Key Features & Specifications

Standout Features

• Dual-Rate Coil Springs (Front and Rear): These springs are engineered to provide a progressive spring rate, meaning they are soft over small bumps for comfort but firm up under compression to prevent bottoming out. ICON guarantees they will never sag, ensuring consistent ride height and performance over the vehicle’s life. This is a key feature that makes many people decide to buy ICON stage 4 lift system.
• High-Steer Flip Kit: This clever design relocates the steering linkage above the axle centerline. It eliminates the need for a bulky drop pitman arm, improves steering geometry, and significantly increases ground clearance at the front axle. This is a massive advantage for rock crawling.
• Stainless Steel High-Steer Taper Adapter: This precision-machined part allows the high-steer kit to be installed without drilling into the factory knuckle. It maintains structural integrity and simplifies installation.
• Adjustable Track Bars: The front and rear track bars are on-vehicle adjustable. This allows you to perfectly center the axle under the vehicle after the lift is installed, eliminating the common issue of a crooked Jeep.
• Dual-Rate Bushings and PTFE-Lined Rod Ends: All links and track bars use a combination of dual-rate bushings and PTFE-lined rod ends. This provides a balance of vibration isolation, controlled deflection, and maximum articulation for excellent responsiveness.
• Complete System Approach: Unlike budget lifts that just use spacers, this is a true system. Shocks, springs, track bars, steering components, and brake line brackets are all included and engineered to work together harmoniously.

How to Use ICON, 4.5 Lift, Stage 4 Suspension System, Compatible with 2007-18 JK Wrangler, K24004: Complete Guide

Installing and setting up this system is a serious job, but following the correct steps ensures you get the best performance and longevity. Here is our step-by-step guide based on actual installation experience.

Step 1: Initial Setup and Installation

This is a substantial installation that requires advanced mechanical skills, a good set of tools, and a safe working area. Begin by safely lifting the vehicle and supporting it on jack stands. Remove the wheels and tires. The process involves unbolting the factory shocks, springs, track bars, and sway bar links. You will then install the new dual-rate coil springs and shocks. The high-steer flip kit requires removing the steering knuckles to install the new taper adapters and steering arms. Follow the ICON instructions meticulously. Torque all fasteners to the specified values.

Step 2: First-Time User Guide

After installation, the first drive is crucial. You must perform a system check. Turn the steering wheel lock-to-lock to ensure there is no binding or contact between the tires and the new suspension components. Measure the ride height at all four corners to ensure the vehicle is sitting level. If you bought the ICON stage 4 lift system, you will likely need to adjust the track bars to center the axles. Drive slowly in a parking lot listening for any unusual noises. Check your brake lines to ensure they have enough slack with the new lift height.

Step 3: Core Functions and Daily Use

In daily use, you will notice the refined ride quality immediately. The dual-rate springs absorb potholes and expansion joints with surprising compliance for a lifted vehicle. On the highway, the system tracks straight with minimal steering correction needed. The high-steer kit eliminates bump steer significantly. For off-road use, air down your tires and select 4-Low. The articulation provided by this system is impressive, allowing each wheel to maintain contact with the trail. You can drive over rocks and logs with confidence.

Step 4: Advanced Techniques

For experienced off-roaders, the system allows for fine-tuning. You can adjust the spring preload on the ICON shocks (if equipped with a reservoir) to tune for different loads. The adjustable track bars can be tweaked to compensate for any slight axle shift after heavy use. When rock crawling, use the improved ground clearance from the high-steer kit to your advantage, as you no longer have a vulnerable drop pitman arm hanging low.

Step 5: Maintenance and Care

Regular maintenance is simple. After every off-road trip, rinse the suspension components with a hose to remove mud and debris that can cause corrosion. Inspect all bushings and rod ends for wear or damage. Periodically check the torque on critical fasteners, especially the track bar bolts and steering linkage. The dual-rate springs need no maintenance, which is a major advantage of deciding to buy ICON stage 4 lift system.

Step 6: Troubleshooting Common Issues

If you experience a clunking noise, check that all bolts are torqued to spec and that the sway bar links are properly installed. If the vehicle pulls to one side, the track bars may need adjustment to center the axles. If the ride feels harsh, ensure the shocks are not set to full stiff. For detailed troubleshooting, refer to our lift kit common problems guide.

Performance & Real-World Testing

Testing Methodology

We tested the ICON Stage 4 system on a 2015 Jeep Wrangler Unlimited Rubicon over a four-week period. Our testing included 500 miles of daily highway commuting, 100 miles of winding mountain roads, and two full days of rock crawling and trail running at a local off-road park. We evaluated ride quality, articulation, stability, and noise levels.

