Performance, stability, and quietness when the body of your Wrangler JL moves and flexes – these are what bushings offer, and why it’s important to replace worn-out bushings with super-durable 2018 Wrangler bushings & body mounts. These bushing kits make full use of modern advanced materials, including elastomer bushings which function like rubber at low speeds and polyurethane at higher speeds, offering greater comfort and stability than bushings made from either of the other substances can achieve. Other 2018 Wrangler suspension and bushings components include track bar, control arm, and sway bar bushings, also made from premium cutting edge materials. While these parts are great for replacing degraded and battered OE bushings and mounts, you can also use them as a straightforward upgrade, simply to improve balance and control long before the stock bushings wear out.
