What is the lift height difference between the 2-door and 4-door Jeep models?

These springs are designed to provide a 3.0-inch lift on the 2-door Jeep JL models and a 2.0-inch lift on the 4-door JLU models. This accounts for the different factory suspension setups and weight differences.

What material are these springs made from and how are they treated?

The springs are made from high-tensile steel, chosen for its strength. They are also shot-peened, a process that improves their fatigue life and makes them more resistant to cracking over time.

Does this kit include everything needed for the lift?

This kit includes the rear lift springs only. Depending on your vehicle and intended use, you may need to consider additional suspension components like shocks or control arms to complete the lift.

Product Details

These rear lift springs from Synergy Mfg are built with a specific spring rate designed to give your Jeep JL 2-door a 3.0-inch lift and your JLU 4-door a 2.0-inch lift. They are made from high-tensile steel, which is a strong material that can handle the stresses of off-road driving and carrying extra weight. The springs are shot-peened to improve their fatigue life, meaning they're built to last through many cycles of compression and extension.

When you're looking to add larger tires or improve your Jeep's stance, these springs are a solid option. They are designed to work with your factory suspension components, making installation more straightforward. The difference in lift height between the 2-door and 4-door models accounts for the different factory suspension setups and weight distributions between those configurations. This ensures you get the intended lift amount for your specific Jeep JL or JLU.

This kit includes the rear springs only. You may want to consider other suspension components to complement the lift, such as longer shocks or adjustable control arms, depending on your specific needs and how you plan to use your Jeep.
