Why GK-3

A full clinic day demands more than a consumer device.

A massage gun pushes. The GK-3 works the tissue.

Consumer massage guns move straight in and out. The GK-3 uses G5’s Gyratory Percussion and Directional Stroking® technology, which moves in multiple directions at once to mimic the way a skilled therapist works tissue by hand. The result is a smoother, more thorough treatment than straight percussion can deliver.

That same motion is what makes it useful in two very different rooms: as a soft-tissue tool that eases muscle tension and supports recovery, and as a respiratory percussor used to help loosen and clear secretions from the airways.

New in Gen 3.1

Three upgrades, asked for by the people using it every day.

Same machine you already know how to run. No retraining, no new technique. Everything below is a change to how it handles and how it's serviced.
A cable that moves with you. The redesigned handle cable flexes with your hand instead of fighting it, so the handpiece goes where you put it through a full treatment. Less strain, better control.
A handle holder that holds. A refined holder locks the handpiece firmly in place between patients, so the machine is ready to roll into the next room without a second thought. Nothing to catch, nothing to drop.
Repairs you do yourself. The handle and cable are now toolless to replace. If a part ever wears, you swap it in minutes with your own two hands. No service trip, no downtime.

QUESTIONS

GK-3 FAQ

What is the GK-3?

The GK-3 is an FDA-cleared therapeutic massager, a powered device with a handpiece and interchangeable applicators that delivers deep, rhythmic percussion to the body through oscillation. It serves two roles: a soft-tissue massage tool that works muscles and eases tension, and a respiratory percussor used to help loosen and clear secretions from the airways. It mounts on a rolling stand or sits on a desktop, and it’s built for steady, repeated use in clinics, hospitals, training rooms, gyms, spas and the home.

Who is it For?

Professionals and individuals both. Chiropractors, physical and athletic therapists, and respiratory care providers use it in clinical settings. Home users choose it for serious at-home recovery and pain management.

Athletic and sports: Ease muscle soreness and support faster recovery between sessions.
Chiropractic: A trusted complement to hands-on adjustment and soft-tissue work.
Physical therapy: Customizable treatment across a range of rehabilitation needs.
Respiratory therapy: Percussion technique used to help clear the airways.
Home care: Professional-grade relief outside the clinic, with no special training.

How is it different from a handheld massage gun?

Consumer massage guns push straight in and out, which is straight percussion. The GK-3 uses G5’s Gyratory Percussion and Directional Stroking® technology, which moves in multiple directions at once to mimic the way a skilled therapist works tissue by hand. The result is a smoother, more thorough treatment than straight percussion can deliver, and it’s one reason therapists have relied on G5 machines to complement their hands-on work for more than 50 years. That same motion is what makes it effective for respiratory percussion as well as soft-tissue massage.

What's new in Gen 3.1, and do I need to relearn anything?

No retraining necessary. Gen 3.1 keeps everything the GK-3 is known for and changes three things: a more flexible handle cable, a more secure handle holder, and toolless handle and cable replacement so you can swap a worn part yourself in minutes instead of sending the machine out.

It's built to order, so when will mine ship?

Every GK-3 is assembled to order at our factory in St. Charles, MO. The estimated ship date is shown under the price and repeated in your cart and order confirmation, so you always know where you stand. Orders are built in the sequence they’re received, and we email you if that date moves, in either direction. Need it by a specific date? Call (800) 237-1832 before you order and we’ll tell you straight whether we can hit it.

I'm a distributor, hospital or clinic buying more than one. Who do I talk to?

Email sales@g-5.com or call (800) 237-1832. Tell us your organization, quantity and timeline and we’ll quote you the same day. We sell direct as the manufacturer, so there’s no middle layer on institutional and volume orders.

Can I finance it, or use HSA/FSA?

Yes to both. Choose Affirm at checkout to split the cost into monthly payments, roughly $165/mo on a $1,975 purchase, subject to approval. The GK-3 is HSA/FSA eligible and is a candidate for reimbursement and distributor purchasing. Free U.S. shipping applies.

What's the warranty, and how do repairs work?

Every GK-3 carries a 3-year warranty, extended to the direct purchaser at point of sale. Register your device to activate it. Our in-house U.S. team handles service and repairs with genuine G5 parts. On Gen 3.1 the handle and cable are toolless, so the most common wear items you can replace yourself without shipping anything anywhere.

Does it come with applicators?

Yes. The GK-3 Gen 3.1 ships complete with the Deluxe Applicator Package, a full range of interchangeable heads for different techniques and body areas. Additional and replacement applicators are available separately.

Can I use it at home, or is it clinic-only?

Both. It’s built for clinics, hospitals, training rooms, gyms and spas, and plenty of home users choose it for serious at-home recovery and pain management. The control panel is intuitive and no special training is needed to get started. If you’re using it as part of prescribed care, follow your healthcare professional’s direction.
