Rock Krawler 4.5 X-Factor Mid-Arm Suspension System for Jeep Wrangler JKThe Rock Krawler Suspension 4.5 X-Factor Mid-Arm System is specifically designed for Wrangler 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 JK 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 JK's caster and pinion angle front and rear.Driving you home with the most comfortable ride possible in a Wrangler, are our Triple-Rate 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 has a very controlled reaction to bumps, rocks, sand, mud and whatever else you can manage to throw at them! All Rock Krawler JK systems include correction pads that reduce the spring bow inherent in the factory setup.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. When we design a system, our goal is to provide you with the most comprehensive solution and the best geometry, install exceptional value, and be the foundation for every adventure whether it be on the Street, in tow or down a trail!Thank you for considering Rock Krawler Suspension.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 Long-Arm System Best Technical Support In The Industry Jeep Remains Level On All 4 Corners Lifetime Warranty Coverage System Includes: (4) Triple-rate Coil Springs (2) Front High Clearance Adjustable Lower Control Arms (2) Front Adjustable Upper Control Arms (1) Adjustable Front Track Bar (1) pro-x Top Mount Drag Link (2) Quick Disconnect Front Sway Bar Links (2) Rear High Clearance Adjustable Lower Control Arms (2) Rear Adjustable Upper Control Arms (2) Rear Spring Pads (2) Adjustable Rear Sway Bar Links (1) Bolt-on Rear Track Bar Relocation Bracket (1) Rear Track Bar (1) Front and Rear Extended Brake Line Kit (Depending on shock package chosen) Bump Stops Are Included With All Shock Options If you choose no shocks, bump stops can be purchased separately - RK07123 Shock Information: All RRD Shocks and Coilovers are designed and built in-house Generic Front Shock Length - 18.5 inch Collapsed/29 inch Maximum Extended Generic Rear Shock Length - 17.3 inch Collapsed/28.31 inch Maximum Extended RRD 2.25 IFP Shocks 2.25 inch O.
