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.

Upgrade Your Jeep’s Suspension for Superior Handling and Off-Road Performance

Take control of your Jeep Wrangler TJ or LJ (1997-2006) with the Camp Series Front Control Arms Set, designed to enhance on-road drivability and off-road capability. This set includes Front Upper Control Arms and Front Lower Control Arms, providing a complete front-end suspension solution. By replacing factory control arms with this high-strength, fully adjustable set, you’ll restore caster, improve axle positioning, and ensure precise suspension alignment—all crucial for stability, handling, and overall ride quality.

What’s Included in the Kit?

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

Key Features and Benefits

  • Heavy-Duty Construction – Made from 1.75" OD DOM tubing for lower arms and 1.5" OD DOM tubing for upper arms, each with a .313" wall thickness, ensuring maximum durability.
  • Restores Caster for Improved Steering Stability – Lifting your Jeep affects suspension geometry, often leading to unstable steering and increased wander at highway speeds. This kit helps restore lost caster angle, improving high-speed stability and handling precision.
  • Optimized for Lifted Vehicles – Fully adjustable to accommodate lifts from 0 to 6 inches, allowing for precise axle alignment, recentering, and pinion angle adjustment.
  • Superior Articulation and Ride Comfort – Features Rock Jock Johnny Joints at the adjustable end for maximum suspension flex and tapered polyurethane bushings at the fixed end to reduce vibration and enhance ride comfort.
  • Recommended Pairing – For the ultimate front-end suspension upgrade, pair with the Camp Series Front Track Bar (CMP-J-TJLJ-FTB1) to maintain axle centering and further enhance steering stability.

Two-Stage Powder Coating for Maximum Protection

To ensure long-term durability and resistance to the elements, each control arm undergoes a two-stage powder coating process: Zinc primer base coat for superior corrosion resistance. Durable top coat, available in 10 color options, allowing you to personalize your Jeep’s suspension while adding an extra layer of protection.

Proudly Made in the USA

Manufactured in Orem, UT, our Camp Series Front Control Arms Set is built to the highest standards of American craftsmanship, ensuring exceptional strength and performance.

Optional Hardware Upgrade

Designed for bolt-on installation using factory hardware. If your existing bolts are rusted or difficult to remove, optional Grade 8 hardware kits are available separately to simplify the installation process.

In Conclusion

The Camp Series Front Control Arms Set (CMP-J-TJLJ-FS4) is a significant upgrade over factory components, helping to correct caster angle, recenter the front axle, and optimize suspension articulation. Whether you're daily driving, hitting the trails, or rock crawling, this kit delivers superior performance, handling, and durability.

Upgrade today and experience the difference American-made quality makes!

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.

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.

Bought a new 2019 Ram 1500. Had bad rear wheel hop since new, got all four core 4x4 control arms and it fixed the issue. Thanks

I just finished installing the Peak 2.0 Front Suspension system with the Core 4x4 Blue Tacoma Rear Suspension system on my 2024 TRD Offroad Premium Tacoma. The two upgraded suspension systems really made a difference in how the ride feels, whether we’re off-road or on the road. A big thank you to Korby and the team at Core 4x4 for their support and for getting the shipping sorted out so quickly!

Had a great experience with Core 4x4, I desperately needed a custom track bar and found out just a couple days before Easter Jeep Safari. Spence was a huge help and made it happen with plenty of time to spare. Their parts are top notch!

First time buying from Korby @ Core 4x4 and it’s being nothing short of a great experience. I bought the non adjustable Trail kit for my 5th Gen Ram 1500 with a 2” lift. The welds look great, nice powder coat finish and quality bushing. Had some trouble fitting the grease nipples due to the powder coating but a thread tap would fix that. They fit easily and perform great. I felt the improvement straight away. No more wheel hop on hard acceleration which was my main reason for the purchase. I was missing some smaller bushings needed for the 5th Gen and Korby’s custom service was on point, with responsive emails and mailing out the missing parts straight away. Very happy with their products and customer service. Highly recommended company👌🏽

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.

I meant to put this reviewing about a year ago now, but ever since I’ve had the core 4 x 4, upper and lower control arms on my 2017 ram 1500, they have worked flawlessly leave been on many offering chips, and I’ll definitely be buying new accessories from them in the future and their new upper control arms that they’re offering for all of the ram trucks. Fantastic customer service fantastic health very automotive, off-road, friendly, and any aftermarket thing for your truck or SUV that they currently have!

Exceptional customer service. All my questions were asked in a timely manner and parts were replaced when an error occured. I encourage people to make purchases due to their exceptional quality products, but also because of their customer service. Will make additional purchases in the future.
