High Amp

Powers accessories directly (up to 4 x 30-amp circuits). Choose this if you're wiring line locks, transbrakes, nitrous, lights, or anything that needs real power at the button.

Low Amp

Built for low-draw signal circuits (under 2.5 amps) like ECU inputs or relay triggers. Choose this if you're feeding a signal into an existing system rather than powering something directly.

Not sure which one your setup needs?

Looking for a wireless button panel instead of steering-wheel-mounted buttons? Check out The Billy Bar. It's built for roll cages, dashes, and off-road applications.

Billy Bar vs. Billy Button

Which one do I need?

Billy Bar

A mountable panel (roll cage, dash, console, door panel, rear firewall) for setups where you want dedicated physical buttons in a fixed location. Best for off-road rigs, race cars with roll cages, or any build where steering-wheel-mounted buttons aren't practical.

Billy Button

Steering-wheel-mounted buttons for drag racing applications where you need control at your fingertips mid-launch.

The BangShift Billy Digital Clutch Controller

The BangShift Billy Digital Clutch Controller

Slipper Clutch Performance, Zero Wrenching

Get the consistent, repeatable launches of an adjustable slipper clutch on your stick shift diaphragm clutch. It's dialed in from an app on your phone, down to the millisecond.

How it works

The Problem

A street-style diaphragm clutch either spins the tires, bogs, or breaks parts at launch. The fix is usually a slipper clutch, which means crawling under the car to adjust it for street vs. strip.

The Fix

The BangShift Billy installs between your clutch pedal and hydraulic release bearing, and lets you dial in slip and release via Bluetooth from the driver's seat, on your phone. Adjust for the strip, then adjust back for the street, with no tools.

Made in the USA

Every part manufactured, not outsourced. Trusted by drag-n-drive racers to shave tenths off their 60-foot times.

Why Choose BangShift Billy Products?

Why Choose BangShift Billy Products?

BangShift Billy was born in a garage, not a boardroom. Founder Bill Armstrong has spent years racing in the drag-n-drive community, wrenching on his own car just like the rest of us. Every product we offer, from the Digital Clutch Controller to the Billy Button, was built to solve real problems he faced at the track.

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!"

Dean Rock

"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."
