The Tractive RDT175 Concept

A premium quality gearbox with top class performance and functionality and low weight to a very competitive price. The RDT175 has a direct fifth gear and no drop gears. This will save cost and weight compared to a drop gear concept. The axel ratio must be altered to suit the top speed requirement. Easy adaptation to BMW, Ford, Opel and Volvo cars. Introduced in 2015, the RDT175 already has a track record of total reliability. Numerous rig tests and race condition tests have been carried out.
