This is the Rubicon version of the Adventure-X mid-arm kit. The No Limits name comes from the front sway bar links, which are built to work with the factory electronic sway bar disconnect on your Rubicon Gladiator, so you keep pressing the button and hitting the rocks. Add a 3 inch lift, eight adjustable control arms with service-free Adventure Series joints, and a complete bolt-in install, and it is a very straightforward way to get a Rubicon JT working better on and off the road.
What is in the kit
- 4 coil springs: triple-rate in the front, quad-rate in the rear
- 2 front high clearance adjustable lower control arms and 2 front adjustable upper control arms
- 2 rear high clearance adjustable lower control arms and 2 rear adjustable upper control arms
- Front and rear spring pads
- Adjustable front track bar
- 2 No Limits front sway bar links and 2 adjustable rear sway bar links
- Bolt-on rear track bar relocation bracket
Shocks depend on the package you pick below. The coilover packages also include shock towers and brackets, plus rear quad-rate coil springs and spring correction seats in the Comp System.
Why this system
- No Limits front sway bar links are made for the factory electronic sway bar disconnect found on the Rubicon. They have factory-sized hardware, a CNC machined billet aluminum center section and Made in USA heim joints from FK Bearing.
- Eight adjustable control arms with Adventure Series joints give about 70 degrees of total misalignment at the frame and axle.
- Adjustable arms let you tune caster and pinion angle front and rear.
- Triple-rate front and quad-rate rear coils, with correction pads that remove the spring bow found in the factory setup.
- Track bar geometry corrections front and rear so the axles sit centered and on-road handling is not compromised.
- Service-free joints, complete bolt-in system, and an upgrade path to Rock Krawler's long-arm system.
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, Rubicon 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: Rock Krawler recommends 4.5 inches of backspacing for 37 inch tires and 3.5 inches for 40 inch tires. With full factory fenders it lists 37 or 38 inch tall tires; with trimmed or high-lined fenders, 40 inch. 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).
Rock Krawler lists lifetime warranty coverage on this system, and lead times of about 1 to 2 weeks on mid-arm kits, counted in business days from the order date.
