Best Coil Springs for Jeep XJ, TJ, JK – Buyers Guide:
1. Lift Height: A Crucial Factor:
First of all, you should consider your desired lift height when choosing coil springs for your Jeep. The lift height determines the ground clearance and off-road obstacle clearance of your Jeep.
The available lift heights for coil springs range from 2.5 to 6 inches. It is essential to choose a lift height that matches your intended use and tire size.
2. Material: A Significant Consideration:
Materials used to manufacture coil springs are another critical factor to consider. The majority of coil springs use high-quality steel alloy, which should be durable, robust, and resistant to rust and corrosion to endure the demands of off-road driving.
3. On-Road and Off-Road Performance: A Distinguishing Element:
Different coil springs are designed for varied levels of on-road and off-road performance.
If you plan to use your Jeep primarily for street driving, you should opt for coil springs that offer a comfortable ride and stable handling.
On the other hand, for off-road use, you require coil springs that can absorb shocks and provide good articulation.
4. Load Capacity: A Vital Factor:
The load capacity of coil springs is another important consideration. If you intend to carry heavy loads such as equipment or gear, you need coil springs that can handle the extra weight without affecting the ride quality or sagging.
5. Brand and Price: An Essential Element:
Lastly, the brand and price of coil springs should be taken into account. You should invest in high-quality coil springs from well-known brands that produce reliable and durable suspension components. However, premium coil springs can come at a higher cost.

How to Identify a Weak Coil Spring: Signs and Symptoms?
1. Rust or Corrosion:
Coil springs are made of metal, which can rust or corrode over time, especially in wet or salty environments.
If you see rust or corrosion on your coil springs, it could be a sign that they’re weakening and may need replacement.
2. Inconsistent Ramp Angle or Kinks:
If you notice that the coil spring has an inconsistent ramp angle or kinks in its shape, this could be a sign that the spring has been compromised and may not provide the support your vehicle needs.
3. Excessive Sagging or Leaning:
A vehicle with weak coil springs might exhibit excessive sagging or leaning to one side when parked, even without any additional load.
Additionally, the vehicle might sway more than usual when driving, especially when turning or loaded with passengers or cargo.
4. Worn or Missing Jounce Bumpers:
Jounce bumpers are rubber components that cushion the impact between the suspension and chassis when the coil spring compresses.
If these bumpers are worn, smashed, or missing, it’s a sign that the coil spring is no longer providing adequate support.
5. Suspension Stop Marks:
If you notice marks on the suspension stop where the jounce bumper impacts, it could be an indication that the coil spring is weak and causing excessive compression.
6. Uneven or Excessive Tire Wear:
Weak coil springs can negatively affect a vehicle’s handling and ride quality. If the springs can’t maintain proper ride height, it can cause the vehicle’s alignment to be off, leading to irregular tire wear patterns.
Frequently Asked Question:
1. What Is the Spring Rate On Jeep TJ Front Coil?
The front coil spring rate for a Jeep TJ is 170 pounds per inch.
2. What Is the Rear Coil Spring Rate On a Jeep TJ?
The coil spring rate for the rear suspension of a Jeep TJ is 225 pounds per inch.
3. Should I Replace All Coil Springs?
If a vehicle’s springs are replaced in pairs, it will restore the original ride height and comfort.
But if only one spring is replaced, it can cause an imbalance, resulting in an uneven ride. This can lead to the other spring being subjected to greater stress, reducing its lifespan.
4. How Many Years Do Coil Springs Last?
The typical lifespan of springs used in the industry ranges from 10,000 to 15,000 uses, or approximately 5 years.
However, it is possible to extend the lifespan of the springs beyond 100,000 cycles by utilizing extra long life springs, which are made from thicker wire.
Choosing the best coil springs for your Jeep XJ, TJ, or JK can greatly improve your off-road driving experience.
