Rock Krawler 07-18 Jeep Wrangler JKU 4DR 3.5in Ultimate Adventure System

This Rock Krawler 3.5-inch Ultimate Adventure System for your 2007-2018 Jeep Wrangler JKU 4-door gives you a complete package to significantly improve your off-road capability. You're getting a full suite of components designed to work together, including front and rear adjustable control arms, front and rear track bars, front and rear sway bar disconnects, and a rear brake line relocation bracket. This system is built to handle the demands of serious trail use, offering improved articulation and ground clearance.

Rock Krawler is known for building tough suspension parts, and this system is no exception. The adjustable control arms are a key feature, allowing you to dial in your caster and pinion angles precisely after lifting your Jeep. This helps restore proper suspension geometry, which is crucial for good on-road manners and predictable handling off-road. The included track bars keep your axles centered under the Jeep, preventing steering wander and ensuring stability, especially with larger tires. The sway bar disconnects make it easy to gain maximum articulation when you're crawling over obstacles, and they can be reconnected for safer highway driving. The rear brake line bracket ensures your brake lines have enough slack and aren't stressed when the suspension is at full droop.

When you're planning a significant suspension upgrade like this, it's important to consider what else might be needed. Depending on your tire size and intended use, you might also need longer shocks, a driveshaft upgrade, or potentially a steering stabilizer. Rock Krawler designs these systems with a focus on durability and performance, so you can be confident that the core components are well-built for adventure. Always refer to the manufacturer's installation instructions for the most accurate guidance on fitting this system to your JKU.
