Introducing the enhanced 69-6042 4" Terrain Flex MAX lift kit for Jeep Gladiator enthusiasts. Building upon the popularity of our 4" Terrain Flex lift kit, this upgraded version offers several improvements for discerning customers. Key enhancements include linear rate rear coil springs perfectly matched with the front springs, ensuring a comfortable ride and exceptional articulation. The addition of a heavy-duty rear track bar bracket enhances rear axle alignment and overall suspension geometry performance. The 69-6042 lift kit elevates your Jeep Gladiator to a higher stance, accommodating up to 37" tall tires. Extensive engineering and rigorous testing, including interstate travel and extreme rock crawling adventures, have fine-tuned this system for a harmonious blend of on-road civility and off-road prowess. The kit features 4" lift replacement front and rear springs with a larger wire diameter, accommodating heavy aftermarket accessories such as winches and steel bumpers. Further enhancing performance, we introduce beefier .188 wall lower control arms with Terrain Control Technology (TCT) non-bonded, maintenance-free bushings, aiding in caster geometry while excelling both on and off-road. Longer sway bar end links, bump stop extensions, a heavy-duty rear track bar bracket, and an adjustable front track bar contribute to optimizing your Gladiator's ride and flexing capabilities. To complete the ultimate Terrain Flex Lift Kit, we've partnered with Falcon to include Falcon 2.1 mono tube performance shocks designed specifically for the JT Gladiator. The result is a remarkable 4" lift system that delivers improved on-road comfort and exceptional off-road performance. Please note that vehicles with adaptive cruise control will require zero-point calibration at the dealership post-installation, and this kit is not compatible with Wrangler or Gladiator optional powertrains, including the 3.0L Diesel, Rubicon 392, and 4xe editions.
