Essential Protection for Your Lifted Jeep

Upgrading your 2018-Present Jeep Wrangler JL/JLU with increased suspension flex and lift? Ensure your rig is protected from over-compression damage with CORE 4X4 Front Bump Stop Extensions (J-JL-F-BSK). Factory bump stops become inadequate as lift height increases, which can lead to tire-to-fender contact, frame stress, and component damage. These extensions correct bump stop engagement, preventing costly issues while maintaining optimal suspension travel.

What's Included?

  • Front Bump Stop Extensions – 6061 T6 Aluminum
  • All Necessary Hardware for Installation

Key Features and Benefits

  • Prevents Over-compression Protects Components – Properly limits suspension travel to prevent tire contact, fender damage, and excessive stress on suspension components.
  • Lightweight, High-Strength Aluminum Construction – Machined from 6061 T6 Aluminum, providing exceptional strength without unnecessary weight. Corrosion-resistant and highly durable, ensuring long-lasting protection in extreme conditions.
  • Straightforward Installation – Simple bolt-on process, utilizing existing factory mounting locations for a seamless fit. Includes all necessary hardware for an easy and secure installation.

Precision Fit for Any Suspension Setup

Available in multiple sizes to accommodate various lift heights and suspension setups, ensuring proper bump stop engagement without sacrificing performance.

Two-Stage Powder Coating for Maximum Durability

Each component undergoes a zinc primer base coat for corrosion resistance, followed by a top coat available in 10 colors, allowing you to customize your Jeep while protecting against rust and wear.

Proudly Made in the USA

Manufactured at our Orem, UT facility, we maintain strict quality control and support local suppliers, ensuring rugged durability and premium craftsmanship.

In Conclusion

Great company, who worked with me on shipping parts to arrive in time for a show. When I explained my concern they went above and beyond to make it happen. Quality of the parts is top notch.

I have nothing but good things to say about Core 4x4. I have the crawler series on my JKU and we take it all over the place. These parts handle everything we throw at them.

Best control arms I have installed on any of my builds. After running every major manufacturer, Core 4x4 is on par or better than all the high-end companies at a fraction of the cost. Lifetime warranty is the cherry on top.

Korby and the rest of the team at Core 4x4 know there stuff and answered my question in a timely manner. They even were able to quick ship a re-build kit for me so I could get my truck back on the road- Thanks!

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.

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.

Excellent, strong, and durable products—perfect for both on-road and off-road applications. The customer service is outstanding—friendly, knowledgeable, and extremely helpful with understanding installation and ensuring I got exactly what I needed. I would definitely order again. Top-notch company with high-quality products made right here in the U.S.A.

The customer service is first class. I had an issue with a track bar I installed on my F350. I don’t have any other Core 4x4 parts yet, but with the way I was treated, I know their parts are well done, because they went above and beyond to make sure I was made whole. They wouldn’t be in business if they had to take care of a lot of people like they took care of me. Will definitely be back when it’s time to build the Jeep!

First and foremost would like to say that Core4x4s customer service is top notch and they definitely stand behind their warranty on products! Highly recommend using them for any of your off road needs! It’s rare to find a company now a days that backs their products and they do! Had a few issues with mounts and control arms and they handled it without hesitation! Thank you!
