Jounce Bumper and Bellows

The durable plastic bellows in this KYB Strut Boot Kit are designed to cover the entire strut shaft, acting as a barrier against dirt, dust, sand, and salt. These contaminants can cause abrasive wear to the polished shaft, upper seal, and bushing, leading to premature strut failure. By preventing these elements from entering the strut assembly, this boot kit can help extend the life of your struts.

Included with the boot is a poly foam travel-limiting bumper. This bumper is specifically designed to prevent the strut from bottoming out during heavy compression, which also helps protect other suspension components from damage caused by extreme movement. This kit is a straightforward way to keep your front struts protected and functioning properly.
