Whether you're tackling off-road trails or cruising the highway, these control arms offer a significant upgrade over factory components, ensuring superior axle alignment and stability.
What’s Included in the Kit?
- Camp Series Rear Upper Control Arms (CMP-J-JL-RU2)
Key Features and Benefits
- Engineered for Strength – Constructed from 1.5” OD DOM Tubing with 5/16” wall thickness, these control arms offer exceptional durability compared to factory components.
- Optimized Suspension Geometry – Adjustable design allows for precise alignment correction and rear axle re-centering, essential after installing a lift.
- Premium Joint Technology – Features a Johnny Joint at the adjusting end for superior articulation and a tapered polyurethane bushing at the axle end to reduce vibration and enhance longevity.
- Recommended Pairing – For optimal rear suspension performance, pair these control arms with our Camp Series Rear Lower Control Arms (CMP-J-JL-RL2) for complete rear-end stability and alignment correction.
Precision Adjustability for Lifted Vehicles
Lifting your Jeep Wrangler JL alters the factory suspension geometry, which can lead to misalignment, premature tire wear, and reduced stability.
Our adjustable rear upper control arms allow you to fine-tune your pinion angle and reposition your rear axle to maintain optimal handling and drivability.
- Designed to accommodate lifts from 0 to 6 inches for maximum suspension flexibility.
- For lifts beyond 6 inches, contact us for custom solutions.
Two-Stage Powder Coating for Maximum Durability
Each control arm undergoes a two-stage powder coating process for superior protection against rust and corrosion. Zinc primer base coat ensures a strong barrier against environmental damage. Durable top coat, available in 10 color options, allows for customization while maintaining long-term durability.
