Tuesday Tech Question presented by Evans Coolant


I’m running a low eight second dragster and I would like to use a head and neck restraint system. I was told I would still need to use my neck collar. Is this correct?


In the 2017 NHRA Rulebook, section 4A, page 8, it states “If SFI Spec 3.3 neck collar is required and driver opts to use an SFI 38.1 head and neck restraint system instead, then SFI Spec 3.3 head sock or SFI Spec 3.3 skirted helmet mandatory.”
