Dog Box Kit

The race gear box for your Elise / Exige or 2-Eleven !

Worn out synchronizer hubs, -rings or -clutches as well as broken gear wheels will be a thing of the past if using this transmission ! The gear is designed for a load up to 450 hp and 400 NM torque ! Boundaries are rather set by the weak basis of the original box.

Gear ratio data – gears 1-6:
1. 3,002

2. 2,001

3. 1,502

4. 1,200

5. 1,001

6. 0,873 ; 6. gears with longer ratios are also available on request.

"final drive": 4,32 oder 4,62:1 oder 5,1:1

Included with delivery:

- Gears 1-6, incl. "final drive" and all shafts.
- the shift forks which are made from high carbon steel are also included with delivery !

In addition we approve the utilisation of a non-suspended clutch plate made from sintered metal, which can be purchased from our company, too.

We recommend this race gear box only for "race or heavy trackday use".
Since this transmission will be switched very fast, it is rather unsuited for "street use".
Furthermore the shift-related noise is higher in comparison to the standard one.

The price only includes the "dog box kit", without assembly !

The gear box can be mounted to an available transmission housing at our workshop. (Pls. see selection)

Besides we offer the complete assembly to your vehicle, pls. contact us for questions belonging to prices and installation times.
