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 Function of Sway Bar End Links

Sway bar end links are essential to your Jeep Wrangler JK's suspension system, minimizing body roll during turns and significantly improving stability and handling. Upgrading your sway bar end links can transform your off-road performance and enhance on-road driving, particularly when tackling rough terrains or carrying heavy loads.

What's Included in the Kit

  • Crawl Series Front Sway Bar End Links (CRL-J-JK-FEL2)

Unmatched Articulation and Maximum Performance

Experience the ultimate off-road upgrade with CORE 4X4's Crawl Series Front Sway Bar End Links. Designed specifically for Jeep Wrangler JK (2007-2018), these sway bar end links deliver unparalleled articulation and superior performance.

Equipped with RockJock Johnny Joints at both ends, they provide bind-free articulation, especially when paired with Rubicon sway bars, and ensure durability for even the most demanding adventures.

Innovative Design and Premium Materials

These sway bar end links are constructed from .75" OD Cold Rolled Steel, combining strength and resilience. Engineered to withstand extreme off-road conditions, they offer excellent stability, responsiveness, and longevity.

Fully greaseable and completely rebuildable, these end links are built to last, providing long-term reliability and quiet operation.

Customized for Your Vehicle’s Height

CORE 4X4 sway bar end links are tailored to your vehicle's lift height for an exact fit. Whether your Jeep Wrangler JK is at standard height or equipped with a lift kit, these links ensure optimal sway bar function.

At the time of order, simply provide your vehicle’s lift height for a perfect match.

Two-Stage Powder Coating for Durability and Style

Every sway bar end link undergoes a rigorous two-stage powder coating process for enhanced durability and corrosion resistance. Zinc primer base coat forms a protective shield against rust. Durable top coat, available in 10 colors, adds another layer of protection and customization.

Proudly Made in the USA

CORE 4X4 takes pride in crafting the Crawl Series in Orem, UT. By manufacturing locally and maintaining complete control over the production process, we ensure the highest quality standards while supporting American industry.

Optional Hardware Upgrade

Installing the Crawl Series Front Sway Bar End Links is simple with the included hardware. Some minor modifications may be required, such as widening the front passenger lower mount slightly. Tightening the bolt will re-align the mount to the correct position for a secure fit.

In Conclusion

Upgrade your Jeep Wrangler JK with the Crawl Series Front Sway Bar End Links and experience enhanced stability, maximum articulation, and long-lasting durability. Built for serious off-roaders, these end links ensure your suspension performs flawlessly no matter the terrain.

Choose CORE 4X4 for unbeatable quality and performance!

Each rebuild kit includes all necessary components to replace and restore wearable parts.

Brand CORE 4X4
Color Black or Blue or Charcoal or Green or LightGreen or Orange or Purple or Red or White or Yellow or Custom Color - Other than what is listed above. Extra charge varies. We will reach out after order is placed.
Series Crawl Series
Lift Size Stock Height or Lifted 1" or Lifted 2" or Lifted 3" or Lifted 4" or Lifted 5" or Lifted 6" or Lifted 7" or Lifted 8" or Custom length or 1/2 sizes (put desired length in the Order Notes)

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.

I recently ordered a set of control arms from Core 4x4, and the entire experience was absolutely top-notch from start to finish. The ordering process was smooth, the parts arrived quickly, and the control arms themselves are extremely high quality—solid construction, great finish, and clearly built to last. I also want to give a special shout-out to Korby, the guy I spoke with during the process. His customer service was amazing. He went above and beyond to make sure I got exactly what I needed, answered all my questions, and made the whole experience stress-free. You don’t see service like that very often these days. If you’re looking for high-quality suspension components backed by truly exceptional customer service, I highly recommend Core 4x4. I’ll definitely be buying from them again.

I purchased the Jeep WJ control arms Camp series over a year ago. Very pleased and impressed. Easy installation and solid build. Bracket broke for rear upper control arm, they redesigned it to be more robust and sent me a new one with hardware, honoring their guarantee!

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

I want to share a truly positive experience. I ordered a car kit consisting of two packages, but unfortunately one was lost during shipping with UPS. The situation could have become complicated... but it didn't. The company manager was extremely helpful and professional: he personally followed up on the situation and did everything he could to resolve the issue, even sending me the package again without hesitation. It's rare to find such attentive and reliable customer service these days. My sincere congratulations on your professionalism and commitment: that makes all the difference.
