Enhanced Performance and Control

Upgrade your Jeep Gladiator JT (2020-Present) with our Cruise Series Rear Control Arm Set, designed to provide superior handling, durability, and axle alignment correction. This set includes both rear upper and rear lower control arms, working together to re-center the rear axle and correct pinion angles, ensuring a smoother, more controlled driving experience both on and off-road.

Key Features and Benefits

  • Heavy-Duty Steel Construction – Built from high-strength steel tubing for maximum durability and impact resistance.
  • Adjustable for 0 to 6 Inches of Lift – Allows for precise pinion angle correction and axle re-centering after lifting your Gladiator.
  • Tapered Polyurethane Bushings – Absorb vibration and enhance responsiveness, providing a smoother ride than stock rubber bushings.
  • Complete Rear Axle Alignment Solution – When paired with our Cruise Series Rear Track Bar (CRS-J-JT-RTB1), this set provides full control over rear suspension geometry, eliminating driveline vibrations and rear-end instability.

Two-Stage Powder Coating

Each control arm undergoes a two-stage powder coating process for maximum corrosion resistance and long-lasting durability. Zinc primer base coat ensures protection from rust and environmental wear. Top coat available in 10 color options, allowing for customization to match your vehicle’s build.

Proudly Made in the USA

Manufactured in Orem, UT, our Cruise Series Rear Control Arm Set is built to strict quality standards, ensuring reliability, strength, and superior performance.

Optional Hardware Upgrade

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.

First and foremost would like to say that Core4x4s customer service is top notch and they definitely stand behind their warranty on products! Highly recommend using them for any of your off road needs! It’s rare to find a company now a days that backs their products and they do! Had a few issues with mounts and control arms and they handled it without hesitation! Thank you!

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)

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.

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.

Beefy parts made and painted well, very fair pricing for what you get, and fantastic customer service to boot. Easily my favorite place to get suspension parts.

First off: Korby, the gentleman that helped me decide on which kit to go with is EASILY the nicest, and most patient person I’ve dealt with, when ordering parts for this build. Second: the quality of the product is INSANE! These parts are so nicely fabricated, then powder coated for extra longevity, and they even offer an aluminum upgrade in some cases (which I went with, to save weight). Having said all of this, the most impressive thing was the lead time. These parts are build to order, and I literally ordered my suspension one week ago, today! Yes, they built, powder coated, packaged, shipped my suspension components (RAM 1500 Track rear trailing arm full set in 7075 aluminum, and front upper control arms), AND they arrived, all within a week! Granted, that I’m only one state away, but WOW!!! One week?! Amazing! So, in sort: excellent products, which arrived excellently packaged (no damage, an boxes not over-stuffed with heavy suspension parts; three boxes total, as opposed to one super heavy one…my back thanks you), super quickly, and customer service that ANY business would be envious of….so, if you’re in the market, absolutely go with Core 4X4!
