More Info

The T5 is a gearset suitable for the Borg-Warner T5 gearbox, capable of handling the “big grunt” engines.

A gearset that should address any inherent weaknesses of this transmission.


Short or Long?

Our wide ratio kit, has the ratios of the standard Sierra Cosworth gearbox: many clients run wide power band engines, and felt that close-ratio would not be a benefit to them.

The second gearset is close-ratio (pictured). This will suit high output normally aspirated, or generally narrow power band engine applications.

See the info box on the right for these ratios and more information.

We can supply this kit fitted to a gearbox on an exchange or outright-buy basis, fit it to your ‘box, or just supply the kit – contact us for more information.
