manuals Manuals

Please feel free to use these manuals to help you get to know inside your gearbox better and increase your understanding of how it works and what you need.

We are slowly updating the manuals as most of them are from the time when these gearboxes were new and there have been updates and revisions from the original design. So please be patient if you are having to use one of the original ones.



(Please note the FT200 FG400, FGA and FGB share the same manual so please make sure to read the appropriate section for your gearbox.)

The racing of high speed and high performance vehicles can be a very hazardous activity and therefore involves a high risk of personal injury or even death.

1. By a driver with the requisite training, skill and experience necessary both for the conditions under which the products are to be used and for the racing of high speed and high performance vehicles
2. On specially designed racing tracks and under the supervision of official and approved racing organisations or otherwise under proper and reasonable operating conditions supported by appropriate safety, medical and rescue services
3. With proper maintenance and repairs effected to parts and gearboxes as all parts and gearboxes, being mechanical devices, are inherently subject to wear and tear, fatigue or disintegration and/or damage due to collision or improper use.
