Unmatched Strength and Flexibility
Upgrade your Jeep Grand Cherokee WJ (1999-2004) with the Crawl Series Front Lower Control Arms, delivering extreme durability, superior articulation, and precise alignment correction. Designed for off-road enthusiasts and daily drivers alike, these heavy-duty control arms provide exceptional strength and flexibility while maintaining outstanding on-road performance.
Key Features and Benefits
- Heavy-Duty DOM Tubing for Maximum Strength – Built from 1.75” OD 5/16” wall DOM Tubing, these control arms far surpass factory components in durability, ensuring your suspension can handle intense off-road conditions and everyday driving with ease.
- Johnny Joints for Superior Articulation – Equipped with RockJock Johnny Joints at both ends, these arms provide unmatched flexibility and movement, allowing your suspension to perform optimally even under extreme articulation. This means smoother, more controlled handling on rough trails without binding.
- Adjustability for Lifts from 0 to 6 Inches – Designed to work with stock height and lifted vehicles, these control arms allow for precise axle centering and alignment correction, improving handling and reducing premature wear on suspension components.
- Pair with Front Upper Control Arms for a Complete Solution – For maximum performance and alignment control, we recommend pairing these with the Crawl Series Front Upper Control Arms (CRL-J-WJ-FU2) to fully optimize front-end suspension geometry for superior handling on and off the road.
Two-Stage Powder Coating
Each control arm undergoes a two-stage powder coating process for extreme durability and corrosion resistance.
- Zinc primer base coat provides a strong barrier against rust.
- Durable top coat, available in 10 colors, ensures a custom look and lasting protection.
Proudly Made in the USA
Manufactured in Orem, UT, our Crawl Series Control Arms represent the highest standards of American craftsmanship and engineering. We oversee the entire production process to ensure superior quality and long-lasting performance.
