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.
