Rock Krawler 3.5 Inch X-Factor X2 No Limits Long Arm System - Wrangler JL 2-Door
JL35X2NL-2
Take the X-Factor X2 long arm and add the front sway bar links that work with the factory electronic sway bar disconnect on a Rubicon, and you get the No Limits version. It's built for the 2018 and newer Jeep Wrangler JL (2-door) owner who wants hard-core rock crawling capability, an independent 3-link layout front and rear, and the convenience of pressing a button to free up the front axle.

Why this system
- Independent 3-link long arm rear with X2 geometry: adjustable anti-squat plus a higher rear instant center and roll center, so the Jeep stays settled on pavement and on the trail.
- The X2 axle bracket system gains 4.5 inches of clearance under the rear axle, and the rear upper shock relocation brackets keep your full shock travel.
- High-clearance long arms front and rear for articulation and rock clearance.
- Maintenance-free Adventure Series joints at the frame connections cut down grease points, soak up vibration and allow proper misalignment off-road.
- Heat Shield thermal barrier products, like OEM uses, protect the front control arm joints at the frame.
- Triple-rate coil springs with correction seats give a comfortable street ride, and the coils stay firmly seated through articulation as long as a proper-length shock is installed.
- Double-adjustable upper control arms step the factory hardware up to 14mm with a 2 3/8 inch mounting width and 1 inch Pro Krawler joints at each end, built from solid chromoly steel.
- No Limits: front sway bar links made for the factory electronic sway bar disconnect on Rubicon models, with factory-size hardware, a CNC-machined billet aluminum center section and Made in USA heim joints from FK Bearing. Install them, press the button and hit the rocks.
- Lifetime warranty coverage.
Pick your package
- Base System (No Shocks). The kit as listed above with no shocks, for the builder who already has shocks picked out. Bump stops come with every shock option; with this one they're ordered separately.
- Bilstein 5100 Shocks. The kit plus Bilstein 5100 shocks. Rock Krawler calls them maintenance free and a great pairing with its multi-rate coil springs.
- Stage 1 (RRD 2.25 inch IFP shocks). Rock Krawler's in-house shock: a 2.25 inch hard anodized fluted aluminum body with the cooling surface of a 2.5 inch shock, a 3/4 inch hard chrome stainless steel shaft, billet aluminum valving and dual DU shaft bearings. Serviceable, rebuildable and revalveable.
- Coilover Comp System, Stage 1. Coilovers up front, coil springs and a shock in the rear: 2.625 inch RRD racing coilovers with remote reservoirs up front (12 inches of travel, about 13.3 inches of front axle travel) and matching 2.625 inch RRD racing shocks in the rear (11.5 inches of travel, about 12.8 inches of rear axle travel). Rock Krawler pitches it at owners who want coilover adjustability but still carry small loads or tow small trailers. Includes (2) triple-rate coil springs and (2) correction seats.
- Coilover Comp System, Stage 2 (Fast CD). The same Comp System layout and travel as Stage 1, with Fast CD (compression damping) adjusters on the coilovers and the rear shocks for more tuning range.
- Coilover Trail Runner, Stage 1. Coilovers at all four corners: 2.625 inch RRD racing coilovers with remote reservoirs front and rear (12 inches of front travel, 11 inches in the rear). Rock Krawler notes rear coilovers don't take changing loads as well, so heavy towing or a loaded bed isn't ideal.
- Coilover Trail Runner, Stage 2 (Fast CD). The Trail Runner layout with Fast CD (compression damping) adjusters on the coilovers for even more tuneability.
Fitment and what else you'll need
Fits the 2018 and newer Jeep Wrangler JL (2-door): gas models with the 2.0L turbo four-cylinder, the 3.6L Pentastar V6 or the 3.6L Pentastar with eTorque.
Rock Krawler bases all lift heights on Rubicon models in a standard build (front bumper and winch, rear bumper and full-size spare). If you delete the spare, drop 1 inch of rear coil lift height; for an overland or heavily loaded rear build, go up 1 inch.
- Rubicon: 37 inch tall tires want 4.5 inches of backspacing and 40 inch tall tires want 3.5 inches. With full OEM fenders, 37 or 38 inch tires fit; with trimmed or high-lined fenders, 40 inch tires fit (3 inch bump stop height recommended).
- Requires welding of the front and rear long arm mounts.
- Requires removing the OEM frame side lower and upper front and rear control arm mounts, and the OEM axle side rear lower control arm and track bar mounts.
- Requires modifying the OEM rear shock mounts and welding on the raised rear upper shock mounts.
- Front 3-link suspension systems require aftermarket front axles that don't have F.A.D.
- Rock Krawler recommends a new front C.V. driveshaft for any front shock with a max extended length over 29 inches.
- Limiting straps are recommended once the vehicle is set up, to avoid over-extending suspension components.
Rock Krawler lists lifetime warranty coverage on this system. Posted lead times from Rock Krawler, in business days from order: mid arm kits 1 to 2 weeks, long arm kits 3 to 4 weeks, 2.25 inch shocks 1 to 2 weeks and 2.625 inch shocks or coilovers 3 to 4 weeks.
