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.

The Ultimate Hard Component Suspension Solution

Upgrade your Jeep Gladiator JT (2020-Present) with the Cruise Series 10-Piece Kit, an all-in-one suspension upgrade designed to eliminate caster deficiencies, driveline vibrations, wandering, rut-following, and even death wobble. By replacing all key hard components, this kit ensures proper alignment, axle centering, and improved ride quality both on and off the road.

What’s Included in the Kit?

  • Cruise Series Front Upper Control Arms (CRS-J-JT-FU2)
  • Cruise Series Front Lower Control Arms (CRS-J-JT-FL2)
  • Cruise Series Rear Upper Control Arms (CRS-J-JT-RU2)
  • Cruise Series Rear Lower Control Arms (CRS-J-JT-RL2)
  • Cruise Series Front Track Bar (CRS-J-JT-FTB1)
  • Cruise Series Rear Track Bar (CRS-J-JT-RTB1)

Each component is built from heavy-duty steel tubing and features polyurethane bushings, delivering superior strength, adjustability, and long-lasting durability to tackle any terrain.

Key Features and Benefits

  • Eliminates driveline vibrations – Adjust rear pinion angle for a smoother ride and reduced wear on driveline components.
  • Corrects caster deficiencies – Regains proper caster angle, improving steering precision and eliminating wandering.
  • Centers axles properly – Ensures correct front and rear axle positioning, critical for lifted vehicles.
  • Designed for 0 to 6 inches of lift – Fully adjustable control arms and track bars allow for precise suspension tuning.

Built for Durability

Heavy-duty steel construction and polyurethane bushings provide long-lasting performance.

Recommended Pairing for Ultimate Performance

Combine with the Cruise Series Front Rear End Link Set (CRS-J-JT-ELS4) to create a complete high-performance suspension system.

Durable Two-Stage Powder Coating

Each component undergoes a zinc primer base coat for corrosion resistance, followed by a top coat available in 10 colors for a personalized look.

Optional Hardware Upgrade

Designed to reuse factory hardware, with optional Grade 8 hardware kits available separately for rusted or worn-out bolts.

Upgrade Today!

If you're lifting your Gladiator JT, the Cruise Series 10-Piece Kit provides a complete suspension solution, eliminating caster issues, death wobble, wandering, driveline vibrations, and axle misalignment. For the ultimate upgrade, pair it with the Cruise Series End Link Set to create a fully optimized suspension system. Upgrade today and experience precise alignment, smoother handling, and unbeatable off-road durability!

Notes: Some, (not all) factory axle mounts need to be "clearanced" to accept our larger bar. If needed, it is only a minor amount of trimming to be done. This applies to the front track bar only. Please see our Youtube channel for a video addressing this.

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.

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.

Excellent service, Prompt responses when needing technical assistance, Amazing looking parts that fit excellently. I would recommend them to anyone looking for suspension components. Also very well packaged when we received the shipment, which means no damage from shipping company!! We went with the Crawl Series double adjustable kit and it definitely looks killer on our build!!!

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)

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!

In September 2025, we visited CORE 4x4 in Orem, Utah. CORE 4x4 makes control arms and other similar parts that stiffen the suspension of an off-road 4x4 vehicles, so that the off-road vehicles can travel on more rugged terrain. CORE 4x4 used to share this building with another business, and since this other business has moved elsewhere, CORE 4x4 will continue to expand and grow their business. Good for CORE 4x4 to be a growing company and to expand into the vacant part of the building.

I ordered a part for my 03 Jeep TJ and all I can say is wow! Korby at Core 4x4 is a total rockstar!! There was a glitch with my payment and within minutes, Korby reached out to me to get it fixed, then sent my receipt with the tracking number. I lost the number and reached out to him during the Holidays and got a rapid response with the number again. I can’t say enough about the customer service and the quality of parts. Thank you!!

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.

Great Experience. I wanted to make changes to my order and Korby was more than willing to work with me to get everything corrected. Hope to deal with these guys again in the future.
