4.5 Inch X-Factor X2 Coilover No Limits Long-Arm Suspension System for Jeep Wrangler JLU Gas Models Trail Runner System Stage 2 Rock Krawler

Rock Krawler 4.5 X-Factor X2 Coilover No-Limits Long-Arm Suspension System for Jeep Wrangler JLU (Gas Models)

The Rock Krawler 4.5 X - Factor X2 Coilover Long-Arm System is specifically designed for Wrangler owners who want to push their vehicle to its limits with hard core rock crawling. 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! The Rock Krawler X2 Long-Arm System features an Independent 3 link design front & rear for maximum articulation and off-road performance.

Our proprietary design utilizes a double adjustable front and rear upper control arm that upsizes the factory hardware to 14mm, 2 3/8 mounting width and 1 Pro Krawler joints at each end. The arm itself is a chromoly solid steel arm meant to carry all the forces of the suspension.

The rear suspension provides adjustable anti-squat with X2 rear suspension geometry with enhanced rear instant center (s) and rear roll center (s). As you drive the highways or the trails, the system feels stable, safe and strong whether you are running the stock drivetrain or pushing high horsepower through the chassis.

We have built the X-Factor X2 system to be the toughest 3-Link setup on the market. At the frame connections of the lower control arms, our Adventure Series maintenance-free joint is used to cut down on the amount of grease points, and provide excellent vibration absorption and proper joint misalignment when off-road.

The combination of high clearance long arms and 3 link suspension geometry lets you dominate the trails.

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.

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!
