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.

Maximize Your Jeep Gladiator JT’s Suspension Performance with the Crawl Series Complete Kit

Designed for ultimate on-road comfort and extreme off-road performance, the Crawl Series Complete Kit for Jeep Gladiator JT provides unparalleled control over your vehicle’s suspension. Whether tackling rugged trails or cruising on highways, this all-inclusive kit ensures superior articulation, adjustability, and durability to meet any challenge.

What’s Included

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

Key Features and Benefits

  • Unparalleled flexibility and articulation – Johnny Joints at both ends of every control arm and track bar provide maximum articulation and smooth movement across the most challenging terrains.
  • Incredible drivability – Improves road handling by correcting factory suspension deficiencies, eliminating wandering, flighty steering, and following ruts for a smooth, controlled ride.
  • Superior construction – Built from high-strength DOM tubing with a 5/16” wall thickness, these components withstand the harshest off-road environments while maintaining reliability on the road.
  • Enhanced suspension geometry – Re-centers axles, optimizes caster and pinion angles, and corrects alignment issues for maximum stability and balanced performance.

Elevated Control and Stability

The Crawl Series Complete Kit is engineered to tackle common suspension challenges, such as death wobble, axle misalignment, and poor drivability. With optimized alignment and advanced suspension geometry, you’ll experience smoother handling, reduced stress on components, and improved overall control.

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 for straightforward installation using factory hardware, with optional Grade 8 hardware kits available for rusted or stubborn bolts.

Upgrade Today!

Choosing the Crawl Series Complete Kit means investing in unmatched suspension control, off-road flexibility, and on-road drivability. Upgrade your Jeep Gladiator JT today for a game-changing transformation in stability, articulation, and performance!

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.

We have all shopped places where the person on the phone makes you feel like they don't have the time to talk to you the customer or answer your questions. I can tell you first hand that's not Core 4x4. They have the best customer service I have seen so far. They have taken the time to respond to all of my questions in a very prompt and professional manner, taking the time to answer each and every question I have had. Lets put it this way if Core 4x4 sells a product I am wanting for my truck I will buy it from them, I highly recommend Core 4x4.

2022 I ordered a 2023 Jeep Wrangler Rubicon in High Velocity yellow. Without any hesitation I knew I was going with Core 4x4’s 16pc Camp series suspension, powder coated in yellow. Compliments were a given from any and everyone that looked under my jeep. So beefy, I may have left some yellow paint on the rocks from Maine to Florida, but no bends or breaks. Customer service has been perfect each and every time I have needed something. Their warranty is top notch! Their communication is also wonderful. Might upgrade to the Crawl Series control arms where the Johnny joints are on both sides. Great all around company and a great team to troubleshoot your issue and come to a conclusion. Nothing bad to say about this company. Just love this suspension.

I have nothing but great things to say about this company and their customer service. If you like American made products backed by warranty and amazing customer support, this is the company for you. I have a Lexus GX470 and love their rear control arms.

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.

Outstanding experience! I asked Core to build me a set of custom control arms that were larger/heavier than they normally build. They gladly accepted the challenge and turned out an expertly crafted and super strong product ahead of schedule. Fit and finish are excellent. Spence and Cameron were a pleasure to work with every step of the way. And all of this for a very reasonable price. I highly recommend these guys!

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!

Ordered a set of Core 4x4 control arms for my 2006 Jeep TJ. These are some heavy duty quality control arms. Can't wait to get them installed. Great customer service too!

Absolutely incredible family owned business. I asked to pick up my order since I’m local and they came in on a weekend to accommodate. Had to make some adjustments to parts and took the time to make sure it was perfect. Parts are incredible quality. If you have a Jeep, do not hesitate to support this local business.

The parts are a massive improvement over factory. I accidentally ordered the wrong endlinks and they helped me figure out the correct size and sent me new ones. Definitely an awesome store

Installed the full kit on my XJ. Ride quality is night and day better than what I had before. The articulation on the trail is insane. These guys know what they are doing. Already recommended Core 4x4 to everyone in my club.
