The EXTREME 3 Speed Stocklock is a new addition to the Stocklock family.

The new Stocklock “Extreme” transmission lock-up kit is a 3 Speed lock-up, and is much easier to operate as it is wired directly to the Sports shifter.

It has one button to turn the Stocklock on and off, and works the same way as the Dual Speed.

With the button turned on, the Stocklock will be automatic and engage around 78 km/h when in drive.

If you want to use the low speed lock-up, simply move the shifer to Sports mode and then you have lock-up in every gear from around 38 km/h.

With the shifter in sports mode and you activate LOW range, you will have lock-up from 8 km/ h.

If you don’t want the Stocklock on, simply push the button off, or move the shifter back to drive. It is that simple.

This new Extreme 3 Speed Stocklock is a fantastic design and I think will be the preferred option as it is just so easy to use, with the added 3rd speed for low range.
