All Keizer Sprint Wheels are manufactured in the historically rich racing state of Iowa. All Keizer Sprint wheels are CNC cold spun and are double heat treated to give us unmatched strength. Our double wall outer rolled lip combined with our unique wheel designs give us that Keizer edge. Our cold forged billet center brings this wheel to a new level of excellence. This champion of the scale outdoes all others with its strength to weight ratios. Its ridged design gives it the ability to outperform in strength with the lightest of wheel components.
