Optimized Performance for Stability and Control

Eliminate axle misalignment, vibration, and rear-end instability with our Cruise Series Rear Upper Control Arms, designed specifically for Jeep Grand Cherokee WK models from 2005-2010. These control arms provide critical pinion angle correction, ensuring driveline stability, improved handling, and long-term durability—whether you're tackling tough trails or cruising on the highway.

Key Features and Benefits

  • Heavy-Duty Steel Construction – Built to withstand harsh terrain and heavy loads while ensuring maximum durability.
  • Adjustable for Perfect Pinion Angle – Maintains proper alignment and driveline geometry for lifts from 0 to 6 inches.
  • Tapered Polyurethane Bushings – Reduces noise, vibration, and harshness (NVH) while improving ride comfort and flexibility.
  • Greaseable and Rebuildable Joints – Designed for easy maintenance and long-term performance, keeping your suspension system in peak condition.
  • Recommended Pairing – Combine with Cruise Series Rear Lower Control Arms (CRS-J-WK-RL2) for complete rear-end alignment and axle recentering.

Precision Alignment and Drivability Enhancement

When lifting your Jeep Grand Cherokee WK, the rear pinion angle shifts, leading to driveline vibrations, premature wear, and unpredictable handling. These adjustable upper control arms allow precise pinion angle correction, ensuring smooth power delivery and reduced drivetrain stress. By pairing them with our Rear Lower Control Arms, you get full axle recentering and alignment correction, preventing excessive tire wear and instability.

Two-Stage Powder Coating for Maximum Durability

All control arms go through a two-stage powder coating process to ensure corrosion resistance and long-lasting durability: Zinc primer base coat – Provides enhanced rust protection. Durable top coat – Available in 10 color options, allowing you to customize your suspension’s look.

Made in the USA

Proudly manufactured in Orem, UT, using high-quality, locally sourced materials to guarantee precision, durability, and superior performance.

Optional Hardware Upgrade

Designed for easy installation using factory hardware. If you’re dealing with rusted or seized bolts, we offer optional Grade 8 hardware kits, available separately, to ensure a smooth installation process.

Upgrade your Jeep today for a smoother, more controlled ride—on and off the road!

Awesome product and service! I even got some of their swag because it looked pretty darn good. I will definitely be going back and would suggest this business to others looking for quality control arms. Buy local!

Ordered a set of Core 4x4 control arms for my 2006 Jeep TJ. These are some heavy duty quality control arms. Can't wait to get them installed. Great customer service too!

The parts are a massive improvement over factory. I accidentally ordered the wrong endlinks and they helped me figure out the correct size and sent me new ones. Definitely an awesome store

Small business, family owned, made in the USA, lifetime warranty. Purchased Tier 3 control arms and rear track bar for a 2006 Jeep LJ. Simple website and easy to contact over phone and email. I had some technical questions and they were happy to answer them. They allow local pickup and were built to order same week. The order was wrapped and ready when I walked in and even gave a tour of the shop. They abrasive blast all raw materials to achieve a better surface profile for powdercoat to adhere and create a smooth, durable finish. I also noticed several CNC machines and a robotic welder they use for all their parts. A small outfit with a robotic welder? Their concern for quality is obvious and it shows in the parts they make. Very impressed. Happy to do business with these guys.

Great company, who worked with me on shipping parts to arrive in time for a show. When I explained my concern they went above and beyond to make it happen. Quality of the parts is top notch.
