Description
Upgrade your Jeep Wrangler 4xe Hybrid JL or JLU Unlimited with the RockJock Pro Edition Johnny Joint Suspension System, a premium suspension lift kit engineered specifically for hybrid Wrangler platforms. Designed to deliver approximately 3.5 inches of lift, this Jeep 4xe suspension upgrade provides clearance for up to 37-inch tires, with larger tire fitment requiring aftermarket fenders and minor trimming.
Built for serious off-road enthusiasts, the Pro Edition Johnny Joint Suspension System represents the highest level of RockJock engineering, combining superior strength, precise fitment, refined finish, and proven suspension geometry. Every component is designed for long-term durability and dependable performance in demanding conditions while maintaining compatibility with the Jeep 4xe hybrid system.
This Jeep Wrangler 4xe lift kit is engineered to deliver a strong balance between on-road comfort and off-road capability. It maintains smooth, controlled daily drivability while significantly improving suspension articulation, stability, and traction on technical terrain, making it ideal for overlanding, trail driving, and moderate off-road use.
A key feature of this system is the included front control arm geometry correction brackets, which restore proper suspension geometry after lifting. This helps return the vehicle to near-stock drivability, improving steering feel, handling stability, and overall on-road comfort even with increased ride height and larger tires.
For enthusiasts planning more advanced off-road builds, RockJock offers a full range of compatible upgrade components that can be added over time. This allows the Pro Edition system to evolve into a more capable rock crawling or high-performance suspension setup as driving demands increase.

Kit Features:
- RockJock Spec. Dual-Rate Springs – Feature a soft initial rate that absorbs small bumps and trail chop, to deliver a smooth, comfortable ride, while a firmer secondary rate helps soak up larger impacts and reduce bottoming. A key differentiator of RockJock spec. dual-rate springs is the positioning of the crossover point between the initial and secondary spring rates so that a portion of the softer initial rate is available and active at ride height before crossing over to the firmer secondary rate deeper into the travel.
- Bump Stop Spacers – Proper bump stop extensions are a must and our heavy duty kits stand up to hard use while keeping the tires off of the shiny new JL fenders!
- Johnny Joint Control Arms – Heavy duty adjustable upper control arms feature RockJock Johnny Joints, the original and most durable high-articulation urethane suspension joint on the market. Johnny Joints feature a smooth steel ball that pivots inside a proprietary urethane shell to provide over 30 degrees (per joint) of quiet, shock dampening articulation – without the excessive deflection found in soft rubber-based flex joints. Johnny Joints are so trusted, that they are used by multiple commercial suspension companies, for both street and off-road suspension systems.
- Johnny Joint Trac Bar – Forged chromoly, organically shaped front trac bar combines a precise fit with incredible strength and rigidity that is only available via forging. The adjustability feature allows you to perfectly center front axle under the vehicle. High-articulation Johnny Joint ends provide maximum durability and suspension flex.
