Conquer Any Terrain with CORE 4X4’s Crawl Series Lift Kit

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.

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)

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.

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!
