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.
