  • Variable Length Coil Spring Spacer:  By adding or removing spacers, the ride height can accommodate different tire sizes, ground clearance requirements, or personal preferences.

  • Adjustable Lift Height From 2.0" to 4.0":  Increasing the lift height provides additional space for fitting larger tires. Larger tires offer better traction and improved off-road performance, allowing you to conquer challenging obstacles with ease.

  • Improved Handling and Stability: By addressing uneven load distribution, spring settling, and sagging, you can restore the vehicle's proper ride height and weight distribution. This helps maintain optimal suspension geometry and improves handling and stability, especially during cornering and maneuvering.

  • Increased Ground Clearance: This is particularly important for off-road or rough terrain driving, as it helps prevent the undercarriage from hitting obstacles and reduces the risk of damage.

  • No More Coil Springs:  Not having to replace coil springs streamlines the modification process. You can focus on the specific changes you want to make, such as adding a lift kit or upgrading suspension components, without the added complexity of spring replacement.

  • Technically Advanced Design:  Billet construction, which involves CNC machining from a solid block of material, provides exceptional strength and durability. This visual upgrade can give your vehicle a more aggressive and high-performance look

  • New Dura-Thane & Bump Stops:  Unlike traditional rubber components that may degrade or deteriorate due to exposure to environmental factors like heat, cold, or chemicals, Dura-Thane materials exhibit excellent resistance to wear, tear, and degradation.
Also fits Jeep Wrangler JK right hand drive models.
