The Elite IL300-6S is Elite Racing Transmissions’ most popular inline Rear wheel drive 6-speed sequential gearbox, combining high torque capacity, rapid gear changes and a compact motorsport-proven design.
With its big-pitch gearset and 550 ft/lbs torque capacity, the IL300-6S is an excellent choice for a wide range of competition vehicles—from modern circuit and rally cars through to classic race cars requiring a strong, modern sequential transmission.
Typical applications include circuit racing, rallying, drag racing, grass track and specialist competition vehicles.
Sequential gear selection combined with dog engagement gears provides fast, positive shifts and allows clutch-less upshifting when integrated with a suitable engine management system.
High-Strength Motorsport Construction
The IL300 gears are manufactured from high-strength hardening alloy steel and are REM Superfinished as standard.
This finishing process helps reduce friction, improve surface quality and increase durability under demanding motorsport conditions.
