Have you seen the factory rear sway bar end links on your Wrangler or Gladiator? They leave a lot to be desired in terms of rigidity for sure. Especially as you're using your Jeep in offroad situations, the axles will articulate causing the sway bar which ties the axle to the frame to twist, and the only thing that really ties everything together are the end links. Its fairly common in these situations that the stock end links will either bend or completely snap. While these situations won't stop you from getting off the trail by any means, it renders your sway bar inoperable, causing excessive body roll (if it did completely break). Instead of fretting over your stock end links, upgrade yours with a set of Rock Krawler's heavy duty, adjustable, and greasable end links. These are made from heat treated, zinc plated chromoly and feature injection molded, thermal elastomer bushings for a nice quiet ride. For JL Wranglers, these will work with 1.5"-4.5" of lift, and on JT Gladiators 1.5"-3.0" of lift.
