bumps from the road.

Why People Add Lift Springs to Their TJ

There are many reasons Wrangler TJ owners add lift springs. Some want the aggressive look of a lifted Jeep. Others need the clearance for larger all terrain tires. Off road enthusiasts know that more suspension travel means better performance on rough trails.

Here are the most common reasons people install lift springs:

• Bigger tire clearance: Lift springs allow you to fit 33 inch or even 37 inch tires.
• Better off road ground clearance: You clear rocks, logs, and rough terrain more easily.
• Improved approach and departure angles: The Jeep angles better over obstacles.
• Visual stance: A lifted Wrangler TJ looks more aggressive and commanding.
• Aftermarket accessory clearance: Bull bars, winches, and skid plates fit better with extra height.

Visual Signs Your Wrangler TJ Has Lift Springs

Check the Wheel Well Gap

This is the easiest and fastest way to spot lift springs. Walk around your Wrangler TJ and look at the gap between the tire and the wheel well. On a stock TJ, the tire sits close to the fender. There is usually only a small gap of about 1 to 2 inches.

If you see a large gap, especially at the top of the wheel well, that is a strong sign of lift springs. The bigger the gap, the more lift your TJ likely has. A 2 inch lift will show a noticeable difference. A 4 inch or 6 inch lift is obvious from across the parking lot.

Quick Tip: Look at the gap when the Jeep is on a flat surface. An uneven surface can throw off your judgment. Also check all four corners to make sure the lift is even.

Look at the Spring Perch Position

The spring perch is where the coil spring sits on the axle or control arm. On a stock Wrangler TJ, the spring perch is welded at a specific height. When lift springs are installed, the perch position changes or the spring itself is simply taller.

You can see this by looking under the Jeep at the front and rear suspension. If the springs look noticeably longer than you remember, or if the perch brackets look different from factory pictures, you likely have a lift setup. Aftermarket lift brackets are often visible and may have different part numbers stamped on them.

Inspect the Shock Absorbers

Lift springs almost always come with longer shock absorbers. Stock shocks on a Wrangler TJ are sized to match the factory spring height. When you add lift springs, the shocks need to be longer to keep the proper suspension geometry.

Look at your shocks. If they are visibly longer than what you see in factory Wrangler TJ photos, that is another clue. Popular aftermarket shock brands like Bilstein, Fox, and Old Man Emu make extended shocks specifically for lifted TJs. The shock body length is a dead giveaway.

Common Mistake: Do not assume longer shocks always mean lift springs. Some owners change shocks without changing springs. Always check the springs directly for the most accurate answer.

Measuring Your Springs to Confirm a Lift

Tools You Will Need

Measuring your suspension components is the most accurate way to confirm lift springs. You will need just a few basic tools:

• A standard tape measure or ruler (at least 24 inches long)
• A flashlight for seeing under the Jeep
• A notepad to record your measurements
• A jack and jack stands for safety

Step by Step Measurement Process

First, park your Wrangler TJ on a flat, level surface. Engage the parking brake and make sure the Jeep is stable. If you want more accuracy, you can lift the Jeep with a jack and support it on jack stands.

Locate the front coil springs. They sit on top of the upper control arm and connect to the lower arm at the bottom. Using your tape measure, measure the free length of the spring from the top coil to the bottom coil.

For a stock Wrangler TJ, the front coil springs are typically around 13 to 15 inches long depending on the model year and trim. If your springs measure significantly longer, you have lift springs. Here is a simple reference:

Spring Type	Approximate Length	Lift Height
Stock Front Spring	13 to 15 inches	0 inches (no lift)
2 Inch Lift Spring	15 to 17 inches	2 inches
4 Inch Lift Spring	17 to 19 inches	4 inches
6 Inch Lift Spring	19 to 22 inches	6 inches

Expert Insight: Always measure both front springs. If one spring is a different length than the other, you may have an uneven lift or a replacement spring that does not match. Uneven springs can cause handling problems and uneven tire wear.

Measure the Rear Springs Too

Do not forget the rear! The Wrangler TJ uses rear leaf springs in most configurations. Leaf springs are stacked and held together by bolts. You can measure the arch height or the overall length to compare against stock specs.

Aftermarket rear leaf springs for a lift will be visibly taller than factory leaves. They may also have more leaves stacked together. If your rear springs look beefier or taller than stock, you have a rear lift as well.

Types of Lift Springs Available for the TJ

Coil Spring Lift Kits

The most common type of lift springs for the Wrangler TJ is the coil spring lift. These replace the front coil springs with taller versions. Coil spring lifts come in standard sizes like 1 inch, 2 inches, 2.5 inches, 4 inches, and 6 inches.

Coil spring lifts change the caster angle and control arm geometry. Most quality kits include upgraded track bar brackets and sway bar drops to compensate for the changed geometry. This keeps the Jeep driving well both on and off the road.

Leaf Spring Lift Options

The rear suspension on the Wrangler TJ uses leaf springs. Leaf spring lifts add thicker or longer leaves to increase the rear ride height. Some owners add helper springs or replace the entire leaf pack for a more aggressive rear lift.

Leaf spring lifts are common for owners who want to level their TJ. Many Wrangler TJs sit slightly nose down from the factory. Adding a rear leaf spring lift can bring the front and rear back into balance.

Body Lift vs Suspension Lift

It is important to understand the difference between a body lift and a suspension lift. A body lift uses spacers between the body and the frame to gain height. The springs themselves remain stock length. A suspension lift replaces the springs and shocks to gain actual wheel travel and ride height.

If your Wrangler TJ has a body lift, the springs will be stock length. You can check this by measuring the springs directly. Body lifts are typically 1 to 3 inches and do not change the spring perch position significantly.

