Series 1, 2, 2A and 3 models
The distinctive extra lever on the right hand side of the transmission tunnel on a Series 1, 2 or 3 shows that it is equipped with a Roamerdrive. Since 2002 the majority of new overdrives fitted to these timeless vehicles have been simple rugged units. Proven in hundreds of installations worldwide, this rugged and well engineered product will improve the performance and economy of your collectable Land Rover. The SS model Roamerdrive is an auxiliary gearbox that is easily fitted to a Series 1, 2 or 3 with a 4 or 6 cylinder engine. The unit adds an additional 28% to the ratio of the transmission giving improved fuel economy. Reduced engine speed contributes to quieter more comfortable travel at motorway speeds and extends the life of drive train components.
The Roamerdrive is a completely mechanical device built in the same tradition of rugged dependability that has made Land Rover the world’s favourite expedition vehicle. These overdrives have no electronic or hydraulic components. They are engaged or disengaged by moving a convenient lever.
Unlike a high ratio transfer case that will permanently detract from the versatility of the gearbox, the Roamerdrive does not affect the vehicle’s designed gear ratios. The unit provides useful ‘splitter’ gears such as a gear ratio midway between conventional third and fourth.
The Roamerdrive uses the same epicyclical gear technology as a modern automatic transmission and is very quiet running. This is particularly evident at higher speeds and makes driving a Series Land Rover for long distances a more pleasurable experience. Fuel savings will depend on your driving habits. On long journeys Roamerdrive users have reported fuel savings of up to 18%.
