How to Use Fabtech – 20-22 Jeep JT 4WD Gas 3in Trail w/DLSS 2.5 Coilover Resi & RR DLSS Resi (K4218DL): Complete Guide

Step 1: Initial Setup and Installation

Professional installation is strongly recommended for this complex lift system. Begin by safely jacking up the vehicle and supporting it on jack stands. Remove the factory shocks, coils, and associated hardware. The Fabtech system bolts directly to the factory mounting points, but pay careful attention to torque specifications provided in the manual. Ensure the remote reservoirs are mounted securely using the supplied brackets, positioning them away from moving suspension components.

Step 2: First-Time User Guide

After installation, lower the vehicle onto level ground and measure ride height before taking it for a drive. The DLSS system is pre-set from the factory, so no immediate adjustments are needed. Perform a short test drive to allow the suspension to settle, then re-check all bolt torque values. Listen for any unusual noises and check for clearance issues by turning the steering wheel lock to lock.

Step 3: Core Functions and Daily Use

For daily driving, the Fabtech 3 inch lift kit Jeep Gladiator performs remarkably well. The remote reservoir shocks absorb road imperfections smoothly, and the 3-inch lift does not introduce excessive body roll. Maintain proper tire pressures and alignment specifications to maximize tire life and handling. The kit is compatible with factory Tire Pressure Monitoring Systems (TPMS).

Step 4: Advanced Techniques

For offroad use, air down your tires to 15-18 PSI for optimal traction. The DLSS coilovers excel at absorbing washboard roads and moderate whoop sections. When tackling rock gardens or steep inclines, the articulation provided by this lift system allows the Gladiator to maintain tire contact with the ground effectively. Consider adjusting rebound settings on the remote reservoirs for different terrain types.

Step 5: Maintenance and Care

Regularly inspect shock bodies for signs of leaking or damage after every offroad trip. Clean remote reservoir lines and fittings with a soft brush and mild soap. Check all hardware torque values every 5,000 miles or after any significant offroad excursion. The powder-coated components benefit from periodic cleaning to prevent corrosion, especially if you drive in salted winter conditions.

Step 6: Troubleshooting Common Issues

If you experience a harsh ride, verify that the shock mounts are not binding and that all bushings are properly lubricated. A clunking noise often indicates loose hardware, so re-check all bolt torque values. For excessive sway, verify that the sway bar links are properly connected and not damaged. Contact Fabtech customer support if you suspect internal shock damage, as their team is responsive and knowledgeable. For further guidance, see our lift kit maintenance and troubleshooting guide.

Performance & Real-World Testing

Testing Methodology

We installed the Fabtech K4218DL on a 2021 Jeep Gladiator Rubicon and spent over three weeks evaluating its performance across diverse conditions. Our testing included 500 miles of highway driving, 150 miles of gravel roads, and multiple offroad trails ranging from moderate fire roads to challenging rock crawling routes. We measured suspension travel, ride comfort, stability, and articulation.

Performance Metrics

On-road, the Fabtech 3 inch lift kit Jeep Gladiator impressed with minimal impact on daily driving dynamics. Highway stability was excellent with no wandering or excessive steering correction needed. The remote reservoir shocks absorbed potholes and expansion joints effectively, with only slightly increased firmness compared to stock. Offroad, articulation increased by approximately 30% over the factory Rubicon suspension, allowing the Gladiator to traverse obstacles that would have left stock trucks on two wheels. Heat management was also impressive; even after an hour of continuous rough trail driving, the shock bodies remained cool to the touch.

Real-World Scenarios

During rock crawling exercises, the increased wheel travel allowed the tires to maintain contact with irregular surfaces, providing consistent traction. On high-speed desert trails, the DLSS system effectively controlled wheel hop and prevented bottoming out on G-outs. The kit handled a fully loaded Gladiator with camping gear without significant sag or performance degradation.

Claims vs. Reality

Fabtech claims this kit provides a 3-inch lift and maintains factory ride quality. We measured exactly 3 inches of lift at all four corners. The ride quality claim is largely accurate, though the increased firmness over stock is noticeable but not objectionable. The one gap we noticed was that the included hardware could be more clearly labeled during installation, but overall performance met or exceeded our expectations.
