Achieve Superior Off-Road Articulation and Stability

Elevate your Jeep Wrangler JL’s suspension performance with the Crawl Series Front and Rear Sway Bar End Link Set (CRL-J-JL-ELS4). Designed for both Rubicon and non-Rubicon models, this set delivers maximum articulation, enhanced handling, and superior durability. With RockJock Johnny Joints at both ends, these sway bar end links provide bind-free movement, ensuring optimal performance during extreme off-road conditions while maintaining on-road stability.

Key Features and Benefits

  • Unmatched Articulation: Featuring Johnny Joints at both ends, these sway bar end links allow for maximum flexibility and bind-free movement, enabling your suspension to perform flawlessly on the toughest terrains.
  • Optimized for Rubicon Sway Bars: Designed to integrate seamlessly with Rubicon sway bars, these links eliminate binding issues and enhance articulation. They are also fully compatible with non-Rubicon sway bars for versatile performance.
  • Custom Fit for Lift Heights: Built at fixed lengths to match your vehicle’s specific lift height, this set ensures precise suspension alignment and proper sway bar operation for standard or lifted Jeeps.
  • Durable, Rebuildable Construction: Made from .75” OD Cold Rolled Steel, these sway bar end links are fully greaseable and completely rebuildable, ensuring a long, quiet service life and exceptional durability under extreme conditions.

Two-Stage Powder Coating

Every sway bar end link undergoes a rigorous two-stage powder coating process to maximize durability and corrosion resistance. Zinc primer base provides robust rust protection. Topcoat available in 10 customizable colors adds an extra layer of defense and a personalized touch to your suspension system.

Made in the USA

Proudly designed and manufactured in our Orem, UT facility, the Crawl Series Front and Rear Sway Bar End Link Set exemplifies CORE 4X4’s commitment to American craftsmanship. By managing production in-house and sourcing materials locally, we deliver superior quality and support the local economy.

Optional Hardware Upgrade

Installing the Crawl Series Sway Bar End Links is straightforward with all necessary hardware included. For proper fitment, some widening of the end link mounts may be required. Simply bend the mount outward slightly during installation, and tightening the bolt will realign the mount to the correct position. This process ensures a secure fit and optimal performance.


  • Vehicle Fitment: Jeep Wrangler JL 18+ – Enhances stability, reduces body roll, and improves handling for both off-road and daily driving.

  • CORE Advantage: Johnny Joints at both ends provide extreme articulation, allowing full suspension movement without the need for quick disconnects when paired with a Rubicon front sway bar.

  • Built to Length: Custom-built to match your exact lift height, ensuring proper sway bar function and alignment for both stock and lifted setups.

  • Construction: Made from .75” OD cold-rolled steel, fully greaseable and rebuildable for long-lasting performance under extreme conditions.

  • Two-Stage Powder Coating: Zinc primer base and top coat available in 10 vibrant colors protect against corrosion and allow for personalized styling of your rig.

  • Warranty and Origin: Proudly manufactured in the United States, our product includes a lifetime warranty on all non-wear items, providing you with confidence and peace of mind in your purchase.

I bought the 16pc Cruise Series Adjustable Control Arm, Track Bar, Steering, End Link Kit to replace a worn budget 4" lift on my used JKU. These are top quality parts; very solid. Customer service is unsurpassed. They even matched prices on my order placed before the tax day sale. I made an error in ordering a drag link flip kit; they were quick to help me fix this too. There's peace of mind knowing these components are made in the USA. Thank you. 👍👍

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.

I couldn't have been more excited for the initial unboxing of these new Core 4x4 UCA's! They appear to be so well built and just a true quality product. Installation was a breeze and the initial testing with the forklift appears to have given me some additional flex with less binding on the rest of the components now that the geometry is back properly aligned. Time will tell how they hold up on my near future off-road adventures but I don't have any doubt that they are up to the task!

I purchased a set of the Cruiser Series control arms for my Jeep Jk based on postive reviews from different Jeep Facebook pages. Ordered and 2 days later realized they had the very same exact arms on sale in the overstock section. Called them up and they refunded me the savings from my original purchase. Amazing, honest service. Can't wait to get them installed. Keep up the good work guys.

Have yet to get to try them but I bought some upper, and then later , lower control arms for my 03 rubicon. The pricing is very fair, so fair I was hesitant to even purchase. When the product came in I was happily mistaken. These are some beefy units with an incredible warranty! I’m very excited! I went with the “Camp”series as I mostly daily it. I have trouble with the shipping at times when I ordered but Corby is quick to notice things and help communicate the solution. Looking forward to buying more parts!

Small business, family owned, made in the USA, lifetime warranty. Purchased Tier 3 control arms and rear track bar for a 2006 Jeep LJ. Simple website and easy to contact over phone and email. I had some technical questions and they were happy to answer them. They allow local pickup and were built to order same week. The order was wrapped and ready when I walked in and even gave a tour of the shop. They abrasive blast all raw materials to achieve a better surface profile for powdercoat to adhere and create a smooth, durable finish. I also noticed several CNC machines and a robotic welder they use for all their parts. A small outfit with a robotic welder? Their concern for quality is obvious and it shows in the parts they make. Very impressed. Happy to do business with these guys.

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.
