Essential Protection for Your Lifted Jeep

Upgrading your 2007-2018 Jeep Wrangler JK/JKU with increased suspension flex and lift? Ensure your rig is protected from over-compression damage with CORE 4X4 Front Bump Stop Extensions (J-JK-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.

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 Durable 6061 T6 Aluminum – Machined from high-strength 6061 T6 aluminum, providing excellent durability and corrosion resistance. Lightweight design ensures minimal impact on suspension performance.
  • 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.

Phenomenal company - very rare to come by in the automotive industry. Also very impressing. Let me start here. I got a set of yellow sway bar end links for my 19 ram DT (new body style) and let me tell you, I’m hooked. For numerous reasons. One the craftsmanship behind the product is unmatched for sure for without breaking the bank. 2ndly, they stand behind their product. Had a very minor issue and it was resolved in a blink of an eye!!! Insane. Just because of what i listed above i will forever spend my money with core 4x4! And i think you should too! I have no affiliation at all with this company besides being a consumer. I will be ordering my yellow UCAs and the rest of my rear suspension from them here shortly! Korby on the other hand. The representative that helped me went above and beyond FAST. I hung up the phone with him, and with in no lie 3 minutes he was calling back with an answer. GREAT GREAT GREAT customer service, Korby you and core 4x4 are what give us hope in the car community! With much love and great health to you all!!

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.

Great long arm kit with everything else I needed as well! They worked with me to ensure that I was getting an upgraded components kit just like I wanted. Fast shipping with some of the best packaging that I have ever seen. Nothing was scratched or missing and this kit is even more impressive than the videos or website can show. Powder coating looks great with no issues. I would highly recommend CORE 4x4 to anyone looking for a great quality kit.

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!

2022 I ordered a 2023 Jeep Wrangler Rubicon in High Velocity yellow. Without any hesitation I knew I was going with Core 4x4’s 16pc Camp series suspension, powder coated in yellow. Compliments were a given from any and everyone that looked under my jeep. So beefy, I may have left some yellow paint on the rocks from Maine to Florida, but no bends or breaks. Customer service has been perfect each and every time I have needed something. Their warranty is top notch! Their communication is also wonderful. Might upgrade to the Crawl Series control arms where the Johnny joints are on both sides. Great all around company and a great team to troubleshoot your issue and come to a conclusion. Nothing bad to say about this company. Just love this suspension.
