Total Control Over Caster and Axle Alignment

The Jeep Gladiator JT’s factory suspension suffers from insufficient caster, leading to wandering, instability, and rut tracking—especially after a lift. CORE 4X4’s Cruise Series Front Control Arm Set completely eliminates these issues, allowing for precise caster correction and axle centering. With both front upper and lower control arms, this set gives you full control over your alignment, improving steering response, high-speed stability, and off-road capability.

Key Features and Benefits

  • Corrects Caster Deficiencies – Eliminates wandering, instability, and rut-following by restoring proper caster angles.
  • Re-Centers the Front Axle – Ensures correct wheel placement in the wheel well, improving alignment and tire wear.
  • Adjustable for Lifts (0-6”) – Optimizes suspension geometry for stock height up to 6-inch lift setups.
  • Tapered Polyurethane Bushings – Reduces noise, vibrations, and harshness (NVH) for smoother suspension movement.
  • Heavy-Duty Steel Construction – Built from high-strength steel tubing for superior durability.
  • Recommended Pairing for Maximum Stability – Combine with our Cruise Series Front Track Bar (CRS-J-JT-FTB1) to further reduce death wobble and improve steering precision.

Two-Stage Powder Coating for Maximum Protection

Every control arm undergoes a two-stage powder coating process to ensure long-term durability and corrosion resistance: Zinc Primer Base Coat – Forms a rust-resistant barrier for extreme conditions. Customizable Top Coat – Available in 10 colors to match your Gladiator’s build while adding extra protection.

Made in the USA

Proudly designed, tested, and manufactured in Orem, UT, our Cruise Series Control Arms meet the highest American craftsmanship and quality control standards.

Optional Hardware Upgrade

  • Our Front Control Arm Set installs using factory hardware.
  • However, if your vehicle has rusted, seized, or worn-out bolts, we offer optional Grade 8 hardware kits for a smoother and more secure installation.

For even more front-end control, pair these with our Cruise Series Front Track Bar (CRS-J-JT-FTB1) to further reduce death wobble and optimize steering response.

Upgrade today and take full control of your Jeep’s suspension performance!

First of I just want to say Great customer service korby Has helped me from the start and has not let me down! Reached out to him again today and he was able to warranty some parts out for me. As far as the quality of the parts.. excellent! The build quality is great. I can definitely tell a Difference from the cheap oem rear control arms to these and the pan hard bar. Color, From what I can tell it’s super durable been through a few mud holes on top of the daily road grime and after a quick wipe they still pop! Overall I recommend. Customer service is everything for me and it’s definitely there at Core 4x4.

The customer service is first class. I had an issue with a track bar I installed on my F350. I don’t have any other Core 4x4 parts yet, but with the way I was treated, I know their parts are well done, because they went above and beyond to make sure I was made whole. They wouldn’t be in business if they had to take care of a lot of people like they took care of me. Will definitely be back when it’s time to build the Jeep!

I contacted these guys on a Saturday through email and needed some control arms by the following weekend, Spence got back with me and told me he would make sure the order got shipped out on Monday, they got busy and wasn’t able to ship the package out so he got back with me that evening and upgraded my shipping for free and shipped out the next day, only because he told me he’d make sure I’d have them by the weekend! This company sticks to their word! The customer service from these guys are unmatched and they will have another lifetime customer here!

Korby was extremely helpful in helping me find the right part for my truck. He was kind, knowledgeable, and patient while I asked a million questions. He also went out of his way to find the right shipping option for me since it’s tricky where I live. I’m looking forward to getting the parts so I can fix my truck and go adventuring again soon!

The folks at Core 4X4 are always wonderful to deal with. They explain your options and never pressure or rush things. The quality of the Core Control Arms is top shelf, especially if your goal is to stop wheel hop. I recommend Core 4x4 without reservation ! ! !

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.

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.
