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.

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

I have a 2016 RAM 1500 Crew Cab and I replaced the rear upper and lower control arms also the pan hard track bar and also the sway bar and links for the rear with all I had the articulating bushings. The vehicle now has no body role. They are absolutely incredible if you get the control arms you gotta get the CORE 4 x 4sway bar end links don’t don’t try and be cheap and get Moog or something else you got to get articulating bushings get the core 4 x 4 ones they are the best. My truck drives now through the canyons like a BMW. I have Fox high-performance shocks on there as well with all the CORE 4 x 4 suspension parts and they are amazing. Well worth the money I would highly recommend anybody thinking about CORE 4 x 4 go with CORE 4X4 and if you can go with their articulating bushings, they’re unbelievable drives better now than my Escalades. Well planted no body role and smooth on the Highway unbelievable the difference they all made!! THANKS AGAIN CORE 4x4!!!!

I’m extremely impressed with Core 4x4. The quality of their parts is outstanding — everything feels solid, well‑built, and engineered with real attention to detail. Shipping was fast and everything arrived perfectly packaged. Their customer service is just as good as their products: responsive, helpful, and genuinely committed to making sure you get exactly what you need. Overall, a top‑tier experience. I’ll definitely be buying from them again. Specially thank you Mr. Linscomb from Core 4x4. Arturo M.

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.

First off amazing products. I got a set of adjustable control arms for my XJ and it is so nice to be able to dial in caster and pinion angles. A quick call and I was able to purchase an adjustable track.

Good company, they offer well built parts and Great customer service. I had a couple of hang ups with my control arms that I purchased, they were very easy to work with and found the solution to make them work.

Core 4x4 excels with precision and service and keeps nothing else higher in mind. Everyone I've met at the company is very honest and down to earth, 10/10 would recommend.

Purchased a set of Trailing arms for my Ram 1500, quality is first class. I bought the ones with the Jonny Joints for more articulation and it appears from the construction I should get a lifetime of use, Zerk fittings are an added plus. Would defiantly recommend, and the the service team answered all of my questions.

To start off if you're looking to upgrade your control arms definitely hit this company up. Great product, easy install of the product, with three different tiers everything is priced pretty good, I'm a sticker guy and they sent a sticker for each arm each track bar and also three extra ones so the extra are on the Jeep the advertise them for sure. If you're reading this review I highly recommend you to check their website out.
