Transform Your ZJ’s Suspension for Maximum Off-Road Performance
The CORE 4X4 Crawl Series Long Arm Upgrade Kit is a complete suspension overhaul for the 1993-1998 Jeep Grand Cherokee ZJ, delivering unparalleled ride quality, strength, and off-road capability. By eliminating the factory short-arm suspension and replacing it with precision-engineered long arms and high-strength mounting brackets, this kit dramatically improves axle stability, suspension cycling, traction, and handling. With extended suspension geometry, this kit allows your axles to cycle on a longer arc, resulting in a smoother ride, improved articulation, and optimized stance.
Whether you’re daily driving, rock crawling, or desert racing, this bolt-on system provides the durability and control needed to tackle any terrain.
Key Features and Benefits
- Optimized Suspension Travel Geometry – Extends control arm mounting points, allowing axles to move on a longer suspension arc for a smoother ride and better traction. Eliminates axle bind and short-arm limitations, allowing for increased suspension articulation. Reduces body roll and improves high-speed stability while maintaining low-speed crawling capability.
- Heavy-Duty DOM Tubing Construction – 1.75” OD DOM tubing for lower arms and 1.5” OD DOM tubing for upper arms, providing extreme durability and impact resistance. Double-threaded left- and right-hand adjusters allow for on-vehicle fine-tuning without removal. (Front upper control arms are fixed due to the U-bracket design.)
- Precision-Cut and Bent 1/4” Steel Brackets – Replaces factory short-arm mounting brackets with reinforced, heavy-duty weld-on brackets designed for maximum strength and long-term performance. Integrated body mount relocation on rear brackets, ensuring proper clearance for full suspension travel.
- Full Suspension Overhaul for Maximum Performance – Eliminates factory suspension limitations, providing significantly better ride quality, handling, and stance. Improves axle centering, caster, and pinion angles, ensuring proper drivetrain geometry and reducing stress on suspension components. Designed for heavy off-road use, daily driving, and load-bearing applications, making it the ultimate upgrade for any ZJ build.
Durable Powder Coating for Long-Lasting Protection
To ensure maximum durability and corrosion resistance, each component undergoes a two-stage powder coating process. The zinc primer base coat provides superior protection against rust, while the durable top coat—available in 10 color options—adds an extra layer of resilience and customization to match your Jeep’s build. Brackets are left raw to ensure proper welding and post-installation finishing.
