  • Construction: Built from heavy-duty steel tubing with tapered polyurethane bushings for enhanced durability, vibration absorption, and long-lasting articulation.

  • Two-Stage Powder Coating: Zinc primer base and top coat available in 10 vibrant colors protect against corrosion and allow for personalized styling of your rig.

Optimized Rear Suspension Control

Upgrade your Jeep Wrangler TJ or LJ (1997-2006) with the Cruise Series Rear Upper Control Arms, designed to correct pinion angle, recenter the rear axle, and eliminate driveline vibrations. These control arms provide greater strength and adjustability over stock components, making them a must-have upgrade for lifted Jeeps looking to improve handling and drivetrain longevity.

Key Features and Benefits

  • Pinion Angle Correction – Properly adjusts pinion angle to eliminate driveline vibrations and reduce wear on drivetrain components.
  • Rear Axle Recentering – Ensures accurate axle alignment to maintain stability and handling after lifting your Jeep.
  • Heavy-Duty Construction – Built from heavy-duty steel tubing for unmatched durability in on- and off-road conditions.
  • Polyurethane Bushings – Provides superior responsiveness, vibration absorption, and longevity over standard rubber bushings.
  • Recommended Pairing – For complete rear-end suspension alignment and axle centering, pair with our Cruise Series Rear Lower Control Arms (CRS-J-TJLJ-RL2).

Precision Adjustability

Our fully adjustable Rear Upper Control Arms are engineered to fine-tune pinion angle and re-align the rear axle. With a range supporting 0 to 6 inches of lift, they provide crucial adjustments to optimize handling and drivetrain function. If your lift exceeds 6 inches, contact us for additional options.

Two-Stage Powder Coating

For maximum durability and corrosion resistance, all control arms undergo a two-stage powder coating process: Zinc primer base coat – Provides rust protection. Durable top coat – Available in 10 customizable colors for a long-lasting, stylish finish.

Made in the USA

Proudly manufactured in Orem, UT, our Cruise Series components support American craftsmanship and are built to the highest performance and durability standards.

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!

I wanted to take a moment and give these guys a shout out, I’ve currently got, for my xj, their adjustable control arms, tier 4 adjustable track bar and adjustable leaf spring shackles. You can always count on a fair price, high quality products, and quick delivery. Keep up the great work guys, will definitely continue to shop with you

Ran into an issue with a part that I ordered. Got ahold of them explained to them the issue I was having and they jumped in and got the issue fixed. Hands down the best customer service I have ever dealt with. The parts are hands down amazing. Highly recommend.

Installed rear and upper control arms and track bar on my 3rd Gen 4RUNNER to align rear axle and restore factory wheel base after 3.5" lift. Car drives better than New! Improved handling cornering and overall driving. Very solid and high quality made product. Support is outstanding. Shipping extremely fast. Thank you so much. I wish you will have something new for my car.

Ive had the front adjustable control arm kit in bright green for my 1996 ZJ. Ive had the kit for about a year now and i have to say, im extremely impressed, over 1000 miles off-road and roughly 20,000 miles on the highway. These control arm kits for any vehicle built by core 4x4 are well worth the money, just be aware thereight be some minor scatches or chips from shipping ( but who should care about that if you're beating the crap out of em' they way they were built and designed for)

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!

I have nothing but great things to say about this company and their customer service. If you like American made products backed by warranty and amazing customer support, this is the company for you. I have a Lexus GX470 and love their rear control arms.