How to Tell Without Removing the Springs

Visual Inspection Under the Vehicle

You do not need to remove the springs to identify a lift. A thorough visual inspection under the Jeep will give you most of the answers. Look for aftermarket parts, different colored springs, or any components that look newer or different from factory parts.

Check for any stickers, stamps, or part numbers on the spring coils. Aftermarket spring manufacturers like Old Man Emu, BDS Suspension, and Rusty’s Off Road stamp their springs with identifying marks. You can look up these marks online to find the spring specifications and lift height.

Check the Ride Height

Another simple method is to compare your ride height to factory specs. Measure from the ground to the top of the wheel well at the front and rear. Compare these measurements to stock Wrangler TJ dimensions, which are widely available online.

If your TJ sits noticeably higher than stock, you have lift springs. This method is not as precise as measuring the springs directly, but it gives you a good ballpark idea quickly.

Look for Aftermarket Parts

A lifted Wrangler TJ usually has other aftermarket parts that go along with the lift. Look for:

• Extended brake lines that are longer than stock
• Sway bar disconnects on the front axle
• Adjustable control arms that look different from factory parts
• Aftermarket bump stops mounted in different positions
• Diff drop brackets on the rear axle

These parts are designed to work with a specific lift height. Seeing them on your TJ is a strong indicator that you have lift springs installed.

What to Do If Your TJ Has Lift Springs

Verify the Lift Height

Once you confirm you have lift springs, the next step is to verify the exact lift height. Knowing your lift height helps you plan future upgrades and ensures your current setup is correct. Measure your springs and compare them to lift kit manufacturer specifications.

Quick Tip: Keep a record of your lift height and spring specs. This information is valuable if you ever sell the Jeep or plan additional upgrades. Future buyers will appreciate the detailed information.

Check for Compatibility Issues

Lift springs change the geometry of your Wrangler TJ. Over time, some components may wear out faster or need adjustment. Check your tie rod ends, ball joints, and control arm bushings regularly. A lifted TJ puts different stress on these parts than a stock setup.

If you notice any vibrations, clunking noises, or uneven tire wear, have your suspension inspected. These can be signs of worn components or incorrect lift geometry that needs correction.

Plan Your Next Upgrade

Knowing your current spring setup opens the door to your next upgrade. Maybe you want to go from a 2 inch lift to a 4 inch lift. Or perhaps you want to add a body lift to gain more interior clearance. Whatever your goal, starting with a clear understanding of your current springs is essential.

Consider upgrading your shock absorbers if you have not already. Quality shocks make a huge difference in ride quality and control. Brands like Fox 2.0, Bilstein 5100, and King shocks are popular choices for lifted Wrangler TJs.

Common Mistakes People Make When Checking for Lift Springs

Many owners make simple mistakes when trying to identify their spring setup. Avoid these common errors to get accurate results.

• Assuming all aftermarket parts mean a lift: Some owners add aftermarket shocks or sway bars without changing the springs. Always check the springs directly.
• Measuring on an uneven surface: This throws off your ride height readings. Always measure on a flat, level surface.
• Forgetting the rear springs: Many people only check the front and miss a rear leaf spring lift.
• Guessing by tire size: Bigger tires do not always mean lift springs. Some owners run larger tires on stock springs with a body lift.
• Not comparing to factory specs: Always have factory measurements handy for comparison. Online forums and Jeep databases are great resources.

Final Thoughts

Figuring out if your Wrangler TJ has lift springs is a straightforward process. Start with a visual inspection of the wheel well gap, shock length, and overall ride height. Then move on to measuring the springs directly for the most accurate answer. Compare your findings to factory specs and aftermarket lift kit charts to confirm your lift height.

Whether your Wrangler TJ has stock springs or a full suspension lift, knowing what you have is the foundation for any future upgrades.

Frequently Asked Questions

What is the easiest way to tell if my Wrangler TJ has lift springs?

The easiest way is to check the wheel well gap. A lifted Wrangler TJ will have a noticeably larger gap between the tire and the fender compared to a stock TJ. Look at all four corners for an even comparison. This visual check takes less than a minute and requires no tools.

Can I have lift springs without a full lift kit?

Yes, it is possible. Some owners install aftermarket coil springs without replacing the shocks or other components. This is sometimes called a spring swap. However, a spring swap alone may not provide the best ride quality or handling. Always check all suspension components together for the full picture.

How do I know if my Wrangler TJ has a body lift or suspension lift?

Measure your springs directly. If the springs are stock length, you likely have a body lift with spacers. If the springs are taller than factory specs, you have a suspension lift with lift springs. You can also check for a body lift by looking for gaps between the body and the frame at the bolt points.

What lift height do I have if my springs measure 18 inches?

An 18 inch front coil spring on a Wrangler TJ is likely a 4 inch lift spring. Stock springs are typically around 13 to 15 inches. However, always cross reference with the spring manufacturer’s specifications to be sure. Different brands may have slightly different measurements for the same lift height.

Do lift springs affect my Wrangler TJ’s steering?

Yes, lift springs can affect steering geometry. A lifted TJ changes the caster angle and may cause the steering to feel different. Most quality lift kits include steering corrections like adjustable track bars and control arms. If your steering feels loose or pulls to one side, check your alignment and suspension geometry.

Are lift springs the same as leveling springs for the Wrangler TJ?

Not exactly. Lift springs raise the entire vehicle for more wheel travel and tire clearance. Leveling springs are designed to correct the factory nose dive and bring the front and rear to a more even height. Some leveling kits use shorter lift springs in the rear to balance the TJ without adding significant ground clearance.
