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 Rear Bump Stop Extensions (J-JK-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.
  • Heavy-Duty Steel Construction – Precision laser-cut from 3/16” steel, offering maximum durability and strength. Designed for extreme off-road conditions, ensuring long-lasting protection for your Jeep.
  • Offset Design for Improved Alignment – Unlike traditional puck-style extensions, our precision-machined offset design keeps the bump stop aligned with the factory pad, ensuring even load distribution and reducing stress on the mounts.
  • 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.

Recieved warrenty exchanges for my control arms last night couldnt be happier!!! Lets talk about the arms tho! Great quality arms in multiple styles and colors!!! I purchased the teir 3 short arns for my 98 xj. I can say that they setoff nicely so my 35 inch tires do not rub! As long as you can get a photo or video of broken hardware core will take care of you. The body of the arm is bulletproof. However make sure to maintain and grease the joints regularly as with any greaseable joint and they shouldkast forever. I had a few problems arise a year after purchase and after some troubleshooting spence was able to help get me the correct parts to get back on the road. I recommend this setup to any and all jeepers looking to get away from the stock arm setup. Alltogether i am Very happy with the performace of my control arms!!!! Mechanic and bodyman of 12 years and my first choice for quality control arms!!

I wanted to take a moment and give these guys a shout out, I’ve currently got, for my xj, their adjustable control arms, tier 4 adjustable track bar and adjustable leaf spring shackles. You can always count on a fair price, high quality products, and quick delivery. Keep up the great work guys, will definitely continue to shop with you

Top notch company. Mechanic lost bolts that clamp upper control arms. Korby sent out spare bolts no charge. Best customer service I’ve come across in a long time. Only suspension brand I’ll ever use.
