The steering stabilizer that your Jeep Wrangler JK drove off the lot with is a wimpy factory design and is undersized if you upgrade to larger wheels and tires. The steering stabilizer plays a critical part in the steering and handling of your Jeep by absorbing vibrations and jolts from bumps and obstacles in the road or trail. Rough Country offers multiple upgrade options, including single or dual setups, but the Vertex Pass-Through Steering stabilizer is the ultimate choice.Rough Country's Vertex Pass-Through features an innovative design that allows a massive 16mm chrome-hardened piston rod to pass entirely through the stabilizer body. This allows positive pressure on both sides of the piston, offering a handling experience that traditional stabilizers cannot match. This stabilizer also features a piggy-back reservoir to increase fluid capacity and keep a cooler operating temperature, this is critical to provide sustained performance while traveling the most demanding terrain.\A durable brushed steel body, red seals, and black aluminum accents make this stabilizer an excellent looking upgrade for any Jeep Wrangler JK. It's easy to install, with a 100% bolt-on installation process installed in a home garage with common tools. No need to jack up the vehicle, just bolt into place.
