The Science Behind Seat Belt Deployment

If an accident occurs, the airbag module sends a signal to the seat belt pretensioners, which tighten the belt by triggering a small charge that removes any slack. This locks the seat belt in place. To return the belts to proper working condition, they need to be rebuilt and recharged. Our team provides this service quickly and includes a lifetime warranty.

We also repair seat belts that have stopped working properly due to age, dirt, or grime. Over time, seat belts can wear out, jam, or lose effectiveness, reducing safety. Send your seat belts to us, and we’ll restore them to full working order.

FAQ

Have questions? We’re here to help! Browse our most frequently asked questions below and if you don’t find the answer you need, contact our support team anytime.

My driver and passenger seat belts are stuck and locked after an accident and the airbag light is on. How does this service work?

We use OEM parts to fully rebuild the retractor and replace the igniter/inflator in the pretensioner to make it work like new again! This will reset the airbag light after an SRS airbag module reset.

Do you replace the original seatbelt color webbing if it has been cut?

Yes! For webbing replacement, we can either match your existing color or let you choose a custom one. We’ll even re-stitch all the original tags!

How do I remove my seat belt for repair?

Most seat belts can be removed by removing the trim and unscrewing the bolts that attach the belt to the car’s frame. There are plenty of YouTube videos showing the process, and we’re also happy to provide guidance if you need help.

How can i tell the difference between single, dual and triple stage seat belts?

Seat belts come in three types: Single Stage, Dual Stage, and Triple Stage. The type is determined by the number of plugs or wires: Single Stage has 1 plug, Dual Stage has 2, and Triple Stage has 3.
