Essential Protection for Your Lifted Jeep

Upgrading your 2018+ Jeep Wrangler JL with increased suspension flex and lift? Ensure your rig is protected from over-compression damage with CORE 4X4 Rear Bump Stop Extensions (J-JL-R-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.
  • Premium Construction for Maximum Durability – Crafted from heavy-duty 3/16” steel, ensuring superior strength in extreme conditions. Laser-cut for a precise fit and long-lasting durability.
  • Offset Design for Improved Alignment – Unlike traditional puck-style extensions, our offset design maintains correct bump stop alignment, ensuring even load distribution and reducing stress on the mounts.
  • Straightforward Installation – Simple bolt-on process, utilizing existing bump stop mounts for a hassle-free install. Includes all necessary hardware for a complete and secure fit.

Precision Fit for Any Suspension Setup

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

I needed some parts and had to replace 1 lower control arm and their customer service is great. Helped with answering my questions and got parts shipped quickly.

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!

Beefy parts made and painted well, very fair pricing for what you get, and fantastic customer service to boot. Easily my favorite place to get suspension parts.

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!

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.

Purchased a set of Trailing arms for my Ram 1500, quality is first class. I bought the ones with the Jonny Joints for more articulation and it appears from the construction I should get a lifetime of use, Zerk fittings are an added plus. Would defiantly recommend, and the the service team answered all of my questions.

2001 Wrangler TJ- i have purchased all front/rear upper/lower control arms. Front track bar and rear track bar. Quality is excellent and extremely durable you can tell its built to last. Bent a bolt on the front track bar and called and spoke with Spence. He immediately sent me out new hardware plus some! Product is amazing but what really separates companies apart is their service and these guys are second to none. Thank you all!
