Detailed Product Overview

Rein BKN0100R is a CV boot kit engineered for the front inner position on BMW X5, 325xi, and 330xi applications. For vehicles such as the 2000-2006 BMW X5 front inner axle and the 2001-2005 BMW 325xi and 330xi front inner axle, this kit supports a proper CV joint rebuild by replacing a damaged or deteriorated boot before contamination can damage the joint. The design follows OE specifications and includes OE grease to support correct reassembly and lubrication. This part cross-references BMW OE numbers 31607507403 and 31607565315 for the same application.
