Phipps' "Ribbed" series has kind of an "Old School Billet" look to them. Designed to compliment the newstalgia hot rod look. The ribbed design has always stood for a no nonsense hot rod attitude and these pedals fit right in and are very cool. Manufactured from 6061 T6 billet aluminum and show polished. The Gas pedal is fully adjustable and the arms are available as solid assembles or drilled with lightening holes for that hotrod look.
