Essential Protection for Your Lifted Jeep
Upgrading your 2018-Present Jeep Wrangler JL/JLU with increased suspension flex and lift? Ensure your rig is protected from over-compression damage with CORE 4X4 Front Bump Stop Extensions (J-JL-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.
