Upgrade Your Jeep Grand Cherokee WJ’s Suspension
Enhance your Jeep Grand Cherokee WJ’s performance with the Camp Series Front Upper Control Arms. Designed to improve handling, alignment, and stability, these control arms are essential for maintaining optimal suspension geometry and drivability on lifted vehicles. Built for strength, flexibility, and durability, they are a substantial upgrade over factory components, ensuring exceptional performance on and off the road.
Key Features and Benefits
- Engineered for strength and durability – Constructed from 1.5" OD DOM Tubing with a .313" wall thickness, these control arms are built to handle extreme conditions while maintaining on-road comfort.
- Premium joint technology – Features a Johnny Joint at the adjustable end for superior articulation and a U-bracket at the axle end, ensuring a secure and reliable connection.
- Adjustable for lifted vehicles – Fully adjustable to accommodate lifts from 0 to 6 inches, allowing precise alignment correction, axle positioning, and improved handling.
- Recommended pairing – Works best when paired with our Camp Series Front Lower Control Arms for a complete front-end solution, especially for lifts over 3 inches to maintain proper geometry and reduce driveline vibrations.
