Series and sanctioning bodies require new restraints every two years.

Posted on July 13, 2017

Safety restraints take a lot of abuse while in use in a race vehicle especially those on dirt and off-road racing. Think about all of those bumps you feel lap after lap while racing and the g-forces on your body in the corner. Your restraint system is what keeps you strapped tightly into your seat and has a lot of pressure on it to hold you into your seat.

Restraints should be maintained and inspected after every event for wear and should be replaced or rewebbed every two years. With all of the dirt, dust and even sunlight hitting the restraint system, the elements take a big toll on the restraint fibers. Below is a chart from the SFI Foundation to show the breaking strength of webbing over the course of 24 months.

This isn’t saying that belts are not made to withstand the demands of motorsports because in reality, they are held to a very high standard but when you factor in environmental elements and the harsh g-forces put on them during racing, you can understand why they need to be replaced and rewebbed at least every 2 years. Only the original manufacturer can reweb belts.

Racing series and sanctioning bodies across American have changed their rules to reflect the SFI16.1 standard restraints in either 2 inch or 3 inch wide belts. Restraints are now labeled with date of manufacture as of 2017 whereas before 2017, they were punched. This makes is much easier for officials and drivers to know when their belts will be out of date.
