FAST Transmissions
The gearbox
your truck left
the factory with.
We stock FAST gearboxes complete — from 6-speed distribution boxes to 16-speed tractor units — plus the internals to rebuild the one you have.
Matched to engine and axle ratio
A gearbox is only right when it matches the engine, the axle ratio and the work the truck actually does. Every model in our catalog carries its matching engine list and full specification — so you order once, and it bolts on.
Unsure which unit is in your truck? Send a photo of the nameplate and we'll identify it from the casting and plate data.
