Testimonials

"So far, I must say that The BangShift Billy Digital Clutch Controller is a well thought out product! It's great to have the ability to either street drive or drag race the car without having to crawl on the ground to adjust the clutch. Just the matter of hit the gas and dump the clutch consistently every time!"

"Major milestone today @ Cecil County Dragway. Broke into the 8s with my 4,100lb stick shift. I shaved off over a half second from my prior PB due to The BangShift Billy. Today was my first day using his system. My 60’ alone was cut down by 0.15 from my prior PB and almost 0.20 from my average 60’ — and that’s only after making one change from my initial setting. So, I’m sure there’s more left in it as I’ve barely scratched the surface."

FAQ

What is The BangShift Billy?

The BangShift Billy is a hydraulic manifold that controls the release of a hydraulic clutch. It is commanded by our ECU and the settings are adjusted through our phone app.

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.
