Jounce Bumper

KYB is well-known for making reliable suspension components, and these strut boots are no exception. If you're working on the front suspension of your 2005-2010 Jeep Grand Cherokee or 2006-2010 Jeep Commander, these boots are a smart addition to help protect your investment.

These boots act like a durable plastic bellows, covering the entire strut shaft. Their main job is to keep harmful elements like dirt, dust, sand, and salt from getting into the strut. When those contaminants get past the seal, they can cause abrasive wear on the polished shaft and the upper seal, which can shorten the strut's life. By preventing this, these KYB boots can help your struts last longer. They also include a poly foam travel-limiting bumper. This bumper is designed to prevent the strut from bottoming out, which can protect both the strut itself and other nearby components from damage caused by extreme movement.
