Rock Krawler JL45TX2-4XE 4.5in T-Rex Hybrid Suspension Lift System Front & Rear

The Rock Krawler JL45TX2-4XE is a 4.5-inch T-Rex Hybrid Suspension System engineered specifically for the 2-door Jeep Wrangler JL equipped with the 4XE plug-in hybrid powertrain. This complete front and rear lift kit delivers an exceptional balance of on-road ride quality and serious off-road performance—without requiring any modification to the 4XE's high-voltage trunk lines or fuel system.

The T-Rex Hybrid design was developed to address the unique packaging challenges of the 4XE platform. Because the 4XE's cooling and high-voltage trunk lines run directly through the area where full long-arm front mounts would otherwise go, Rock Krawler engineered a purpose-built solution: a full high-clearance mid-arm front setup paired with an ultra high-clearance 3-link rear conversion. This combination maximizes geometry improvement while keeping the factory hybrid systems completely intact.

Key Features:

• 4.5-inch lift height with complete front and rear suspension system
• High-clearance X-Factor mid-arm front suspension for improved geometry and articulation
• Ultra high-clearance independent 3-link rear conversion with X2 rear suspension geometry
• High-clearance rear axle mounts deliver 4.5 inches of additional ground clearance under the rear axle vs. stock
• Rear upper shock relocation brackets preserve full shock travel—no travel is sacrificed
• Eliminates the natural binding and axle jacking inherent in the stock parallel 4-link/5-link rear suspension
• Raised rear roll center reduces side-to-side axle shifting during off-road use
• Triple-rate coil springs provide on-road comfort that rivals or exceeds OEM springs
• Adjustable control arms allow precision tuning of caster and pinion angles front and rear
• Correction pads included to reduce factory spring bow
• Front and rear track bar geometry corrections to properly center both axles
• Designed to preserve all factory 4XE hybrid systems—no high-voltage line modifications required
• Upgradeable: compatible with future full long-arm conversion if fuel/hybrid system modifications are later performed

Rock Krawler's T-Rex Hybrid System is purpose-built for 4XE owners who demand the best off-road geometry available without compromise to their hybrid drivetrain. The complete front and rear system transforms trail capability while maintaining a refined, comfortable daily driving experience.