Performance Metrics

On-road, the ICON system delivers a significantly improved ride compared to the stock Rubicon suspension. Highway stability is excellent at speeds up to 75 mph with 35-inch tires. There is minimal body roll in corners, and bump steer is virtually eliminated thanks to the high-steer kit. Off-road, the articulation is phenomenal. We measured over 20 inches of wheel travel at each corner. The dual-rate springs work perfectly, providing a supple initial stroke over small rocks and then firming up to prevent bottoming out on larger obstacles.

Real-World Scenarios

On a technical rock crawl, the high-steer kit proved its worth by allowing us to clear obstacles that would have snagged a standard drop pitman arm. The adjustable track bars made it easy to keep the axles perfectly centered after a day of hard use. In deep sand, the controlled compression and rebound of the shocks kept the tires planted and the vehicle stable at speed.

Claims vs. Reality

ICON claims guaranteed no sag on the dual-rate springs. After four weeks of use and multiple hard off-road trips, we measured no change in ride height. The high-steer kit delivered on its promise of improved steering geometry and ground clearance. The ride quality claim of being comfortable for daily driving is accurate. After extensive use, we believe this product lives up to its premium reputation, confirming why many enthusiasts should buy ICON stage 4 lift system.

Expert Tips for Maximum Value

Tip #1: Professional Installation is Worth the Cost

Given the complexity of the high-steer kit and the precise requirements for track bar adjustment, we strongly recommend professional installation. A good shop will ensure everything is torqued correctly and aligned properly, saving you headaches and potential damage. This ensures you get the most out of your investment when you buy ICON stage 4 lift system.

Tip #2: Pair with High-Quality Tires

This lift is designed for 35-inch to 37-inch tires. Do not skimp on tires. A quality all-terrain or mud-terrain tire will maximize the performance and ride quality of the ICON system. The suspension can handle the weight and size, but the tire quality determines traction and noise.

Tip #3: Upgrade Your Steering Damper

While the high-steer kit improves steering, an upgraded aftermarket steering damper, like the one from Fox or ICON, can further reduce steering wheel kick and improve control on rough terrain. This is a relatively inexpensive upgrade that complements the system well.

Tip #4: Ensure Proper Gearing

With 35-inch or larger tires, your JK Wrangler will likely need re-gearing to restore acceleration and drivability. Factor in the cost of re-gearing your differentials when budgeting for this lift. A properly geared JK will perform dramatically better off-road and on the highway.

Tip #5: Use Anti-Seize on All Threads

During installation, apply a liberal amount of anti-seize compound to all bolt threads, especially those on the track bars and steering components. This will make future adjustments and maintenance significantly easier and prevent seized fasteners.

Tip #6: Get a Professional Alignment

After installation and initial track bar adjustment, take your Jeep to a shop that specializes in lifted vehicles for a full front-end alignment. Proper caster, camber, and toe settings are crucial for tire longevity and highway stability.

Tip #7: Join an Off-Road Community

Connect with other JK owners who have this system. Online forums and local clubs are invaluable resources for sharing tuning tips, trail recommendations, and maintenance advice. You can learn a lot from the collective experience of others who chose to buy ICON stage 4 lift system.

Common Mistakes to Avoid

1. Mistake: Not torquing the high-steer knuckle bolts to the correct specification. Solution: Use a torque wrench. Overtorquing can warp the knuckle, and undertorquing can lead to catastrophic steering failure. This is critical for safety.
2. Mistake: Forgetting to adjust the drag link after installing the high-steer kit. Solution: The drag link length must be adjusted to center the steering wheel. Failure to do so will result in the steering wheel being off-center and potential handling issues.
3. Mistake: Not cycling the suspension before tightening all bolts. Solution: Tighten all control arm, track bar, and sway bar link bolts with the suspension supporting the vehicle’s weight on level ground. Tightening them when the suspension is hanging will bind the bushings and cause premature failure.
4. Mistake: Using an impact wrench on all fasteners. Solution: Use a torque wrench for final tightening. Impact wrenches can easily overtorque fasteners on aluminum components, causing damage. Hand-tighten and then use a torque wrench.
5. Mistake: Assuming the track bars are “set-and-forget.” Solution: Check the track bar adjustment after the first off-road trip and every few thousand miles. Axles can shift slightly over time, and a quick adjustment will keep your Jeep tracking straight.

Pricing & Where to Buy

The current price for the ICON, 4.5 Lift, Stage 4 Suspension System is $7,034.02 USD. This places it firmly in the premium category of lift kits.

Will this lift void my Jeep warranty?

In most cases, an aftermarket lift will not void the entire vehicle warranty. However, the Magnuson-Moss Warranty Act protects consumers. A dealer can only deny warranty coverage for a specific issue if they can prove the aftermarket part caused the damage. For example, if a factory shock fails, the dealer could argue the lift kit contributed.

How long does installation take?

For a professional shop with experience, expect 8-12 hours of labor. For a skilled DIY mechanic working at home, plan for a full weekend or two full days. The high-steer kit and track bar adjustment add considerable time compared to simpler lifts.
