Harness FAQ

What certifications do Simpson harnesses hold?

All Simpson racing harnesses and nets are SFI or FIA approved and dated. Their harnesses are not DOT approved. Simpson sell an extensive selection of racing, off-road and aviation harnesses.

How often should I inspect and/or replace my harnesses?

Simpson recommend replacing your harnesses every 2 years. This is a requirement for most sanctioned racing.

You should inspect your belts before every use. Replace belts that have nicks, cuts, excessive wear, fraying and/or have been exposed to harmful chemicals or the environment.

Proper harnesses are a very important factor in safety. Replace any belts that experience a crash or anything other than normal use. Do not use the harness system ever again, even if it appears OK.

Again, most sanctioning bodies require racing harnesses be replaced 2 years after the date stamped on the SFI tag. Consult your sanctioning body for more information.

Do you re-certify harnesses?

No. First priority is your safety and we do not believe this is a safe practice.

How should I clean my harnesses?

Use a mild detergent and soft cloth. Never use solvents or harsh chemicals.

What’s the advantage or difference to “pull up” or “pull down”?

What you use is a matter of personal preference and the equipment you are using. For example:

• Does the belt go through the seat?
• Will you adjust it, or will someone on the crew?
• What hardware works best with your set up: bolt-in, floor mount or wrap around?

The “pull up” belts are 62” in length. The “pull down” belts are 52” in length. (Inches are in reference to the lap belt.)
