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 Full Bump Stop Extensions (J-JK-C-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 – Front extensions crafted from lightweight, high-strength 6061 T6 Aluminum for corrosion resistance and longevity. Rear extensions made from heavy-duty 3/16” steel, ensuring maximum strength in extreme conditions.
- 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 – Rear installation is simple bolt-on, utilizing existing bump stop mounts. Front installation requires removing coil springs and factory rubber bump stops, then bolting the extensions in place before reinstalling.
Precision Fit for Any Suspension Setup
Our bump stop extensions come in a range of sizes to accommodate various lift heights and suspension setups, ensuring proper suspension function without sacrificing performance.
Two-Stage Powder Coating for Maximum Durability
Every 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.
