Effective Jan. 1, 2005, Y-type driver restraint system was no longer certifiable under the SFI Spec 16.1. However, existing Y-type belts with current dates of manufacture may be used until its two-year expiration period, which after that expiration date, the Y-type driver restraint system will not be certified with an SFI specification.
Racers and technical officials should be aware that V-type harnesses are certifiable to SFI Spec 16.1.
There has been some confusion regarding the difference between Y-types and V-types.
A Y-type harness consists of a single strap of webbing ending in a single attachment point while a V-type harness also has a single end attachment, but it is a continuous length of webbing that loops through the end hardware and over both shoulders, effectively providing a double belt.
If you have any further questions, contact your Division Technical Director or the NHRA Technical Department.
Below, the Y-type and V-type harnesses are illustrated.
