Unmatched Off-Road Performance On-Road Comfort
Upgrade your Jeep Grand Cherokee ZJ with the Crawl Series Front Long Arm Upgrade Kit, engineered for superior suspension articulation, axle stability, and overall ride quality. Whether you're tackling rocky trails, high-speed desert runs, or daily driving, this long arm kit is designed to handle it all. With extended control arms, this kit optimizes suspension geometry for a smoother ride and better traction, even in extreme off-road conditions.
Key Features and Benefits
- Heavy-Duty Construction – Built from 5/16” wall DOM tubing, these long arms provide superior durability and articulation over factory and short-arm setups.
- Optimized Suspension Geometry – The longer control arms cycle on a longer arc, improving axle movement, reducing stress on suspension components, and enhancing ride quality.
- Precision-Engineered Brackets – 1/4” laser-cut and precision-bent steel brackets ensure a perfect fit and unmatched strength.
- Increased Ground Clearance Travel – Unique upper control arm bends allow for maximum up-and-down travel without body modifications.
- Full Bolt-On Installation – No welding required—bolt-on design makes installation straightforward with included hardware.
Two-Stage Powder Coating for Maximum Protection
Every component in this kit undergoes a two-stage powder coating process for enhanced durability and corrosion resistance. Zinc primer base coat prevents rust and protects against harsh environmental conditions. Durable top coat available in 10 custom colors for added protection and personalization. Custom colors available upon request.
Proudly Made in the USA
Manufactured in Orem, UT, the Crawl Series Front Long Arm Upgrade Kit is built to the highest standards of American craftsmanship. By choosing CORE 4X4, you’re investing in high-quality, American-made products designed to withstand the most demanding conditions.
Optional Hardware Upgrade
Designed for easy installation using factory hardware. For those dealing with rusted or stubborn bolts, optional Grade 8 hardware kits are available separately for a hassle-free setup.
Vehicle Fitment: Jeep Grand Cherokee ZJ 93-98 – Upgrades your front suspension with a true 4-link long-arm design, delivering unmatched articulation, down travel, and ride quality for both on- and off-road performance.
CORE Advantage: Unlike radius arm designs that limit articulation and create bind, this true 4-link system allows each wheel to move independently, increasing suspension travel and maintaining stability across uneven terrain.
Adjustability: Extended arm geometry corrects axle positioning, optimizes caster and pinion angle, and reduces driveline vibrations—resulting in smoother handling and enhanced suspension efficiency.
Construction: Built from heavy-duty 5/16” wall DOM tubing, reinforced with 1/4” laser-cut plate steel brackets for maximum strength, ensuring durability in extreme conditions.
Two-Stage Powder Coating: Zinc primer base and top coat available in 10 vibrant colors protect against corrosion and allow for personalized styling of your rig.
Warranty and Origin: Proudly manufactured in the United States, our product includes a lifetime warranty on all non-wear items, providing you with confidence and peace of mind in your purchase.
