This restraint kit includes a SFI approved blower restraint plate, nylon restraint straps covered in silver fire protectant sleeves, black powder coated steel header brackets, and alum. quick release pins. This restraint can fit all 6-71 thru 16-71 roots blowers with the six hole top opening. Opening in the blower restraint plate is 12.250" x 4.00".
Beauty of this restraint is the straps lace into the top plate so it can be used on lots of different height engine combinations and when the SFI tag expires simply call up RBS and order a new set of SFI tagged straps and you are back out to the track without costly shipping back and forth to get new straps sewn on your blower restraint.
