RTF Racing Transmission Fluid is specifically engineered to reduce fluid drag for increased power efficiency without compromising component durability. It is made from a combination of specially selected 100% synthetic Group IV/V base oils proving superior shear resistance and extreme temperature stability. RTF is specially formulated to exceed the load-carrying and extreme pressure wear protection properties of higher viscosity GL-5 or GL-6 gear oils. RTF provides anti-score protection for high speed, high load and high torque shock-loading conditions, while allowing smooth operation of synchronizers.

- Group IV/V 100% Synthetic Formula
- Maximizes power throughput
- Reduces gear box temperatures
- Superior level of shock load, EP and wear protection

Recommended for manual transmissions, transaxles and marine outdrive units where an SAE 75W90, 80W90 or 90 is specified. Also replaces SAE motor oil 10W30, 30, 10W40 or 40 where specified for transmissions. Commonly used in circle track (Winston Cup, Busch, modified, stock), road racing, formula, open wheel (Champ Cars, IRL Cars), off road, drag racing, sports compact street and domestic performance street applications. Highly recommended for achieving maximum power efficiency. Excellent for dry sump and fluid drive gear cases. Note: RTF is specifically recommended for Richmond Gear Racing Transmissions.
