This one is for Rubicon Gladiator owners who want aluminum arms. All eight control arms are solid 7075 aluminum, and the No Limits front sway bar links are made to work with the factory electronic sway bar disconnect. It lifts the truck 3 inches, bolts in, and carries the full X-Factor articulation.
What is in the kit
- 4 coil springs: triple-rate in the front, quad-rate in the rear
- 2 front 7075 aluminum adjustable lower control arms and 2 front 7075 aluminum adjustable upper control arms
- 2 rear 7075 aluminum adjustable lower control arms and 2 rear 7075 aluminum adjustable upper control arms
- Front and rear spring pads
- Adjustable front track bar

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
- All eight arms are solid 7075 aluminum with the X-Factor benefits built in.
- No Limits links have factory-sized hardware, a CNC machined billet aluminum center section and Made in USA heim joints.
- About 95 degrees of total misalignment with Pro-X Krawler joints at the axle.
- Adjustable arms for caster and pinion angle tuning front and rear.
- Triple-rate and quad-rate coils with spring correction pads.
- Complete bolt-in system with 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.
