Enhance Your Jeep’s Suspension for Maximum Comfort and Control
Upgrade your Jeep Wrangler JK (2007-2018) with the Camp Series Rear Upper Control Arms, engineered to improve on-road comfort, off-road articulation, and suspension durability.
These adjustable control arms provide better axle alignment, improved handling, and reduced drivetrain stress, making them a crucial upgrade for lifted Jeeps.
Key Features and Benefits
- High-Strength DOM Tubing – Constructed from 1.5” OD DOM tubing with a 5/16” wall thickness, these control arms are significantly stronger than factory components, ensuring increased durability and long-term performance.
- Precise Axle Alignment – Adjustable design corrects rear axle positioning, reducing drivetrain strain and ensuring proper suspension geometry after lifting your Jeep.
- Johnny Joint for Maximum Flexibility – The adjustable end features a RockJock Johnny Joint, providing exceptional articulation, reduced wear, and smoother off-road maneuverability.
- Tapered Polyurethane Bushing – The axle end is equipped with a durable polyurethane bushing, absorbing vibrations and enhancing ride quality.
- Optimized Suspension Geometry – Adjusts to accommodate lifts from 0 to 6 inches, preventing issues like incorrect pinion angle and excessive driveshaft wear.
- Recommended Pairing – For optimal performance, we recommend pairing these arms with our Camp Series Rear Lower Control Arms (CMP-J-JK-RL2) to ensure proper rear axle alignment and improved stability.
Why Proper Rear Axle Alignment Matters
Lifting your Jeep Wrangler JK can throw off suspension geometry, leading to poor alignment, excessive driveshaft angles, and axle misalignment.
Without adjustable upper control arms, your pinion angle may become incorrect, causing:
- Driveline vibrations
- Excessive wear on U-joints
- A rough ride
The Camp Series Rear Upper Control Arms allow you to fine-tune your axle position, ensuring your Jeep drives smoothly and efficiently while maximizing off-road articulation and traction.
Two-Stage Powder Coating for Maximum Durability
Every Camp Series Rear Upper Control Arm undergoes a rigorous two-stage powder coating process for superior corrosion resistance and longevity: Zinc primer base coat – Provides a barrier against rust, road salt, and harsh environmental elements. Durable top coat in 10 color options – Adds long-lasting protection and allows you to customize your Jeep’s suspension to match your build.
Proudly Made in the USA
Manufactured in our Orem, UT facility, our Camp Series Rear Upper Control Arms are crafted with American-made quality and precision.
We use locally sourced materials and oversee the entire production process to ensure every part meets our high standards for durability and performance.
Optional Hardware Upgrade
Designed for easy installation using factory hardware, but if your Jeep has rusted or worn-out bolts, we offer optional Grade 8 hardware kits, available separately, to ensure a smooth installation.
- Correct rear axle alignment
- Improve ride quality
- Enhance off-road performance
With heavy-duty construction, full adjustability, and premium joint technology, these control arms ensure a smoother ride, better suspension articulation, and maximum durability.
