4.5 Inch X-Factor No Limits Mid-Arm Suspension System for Jeep Wrangler JLU 4XE Models Comp System Stage 2 Rock Krawler
Description
Rock Krawler 4.5 X-Factor Coilover No-Limits Mid-Arm Suspension System for Jeep Wrangler JLU (4XE Models)
The Rock Krawler 4.5 X-Factor Coilover Mid-Arm 4XE System is specifically designed for Sport and Sahara owners who want a complete system, bolt-in installation, and the best articulation of any mid-arm kit on the market. The term No-Limits comes from the inclusion of our front sway bar links specifically designed for use with the factory electronic sway bar disconnect feature found standard in your Rubicon Wrangler!
The sway bar links themselves come with factory sized hardware, a CNC machined billet aluminum center section, and Made in USA heim joints from FK bearing, once installed, just press the button and hit the rocks! 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 JL 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 JL's caster and pinion angle front and rear.
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.
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. There are two options for the Comp Systems you can choose from.
The standard or Stage 1 System features 2 5/8 RRD Racing Coilovers w/Remote Reservoirs up front paired with matching 2 5/8 RRD Racing Shocks w/Remote Reservoirs in the rear for a well tuned package. Or you can opt for the Stage 2 Comp System which will include Fast CD (Compression Dampening) Adjusters on the coilovers and rear shocks 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!
