Boot kits protect a joint in the car that would be destroyed by dirt, sand and other particles if left exposed, even under normal conditions so it's important that they be properly maintained and in good condition. Rein Automotive provides application specific power steering boot kits that come guaranteed to fit the first time.
CAPA Certified or NSF Certified parts bear the seal of independent, third party organizations guaranteeing fitment and quality equal to original equipment. These parts may be required if your insurance company is paying for the repair.
