Overview

Rock Krawler X-Factor Series Mid-Arm No Limits Suspension Lift Kits

Rock Krawler X-Factor Series No Limits mid-arm suspension systems are engineered for Jeep JL/JLU models that need a bolt-in system with excellent street manners and the kind of articulation you expect when the trail gets technical. The "No Limits" name comes from the included front sway bar links designed to retain full function of the factory electronic sway bar disconnect found on select models. Built around their X-Factor adjustable control arms and triple-rate coil springs, these kits reduce factory bind through high-misalignment joints and provide the adjustability needed to precisely dial-in caster and pinion angle, delivering confident highway behavior while staying compliant and controlled off-road. Get a lift system designed to flex hard on the trail, then track straight on the drive home when you order the Rock Krawler X-Factor Series mid-arm No Limits suspension lift kit best suited for your application.

More product features, items, and notes include:

* Choose the shock package that fits your build: no shocks, Bilstein shocks (B51 suffixes), or their in-house RRD 2.25 in. IFP shocks (S1 suffixes); availability varies by application
* Listed components vary slightly by shock package
* Triple-rate coil springs for improved ride quality versus typical linear-rate springs, while maintaining proper free length for articulation
* No Limits front sway bar links with CNC-machined billet aluminum center sections, factory-size hardware, and FK Bearing Heim joints
* Adjustable X-Factor upper and lower control arms (front and rear) with high misalignment up to 95 degrees when paired with their joint systems, helping reduce binding and improve articulation
* Adventure Series joints at frame-side connections and Pro Krawler joints at axle-side connections, reducing bind compared to OE-style arms
* Track bar geometry corrections (front and rear) plus adjustable track bars/relocation hardware to re-center axles and maintain stable on-road handling after lifting
* Improved rear roll center, spring correction seats, vehicle lean correction, and adjustable front track bars
* System architecture designed to be a base for future suspension expansion, including long arm upgrades, if desired
* Shock-equipped kits feature bump stops; shock-less versions require bump stops to be purchased separately
* Tire size can affect wheel backspace recommendations and require trimming of full OE-style fenders
* Bump stop height of 3 in. recommended for most builds (application dependent)
* Rear lift height adjustments recommended for spare‑delete or heavily up-fitted rear builds (typically done with one-inch taller or shorter rear coil springs)
* New front driveshaft recommended if you plan to off-road routinely
* Welding the rear cradle for use with 37 in. and larger tires highly recommended
* All lift heights based on Rubicon models for standard style build (front bumper and winch, rear bumper, and full-size spare)
