ROCK KRAWLER 4.5IN X FACTOR COIL OVER MID ARM LIFT KIT

The Rock Krawler Suspension JT 4.5 inch X-Factor Diesel Mid-Arm System is specifically designed for Sport/Overland owners who want a complete system, bolt-in installation, and the best articulation of any MID-ARM kit on the market. Our system proves its durability and off-road performance every time you hit the streets or trail! Our industry leading, X-Factor Series, adjustable upper and lower control arms offer a total of 95 degrees of misalignment when paired with our Pro-X Krawler Joints and Adventure Series joints. The inherent bind in a factory JT control arm is greatly reduced. Our maintenance free "Adventure Series" joints are found in your front and rear control arms at the frame connection, while our "PRO Krawler Joints" tie in your axle connections. With so much adjustability, it allows you to precision tune the JT's caster and pinion angle front and rear. Driving you home with the most comfortable ride possible in a Gladiator, are our TRIPLE RATE front coils/QUAD RATE rear coils. All 4 coils work together to achieve excellent on-road comfort that we feel is better than the OEM linear rate springs. The coil itself is built with the proper "Free-length" for off-road articulation and stays firmly seated in the coil bucket (as long as a proper length shock is installed), and overall a very controlled reaction to bumps, rocks, sand, mud and whatever else you can manage to throw at them! All Rock Krawler JL systems include correction pads that reduce the spring bow inherent in the factory set up. The provided track bar geometry corrections, both front and rear, lets you perfectly center the axles so there is no compromise in on road handling.   System Benefits: Complete bolt in system Excellent highway ride and handling The best off-road ability of all Mid Arm Systems Improved rear roll center Tuned Triple Rate Coils Spring Correction Seats Vehicle lean correction Upgradable to RK Longarm System Best Technical support in the industry Jeep remains level on all 4 corners Lifetime Warranty Coverage   Wheel Fitment: Sport and Overland Wheel Fitment Recommendations 37”/38” Tall Tires - Recommend 3.5” of Back Spacing Rubicon Fitment Recommendations 37” Tall Tires – Recommend 4.5” of Back Spacing 40” Tall Tires – Recommend 3.5” of Back Spacing   Tire Fitment: Sport and Overland with Full OEM Fenders 37” Tall Tires (3” Bump Stop Height Recommended) Sport and Overland with Trimmed or High Lined OEM Fenders 38” Tall Tires (3” Bump Stop Height Recommended) Rubicon with Full OEM Fenders 37”/38” Tall Tires (3” Bump Stop Height Recommended) Rubicon with Trimmed or High Lined OEM Fenders 40” Tall Tires (3” Bump Stop Height Recommended)   General Notes: All lift heights based on Rubicon models for standard style build (i.e. front bumper and winch, rear bumper and full size spare). If building with a spare delete, we recommend dropping 1” in coil lift height for the rear.
