Tuesday Tech Question


I heard that there may have been a change in the helmet bar rule on Jr Dragsters?

Helmet Bar Harold,

No, there has not been a change in helmet bars in Jr Dragsters since 2008.  The 2012 NHRA Jr Dragster Rulebook states “Helmet bars (3/4-inch OD X .058-inch chromoly tubing or 3/4-inch X .083-inch mild steel, or 1/2-inch X .090-inch flat strap) are required between the secondary upper roll cage hoop and the upper roll cage rear braces on each side of the car.  If the center-to-center distance between the upper roll cage rear braces exceed 6 inches, then an additional helmet bar is required between the back braces.  The helmet bars are to be installed at a height above the shoulder hoop that will keep the driver’s helmet inside of the roll cage.”
