STOP BUYING SEATBELT TENSIONERS! Repair the originals for less. We DO NOT repair seatbelt tensioners but we do have the parts so you can "do it yourself." We do sell the replacement parts for customers who send us their airbag computer modules for repair. Most seatbelt tensioner replacement parts are only $15. For more details send an email to: firstname.lastname@example.org or call (888) 439-0698.
