Rock Krawler 3. 5 X Factor X2 Flat Belly 5 Stretch Coilover Long Arm Suspension System For Jeep Wrangler TJ The Rock Krawler Suspension 3. 5 X Factor X2 Flat Belly 5 Stretch Coilover Long Arm System is a massive evolution to long arm systems for TJ Wranglers. This incredible system allows you to add a full, weld in Coilover system front suspension, and keep a traditional spring and shock rear setup. In addition, this system allows a 5 rear stretch via longer upper and lower control arms. We led the way with the Revolutionary X Factor Long Arm design featuring the industry's first Independent 3 Link Front and Triangulated 4 Link Rear Suspension Design Ever! The X Factor Long Arm design has stood the test of time and has been mimicked by many other companies in its 20+ year history! How do we as an industry leader blow something out of the water that has done so well for so long? The answer is the all new TJ X Factor X2 Flat Belly Long Arm Systems. The industry's only full flat belly long arm system where all the arms tuck up right inside the frame! The X Factor X2 geometry is enhanced above and beyond our old X Factor Long Arm, adding more double triangulation to the rear for even better stability. The ride quality has also improved by adding our Adventure Series joints to the frame side of the lower control arms and thus reducing overall system maintenance. The newer Pro X Krawler Joints with the one piece Basf thermo elastomer material round out the joints used in the system for an unbelievable 95 degrees of misalignment or more, available on each and every control arm in the system. Of course, these systems come with our technologically advanced and tuned Triple Rate Coils Front and Rear. No one can beat this combination of cross over angles, ground clearance gains, ride quality, tuned suspension performance, durability and our abuse proof lifetime warranty on all hard parts. The Rock Krawler X Factor X2 Flat Belly Long Arm System is paving the way for future TJ Builds. The Comp System (Front Coilovers w Rear Coil Combination) is ideal for those that want the adjustability and performance of coilover racing shocks up front, but still want to use their Wrangler to carry small loads or tow small trailers. The Trail Runner System (Front and Rear Coilover Combination) is ideal for those that want the adjustability and performance of coilover racing shocks at all 4 corners. This combination maximizes the off road ability of your Wrangler and comes well tuned for the street. Rear coilovers perform amazing off road, but do not take changes in loading conditions too well so towing or adding a lot of weight to the bed area is not optimal for rear coilovers. The standard or Stage 1 System features 2 5 8 RRD Racing Coilovers w Remote Reservoirs front and for a well tuned package. Or you can opt for the Stage 2 Trail Runner System which will include Fast CD (Compression Dampening) Adjusters on the coilovers for an even greater level of tuneability. Like all of our systems, amazingly tuned ride and handling is our number one priority! It is no different with our coilover systems. Coilovers add another level of tuneability for the vehicle owner to further enhance the ride, handling and off road performance to their liking. Install exceptional value, and be the foundation for every adventure whether it be on the Street or on the Trail with a Rock Krawler Coilover Suspension System!
