Front Outer CV Joint Boot Kit, Rein - E46 325xi/330i, E53 X5

The CV joint boot is a simple protective cover for a very expensive system on your car: the axles or half-shafts. These boots are there to protect the inner constant-velocity (CV) joint on the inner or outer end of the axle shaft, retain grease for the rack, and prevent outside debris from entering the joint. A ripped boot (sometimes called a gaiter) can spell bad news if left un-repaired. If caught soon enough the joint may be saved and avoid a much larger repair bill.

This is a CV boot manufactured by Rein Automotive - an original supplier to BMW for many systems and components on your car. As a part manufactured to OEM specs, it meets all of BMW's original design, fitment, and performance requirements and is TUV approved. OEM-type parts like Rein 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.
