Why Builders Choose CORE 4X4

Warranty facts, not marketing language.

vs. MetalCloak

Their “lifetime” language refers to their service model. Actual parts warranty: 1 year. Ours: lifetime.

vs. Teraflex

Skip a maintenance interval? Their warranty voids. Ours doesn’t.

vs. Clayton Off Road

Clayton warrants their Johnny Joints for 90 days. We cover ours for life.

Correct Your Caster and Take Full Control of Your Suspension

Upgrade your Jeep Gladiator JT (2020-Present) with the Camp Series Front Control Arms Set, designed to correct the factory caster deficiency while improving axle positioning, handling, and overall suspension performance. This set includes Front Upper Control Arms and Front Lower Control Arms, offering a complete solution to regain stability, steering precision, and ride quality.

What’s Included in the Kit?

  • Camp Series Front Upper Control Arms (CMP-J-JT-FU2)
  • Camp Series Front Lower Control Arms (CMP-J-JT-FL2)

Key Features and Benefits

  • Corrects Caster for Improved Driveability – The Gladiator’s factory suspension lacks sufficient caster, leading to unstable steering and wandering at higher speeds. These control arms restore proper caster angles, improving handling, cornering, and high-speed stability.
  • Superior Strength and Durability – Constructed from 1.75" OD DOM Tubing for the lowers and 1.5" OD DOM Tubing for the uppers, both with a .313" wall thickness, these arms are built to withstand aggressive off-road conditions while maintaining on-road comfort.
  • Johnny Joint and Polyurethane Bushing Combination – Features Johnny Joints at the adjustable ends for maximum articulation and tapered polyurethane bushings at the axle ends for vibration dampening and long-term durability.
  • Adjustable for Lifted Vehicles – Accommodates suspension lifts from 0 to 6 inches, allowing for precise axle re-centering and alignment correction. For lifts over 6 inches, contact us for additional options.
  • Recommended Pairing – For total front-end stability and precise axle alignment, we recommend pairing these control arms with the Camp Series Front Track Bar (CMP-J-JT-FTB1) for the ultimate Gladiator suspension upgrade.

Optimized Suspension Performance

The factory Gladiator suspension geometry struggles with caster misalignment, which can cause vague steering and reduced handling precision. The Camp Series Front Control Arms correct these issues, keeping your axle properly positioned and suspension dialed in, whether you're on the road or the trail.

Two-Stage Powder Coating for Maximum Durability

Each control arm undergoes a two-stage powder coating process for superior protection against rust and corrosion. A zinc primer base coat ensures long-term resistance, while the top coat (available in 10 colors) lets you customize your Jeep’s look.

Proudly Made in the USA

All Camp Series components are designed and manufactured in Orem, UT. By keeping production in-house, we ensure strict quality control while supporting American manufacturing.

Straightforward Installation

The Camp Series Front Control Arms Set is designed for easy bolt-on installation using factory hardware. If your stock bolts are rusted or worn, we offer optional Grade 8 hardware kits for a hassle-free installation.

In Conclusion

Upgrading to the Camp Series Front Control Arms Set gives you full control over your Jeep Gladiator’s suspension, correcting factory caster issues, improving stability, and optimizing axle alignment. Pair it with the Camp Series Front Track Bar (CMP-J-JT-FTB1) for the ultimate front-end suspension solution. Upgrade today and experience the difference in driveability, performance, and durability.

Select your lift size in Step 1 — the kit ships with the correct geometry for that height. If you’re running a non-standard setup, call us before ordering and we’ll confirm compatibility.

Death wobble is a geometry problem, not just worn parts. Cruise Series corrects caster angle and eliminates the flex points that let shimmy start. Replacing one part at a time delays the fix — this replaces the geometry.

Yes, if you’ve done a lift kit before. Full-day project. Watch the complete JT install walkthrough on our YouTube channel — most owners wrap it in a day. Any off-road shop can run it if you’d rather have it done.

Any non-wear component fails — we replace it. No mileage cap. No maintenance intervals to track. No fine print about voiding if you miss a service. Lifetime means lifetime.

Teraflex’s lifetime warranty voids if you miss a maintenance interval. MetalCloak’s actual parts warranty is 12 months — their “lifetime” language refers to their service program. No conditions here.

I purchased a set of the Cruiser Series control arms for my Jeep Jk based on postive reviews from different Jeep Facebook pages. Ordered and 2 days later realized they had the very same exact arms on sale in the overstock section. Called them up and they refunded me the savings from my original purchase. Amazing, honest service. Can't wait to get them installed. Keep up the good work guys.

These guys are great. You can get them on the phone for support. This important and is not always the case with other custom parts builders. Their control arms are bomb proof and offer plenty of options. You can get real genuine Currie Johnny joints without paying the price for Currie arms.

After ordering an upper and lower adjustable control arm kit manufactured by CORE 4X4 from a jeep parts distributor who's intials are E.T., they came with 3 of the threaded ends missing. After over 2 months of phone calls and emails to this E.T. company nothing was resolved. I finally decided to call CORE 4X4 myself and tell them my dilemma. I spoke with a very personable and professional gentleman named Korby, who is one of CORE 4X4's representatives, after a brief discussion of what I went thru he simply asked me for a picture and some measurements and the items I was missing and asked if I could cover ONLY the cost of shipping and I had my missing parts in exactly 1 weeks time. This company not only builds all it's parts in the U.S.A., they stand behind their products with great customer service and life time warranty. My experience with this company and their Rep Korby was fantastic. I would definitely recommend CORE 4X4 to anyone who needs parts for any 4x4 projects. You just can't beat their quality and service.

Finally a company with a great product and customer service to match. I changed my order last minute from short arms to long arms. The lift is extremely well built. Korbey was awesome! Highly recommend Core 4x4

Have yet to get to try them but I bought some upper, and then later , lower control arms for my 03 rubicon. The pricing is very fair, so fair I was hesitant to even purchase. When the product came in I was happily mistaken. These are some beefy units with an incredible warranty! I’m very excited! I went with the “Camp”series as I mostly daily it. I have trouble with the shipping at times when I ordered but Corby is quick to notice things and help communicate the solution. Looking forward to buying more parts!

Ordered a control arm and track bar kit for my WJ from Core 4x4 on Monday 7/28 and received it today, Friday 8/1. Im not a state or two away, im in CT aka the other side of the country. Communication is phenominal, emails were responded too in an hour or less. Parts arrived well packed, not damaged, and are great quality for my needs. There arent many companies left that service customers as well as Core 4x4 and i wont hesitate to check them out again if i need something else. Well done!

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

CORE 4X4 Company produces/manufactures exceptional products. My rear upper and lower control arms and rear track bar were powder coated custom Fox “Shock Orange” for my 2024 Bronco Wildtrak. OEM looks minimal compared to the CORE 4X4 control arms. Plus they’re adjustable, serviceable and rebuildable. Shipment was very fast and packaging used custom foam wrapped around the arms and heavy duty boxes. Not even UPS could damage. Korby L. was great to work with and responded quickly with emails and product information. Great products. Great people from the State of Utah. All Made in the USA. 5 Stars!!!

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 ! ! !

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.
