Isn't a Slipping Clutch a Bad Thing?
No! In stick shift drag racing, a slipping clutch is actually quicker, more consistent, and easier on parts. Dedicated drag racing clutches, known as "Adjustable" or "Slipper" clutches, are designed to slip. This allows for more consistent launches, quicker E.T.'s, and fewer broken parts.
With The BangShift Billy, you don't need to switch to an adjustable clutch. You can use it to slip a diaphragm clutch!
Why Not Just Buy an Adjustable Clutch?
Fully adjustable clutches are very consistent and reliable in race cars. For many, this is a great option. However, fully adjustable clutches have several cons for street-driven vehicles. Those include:
Cost
Maintenance
Complexity
For these reasons, we don't recommend an adjustable clutch for street-driven vehicles. Click here to learn more about the pros and cons of adjustable clutches.

His revamped setup runs a Gen5 LT1 donor from an Escalade through a McLeod RXT clutch.
