“Rockland Standard Gear’s Tranzilla Magnum 6-speed gearbox played a key role in setting the NASA ST2 track record at Pitt Race, and helped me win my past SCCA  Kryder Regional and V8 Stock Car North GT-1 championships. The RSG special close-ratio gear set provides the perfect gear spacing for my LS1-powered 2003 Mustang. The shift quality and reliability are just amazing. Thanks Rockland!”
