Detailed Description

Monroe 63633 is a replacement strut boot kit for front suspension applications that need renewed rod protection after the original boot or bumper has worn out, cracked, or torn. By covering the exposed strut rod, the boot helps reduce direct contact with dirt, moisture, and debris that can accelerate wear on the strut assembly.
