When prepping any Jeep for off-road adventures, springs, shocks, and lift kits are commonly the first area of focus. While those are ideal means to improve on your overlander’s control when leaving the pavement, it’s the control arms that are the real game-changer in terms of off-road handling. They’re the unsung heroes of the suspension system, correcting suspension geometry, unlocking articulation, and ensuring your Jeep rides right, not just sits higher. Rock Krawler has long been a leader in locking in Jeep suspension systems.

Why Rock Krawler?

Rock Krawler has earned its reputation as one of the most trusted names in Jeep and off-road suspension thanks to its trail-proven durability and American-made craftsmanship. Every kit is engineered for real-world performance, whether the goal is to improve on-road handling, gain serious articulation, or tackle the most technical trails.

Rock Krawler stands out through its innovative joint technology. Each control arm series is designed with specific joint types that align with different driving needs, from daily commuters to hardcore crawlers. Whether you’re building a mild weekend wheeler or a dedicated trail machine, choosing the right Rock Krawler control arms and understanding the joints they use can make or break your suspension setup.

Adventure Series: Simplicity Meets Comfort

For those who want a simple, reliable upgrade without losing comfort, Rock Krawler’s Adventure and Adventure X arms are fantastic starting points. The Adventure Series uses 100% service-free joints at both ends, delivering a quiet, maintenance-free ride that’s a clear step up from stock. These arms reduce factory bind by offering up to 70 degrees of misalignment and restore proper caster with a fixed length. Combined, these improvements deliver a much more stable driving experience and a smoother commute.

For more control, the Adventure X adds adjustability while keeping the same durable joints. This means you can fine-tune your suspension to fit your unique setup or terrain, dial in your ride height, or optimize articulation for trails without sacrificing that smooth, quiet ride.

X-Factor: Proven Performance with Rebuildable Strength

Rock Krawler’s X-Factor Series takes suspension enhancements a step further. These premium control arms are designed for the folks who want to take off-roading more seriously, offering full adjustability and long-term durability. These adjustable arms feature PRO Krawler Joints at the axle and Adventure Series joints at the frame mounts. This hybrid configuration balances trail-ready articulation with quiet, maintenance-free operation where it matters most.

The X-Factor line revolves around the PRO Krawler Joint, a fully rebuildable spherical joint built with exceptionally tight tolerances for consistent performance. Each joint features a heat-treated, zinc-plated chromoly housing for corrosion resistance and durability, while the hard-chrome-plated inner ball offers exceptional strength. The internal raceway provides outstanding wear resistance and vibration isolation, ensuring smooth operation even under extreme loads.

Combined with the frame-mounted Adventure joints, the system provides up to 95 degrees of total articulation, allowing precise tuning of caster and pinion angles to suit your build.

Ideal for frequent off-roaders and aggressive trail users, the X-Factor Series is a serious upgrade that enhances both geometry and articulation without compromising reliability or road manners.

X-Factor Pro: Maximum Flex, Maximum Strength

For those who push their Jeeps to the limit, the X-Factor Pro Series is the gold standard. Built from lightweight yet incredibly strong 7075 billet aluminum, these arms resist bending and fatigue even under the harshest conditions.

The Pro Series doubles down on adjustability, letting you fine-tune right on the vehicle. This means you can optimize your setup on the fly.

The hybrid joint setup, Pro Krawler Joints at the axle and Adventure Series joints at the frame, delivers up to 95 degrees of total misalignment with half the maintenance of comparable aluminum arm packages. The design also features user-friendly wrench flats for easy tightening of jam nuts, saving you time and frustration.

PB&J X-Factor Pro Elite: The Apex of Control Arm Engineering

When it comes to control arm systems, Rock Krawler’s PB&J X-Factor Pro Elite stands in a league of its own. At the heart of this setup are the strongest Krawler Joints ever produced, developed to tackle the harshest trails and the most aggressive articulation without breaking a sweat.

Crafted from beefy 2”x3” billet 7075 aluminum, the PB&J (Pure Beef & Jealousy) arms don’t just perform, they demand attention. The finish is clean, the design is aggressive, and the durability is second to none. It’s hardware with attitude, designed to back up its looks with elite, race-level performance.

This isn’t a system for weekend warriors or mall crawlers. The X-Factor Pro Elite is built for pros, competitors, and serious wheelers who know that compromise has no place under their rig. Whether you’re bombing through a rock garden or flexing on the podium, the PB&J delivers the articulation, strength, and precision that separates contenders from champions.

Build What You Drive

Rock Krawler doesn’t offer a one-size-fits-all solution, and that’s a good thing. Whether you’re trying to tame potholes on your daily commute or crawl over ledges in Moab, they’ve built a control arm to match. Choosing the right one starts with being honest about how you drive. If comfort and simplicity are your priorities, the Adventure Series arms make perfect sense. But if you’re chasing flex, strength, and trail domination, the Pro Elite arms are built with your name on them.

In the world of Jeep suspension, joints matter. And Rock Krawler makes sure that every one of them is built to meet your expectations—and then some.
