Tie rod boot with clamps for a total replacement.
The tie rod boot is a simple protective cover for a very expensive system on your car: the steering rack and linkage. These boots are there to protect the inner ball joint on the tie rod, retain grease for the rack, and prevent outside debris from entering the rack. A ripped boot (sometimes called a gaiter) can spell bad news if left un-repaired. It's an easy replacement, and if done carefully, does not require an alignment after.
This boot kit is manufactured by Rein Automotive (CRP) - an original supplier to BMW for many rubber components, including steering boots. As an OEM it meets all of BMW's original design, fitment, and performance requirements and is TUV approved. OEM parts are the best alternative to more expensive Original BMW parts because they are virtually identical without the inflated price tag. This part has a two year warranty.
