Performance and Comfort

Upgrade your Jeep Wrangler TJ or LJ with the Cruise Series Rear Control Arm Set, designed to enhance both off-road capability and on-road comfort. This set includes adjustable upper and lower rear control arms, significantly improving axle alignment, suspension articulation, and overall drivability.

Built to withstand rugged trails and highway conditions alike, this upgrade ensures long-term durability and superior performance over factory components.

Key Features and Benefits

  • Enhanced Strength and Durability – Built from heavy-duty steel tubing, these control arms provide superior strength over factory components.
  • Precision Adjustability – Fully adjustable to accommodate 0 to 6 inches of lift, ensuring proper axle centering and pinion angle correction.
  • Optimized Drivability – Corrects rear axle misalignment and improves handling, reducing tire wear and suspension stress.
  • Recommended Pairing – For complete rear-end alignment and full pinion angle control, pair with our Cruise Series Rear Track Bar (CRS-J-TJLJ-RTB1).

Full Rear Suspension Control

When lifting your Jeep, improper pinion angles and axle misalignment can lead to driveline vibrations and handling instability. This rear control arm set allows for precise axle centering and pinion angle adjustments, eliminating these common suspension issues.

When paired with our Rear Track Bar, this combination ensures optimal handling and maximum rear-end stability in all driving conditions.

Two-Stage Powder Coating

Each control arm is coated with a two-stage powder coating process for maximum durability: Zinc primer base coat provides superior corrosion resistance. Top coat available in 10 color options, allowing you to personalize the look of your suspension components.

Made in the USA

All Cruise Series components are proudly manufactured in Orem, UT, ensuring the highest quality craftsmanship while supporting American manufacturing.

Optional Hardware Upgrade

  • Our Rear Control Arm Set is designed for easy installation using factory hardware.
  • For those dealing with rusted or seized bolts, we offer optional Grade 8 hardware kits, available separately, to make the installation process seamless.

Whether you’re tackling tough trails or cruising on the highway, these control arms will correct pinion angle, recenter the rear axle, and provide enhanced drivability.

Pair with our Cruise Series Rear Track Bar for complete rear suspension control and enjoy a smoother, more stable ride.

Very beefy items for a very reasonable price.  Personally have CORE rear track bar and all upper control arms for my 04 Jeep TJ.  Had a slight issue with control arm length and they went above and beyond to swap jam nuts to get me where I needed to be.  Really have to appreciate a company like this.

Had a worn out set of rear upper control arms on my TJ. These were old rubicon express long arms. can’t buy replacements and no one makes a direct fit replacement. Talked with Korby at core off road sent some measurements and photos and a week later new arms showed up. Packaging was perfect fit was perfect. Would highly recommend giving these guys a call.

2001 Wrangler TJ- i have purchased all front/rear upper/lower control arms. Front track bar and rear track bar. Quality is excellent and extremely durable you can tell its built to last. Bent a bolt on the front track bar and called and spoke with Spence. He immediately sent me out new hardware plus some! Product is amazing but what really separates companies apart is their service and these guys are second to none. Thank you all!

Absolutely incredible family owned business. I asked to pick up my order since I’m local and they came in on a weekend to accommodate. Had to make some adjustments to parts and took the time to make sure it was perfect. Parts are incredible quality. If you have a Jeep, do not hesitate to support this local business.

Amazing service. Bought a track bar through Americantrucks.com and they sent it with the wrong size bushing sleeve. Korby at Core 4x4 was quick to get me the correct size and very responsive. Will definitely be using more of their stuff.

Excellent quality product and service. My l lower control arms broke and within the same day core 4x4 hooked me up with tier 2 arms and with the color I wanted. My Jeep rides better and has been solid for several months so far. 10/10 would recommend their products to anyone.
