Elevate your off-road experience with CORE 4X4’s Crawl Series Lift Kit, designed specifically for Jeep JT Gladiator models. Engineered for extreme off-roading, this kit empowers you to conquer the toughest trails with unmatched strength, precision, and durability.

Key Features Benefits

  • 4.5" Lift for Extreme Off-Roading – Gain significant ground clearance to tackle rugged terrain and accommodate larger tires, ensuring you overcome obstacles with ease.
  • Heavy-Duty Control Arms – All 8 Crawl Series adjustable control arms ensure maximum strength and precise suspension articulation, built to withstand extreme off-road conditions.
  • Adjustable Track Bars – Front and rear Crawl Series track bars maintain optimal axle alignment, providing superior stability and control in aggressive off-road situations.
  • Triple Rate Coil Springs – Delivers superior ride quality and improved suspension travel, adapting to varying terrains for enhanced comfort and control.
  • High-Performance Shock Absorbers – Matched to the lift height, these shocks provide exceptional damping control, ensuring a smooth and controlled ride over rough terrain.
  • Extended Brake Hoses – Accommodates increased suspension travel while ensuring consistent and reliable braking performance during extreme off-road use.
  • Raised Rear Track Bar Bracket – Corrects roll center and enhances handling for improved suspension geometry and stability.
  • Front and Rear Extended Sway Bar Endlinks – Enhances handling and stability, reducing body roll and improving control.

Important Notes

The CORE 4X4 Steering Kit add-on is over-the-knuckle and requires minor drilling for installation. Necessary hardware and an additional front track bar relocation bracket are included.

Lift heights are based on Rubicon models with average builds (bumpers, winch, spare tire) other models and builds will achieve slightly different lift heights.

For Mojave owners: If you would like to retain the factory shocks, select the optional shock extensions before adding to cart. Factory bump stops are not affected with this kit. 

A new front driveshaft is required with our 4.5" JT Lift kit. The factory driveshaft will be over-extended and cause damage. We have two options available to add to your kit, or order your own, but do not use your factory shaft with this kit!

Lift kits are sourced from multiple trusted partners and will ship from different locations.

Durable Two-Stage Powder Coating

To ensure long-lasting durability and corrosion resistance, all steel components undergo a two-stage powder coating process. A zinc primer base coat provides rust protection, while a durable topcoat is available in 10 color options, allowing you to personalize your build.

Made in the USA

Proudly designed, engineered, and manufactured in Orem, UT, ensuring top-tier craftsmanship, strict quality control, and long-term reliability.

Tire Fitment

  • Fits up to 40" tires with stock fenders.

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!

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.

Beefy parts made and painted well, very fair pricing for what you get, and fantastic customer service to boot. Easily my favorite place to get suspension parts.

First off, I wish I knew about them sooner. The customer service is top tier. The response time is about 30 min no waiting 1-3 days to get a response. The parts are heavy-duty and look amazing. The packaging is perfect, I can't wait to hit some trails. Thanks Core4x4

Have full upper/lower CA set on both front and rear axles on a 96 ZJ. These are the rubber bushing sets not joint sets. I have beat the hell out it in the Nevada desert for 2 years and has been great. I don’t go fast but I do articulate suspension a lot. Super solid and haven’t any issues. Just inspected the entire set recently due to some banging under it. Turns out the banging is lower rear shock bushings. Inspected each CA along the way nothing. Aside from dirt and obviously winter roads and what not still in excellent condition, bushings are solid like the day they were installed. I’ll add that I’m about tapped on a short arm at 4.25(less with settle) so the front CA’s get beat on just from that, still they’re like new. Paint is great condition, this set is red. I would definitely buy again. Another plus for me, Utah isn’t local necessarily, but it’s nice to support businesses closer to me.

Had a worn out set of rear upper control arms on my TJ. These were old rubicon express long arms. can’t buy replacements and no one makes a direct fit replacement. Talked with Korby at core off road sent some measurements and photos and a week later new arms showed up. Packaging was perfect fit was perfect. Would highly recommend giving these guys a call.

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.

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.
