X-Factor X2 is the hard-core rock crawling version of Rock Krawler's long-arm kit. It runs an independent 3-link design front and rear, with double adjustable upper control arms on both ends and chromoly solid steel arms built to carry the loads. Rock Krawler calls it the toughest 3-link setup on the market. It is a weld-in kit for Sport, Overland and Mojave Gladiators, in gas or diesel.

Why this system
- Independent 3-link front and rear for maximum articulation and off-road performance.
- Double adjustable front and rear upper control arms upsize the factory hardware to 14mm with a 2 3/8 inch mounting width and 1 inch Pro Krawler joints at each end. The arm itself is chromoly solid steel.
- Adventure Series maintenance-free joints at the lower control arm frame connections cut grease points and absorb vibration.
- X2 rear geometry gives adjustable anti-squat and enhanced rear instant center and roll center, and the X2 axle bracket system gains 4.5 inches of rear clearance.
- Stays stable on the highway and the trail with a stock drivetrain or with high horsepower going through the chassis.
- Tuned triple-rate coils with spring correction seats front and rear.
Pick your package
Pick gas or diesel first, since the diesel kit is built specifically for the 3.0L Eco-Diesel. Then choose how you want to handle shocks.
- Base System (No Shocks). The full kit minus shocks, for anyone who already has a shock setup picked out. Bump stops ship with every shock package, so here they are a separate buy (Rock Krawler part RK07464). Rock Krawler's generic shock lengths: front 17.5 inches collapsed and 29.5 extended, rear 17 collapsed and 28 extended.
- Bilstein 5100 Shocks. Rock Krawler pairs these with its multi-rate coils. Maintenance free, bump stops included.
- Stage 1 (RRD 2.25 IFP Shocks). Rock Krawler's own RRD 2.25 inch IFP shocks, built in-house: hard anodized fluted aluminum body, 3/4 inch 17-4 PH stainless shaft, billet aluminum valving and dual DU shaft bearings. Serviceable, rebuildable and revalveable. Bump stops included.
- Comp System. Coilovers up front, coil springs still in the rear. It uses 2 5/8 inch RRD racing coilovers with remote reservoirs in the front and matching 2 5/8 inch RRD shocks with remote reservoirs in the rear, good for 13.3 inches of front axle travel and 13.1 inches of rear axle travel. Rock Krawler points this one at people who still carry small loads or tow small trailers.
- Comp System with Fast CD Adjusters. Same layout as the Comp System, with Fast CD (compression dampening) adjusters on the front coilovers and rear shocks for more tuning.
- Trail Runner System. Coilovers at all four corners, with 13.3 inches of front axle travel and 13.75 inches in the rear. Rock Krawler notes rear coilovers do not handle changing loads well, so towing or hauling a lot of weight in the bed is not ideal.
- Trail Runner System with Fast CD Adjusters. The Trail Runner layout with Fast CD (compression dampening) adjusters added to the coilovers.
Coilover packages need some fabrication. Rock Krawler lists removing the factory shock mount on the frame, removing the factory shock and spring mount on the axle, and welding the new coilover mount to the axle.
Fitment and what else you will need
- Fits the 2020+ Jeep Gladiator JT, 4-door, 4WD, Sport, Overland and Mojave trim. Engine: gas (3.6L Pentastar V6) and diesel (3.0L Eco-Diesel).
- Lift heights are based on a Rubicon with a standard build (front bumper and winch, rear bumper and full-size spare). With a spare delete, drop 1 inch of rear coil lift height; with a heavily up-fitted or overland-style rear, go up 1 inch.
- Wheels and tires: on Sport and Overland, 3.5 inches of backspacing, with 37 inch tires under full fenders or 38 inch with trimmed or high-lined fenders. On Mojave, 4.5 inches of backspacing for 37 inch tires and 3.5 inches for 40 inch tires (37 or 38 inch under full fenders, 40 inch trimmed). A 3 inch bump stop height is recommended.
- Rock Krawler recommends a new front driveshaft if you plan to off-road routinely (it names Adam's Driveshaft, Tom Woods and J.E. Reel).
- This is a weld-in kit. Rock Krawler lists welding of the front and rear long-arm frame-side mounts, removal of the factory frame-side lower front control arm mounts, removal of the frame-side front and rear upper control arm mounts and removal of the axle-side track bar mount.
- Rock Krawler notes that front 3-link suspension systems require aftermarket front axles that do not have F.A.D.
- Rock Krawler recommends limiting straps to avoid over-extending suspension components after the vehicle is set up.
- An optional Pro-X cradle is available for Dynatrac XD60 rear axles (RK08078) and Ultimate Dana 60 rear axles (RK08068).
Rock Krawler lists lifetime warranty coverage on this system, and lead times of about 3 to 4 weeks on long-arm kits, counted in business days from the order date.
