Who it's for
The oven for a shop that is tired of turning away the big jobs.
The 6x4x4 is the top of our size ladder. It is the oven for a shop that is tired of turning away the big jobs, or sending them out, because nothing in the shop is deep enough or tall enough. Think full ATV and four-wheeler frames, large automotive and racecar subframes, and big industrial parts that need to go in whole and come out coated in one pass. If you have been eyeing a deep 4-foot oven, this is the one.
A working business tool · Model 6x4x4
You stop sending the big jobs out.
The parts that used to leave your shop now go in and come out on your schedule, not a vendor's.
The size on this page is the size you get.
The dimensions below are the usable space inside the chamber. Many makers quote the outside of the box, which reads bigger than what actually fits.
You can price a job the moment you own it.
Every spec that matters is printed on this page, so you or your electrician can confirm it fits before you buy.
It ships ready to run.
Wired, tested, and pre-programmed before it leaves our shop.
What makes a Silverback different
Twelve places we went further than we had to.
Every oven in this class looks the same from ten feet away. These are the build decisions you only find when you open the door, put a hand on the frame, or run it for two years.

R30 rockwool 6 inch top
The 6 inch top is filled with R30 rockwool, and it is standard on every one of our ovens.

R30 rockwool 6 inch top
The 6 inch top is filled with R30 rockwool, and it is standard on every one of our ovens.
Rockwool is the premium choice for insulation. Every oven with the 6 inch top is filled with R30 rockwool as standard, and that top covers about 30 percent of the oven's surface area.
It costs about three times what standard insulation costs. We use it anyway, because the top is where the heat goes.
Applies to
Energy savings per batch
A deeper R30 ceiling cuts heat loss up to 63 percent, right where the heat actually goes.
Detail 02 of 12
Energy savings per batch
A deeper R30 ceiling cuts heat loss up to 63 percent, right where the heat actually goes.
Heat rises. Natural convection pulls it to the ceiling of the oven, so the ceiling is where you lose it.
R30 rockwool in a deeper ceiling cavity against R11 in a shallow one is a 63 percent reduction in heat loss through the top. You also get a more consistent finish run to run, because the box holds its temperature instead of chasing it.
The 63 percent figure compares an R30 ceiling to an R11 ceiling, using published R-value data from insulationrvalues.com/fiberglass-vs-mineral-wool. It describes heat loss through the top of the oven, not a guaranteed utility bill.
Applies to
Recessed interior lighting
The light sits flush in the ceiling. Nothing hangs down for a cart to break.
Detail 03 of 12
Recessed interior lighting
The light sits flush in the ceiling. Nothing hangs down for a cart to break.
Fully recessed and flush with the ceiling, so the light can never interfere with loading or unloading. It throws light down across your parts, top to bottom.
The housing is reached from an access panel on top of the oven, so changing a bulb does not mean climbing inside. Each window comes with its own interior light and its own switch on the control box.
Applies to
Wraparound door straps
The latches wrap the corner into the frame, so the door pulls tight corner to corner.
Detail 04 of 12
Wraparound door straps
The latches wrap the corner into the frame, so the door pulls tight corner to corner.
The dual door latches connect to the sheet metal and the structural frame across the entire front and side of the oven, wrapping around both the front corner and the back corner.
When the latch is engaged it has the full strength of the oven frame behind it. That gives you a door seal that actually seals, and keeps the heat inside where it matters.
Applies to
Inside corner brackets
Top to bottom brackets tie the side wall into the back wall, covering the sealed seam. That is the triple seal.
Detail 05 of 12
Inside corner brackets
Top to bottom brackets tie the side wall into the back wall, covering the sealed seam. That is the triple seal.
We did not have to put custom inside corner brackets from top to bottom in our ovens. We could have squirted some high temp sealant in the corner and called it a day.
Instead the sheet of steel is overlapped from the back wall, so there is no crack to see through. High temp RTV sealant goes over that. Then a custom top to bottom bracket goes over it, covering the wall seam mechanically and adding rigidity. That is the triple seal.
Applies to
Easy reach handle
The handle is on the side of the door, not the front, so you are never pushing on a hot door face.
Detail 06 of 12
Easy reach handle
The handle is on the side of the door, not the front, so you are never pushing on a hot door face.
The common way to build an oven door is to put the handle on the front. That works fine until you are loading a part and the door starts to swing closed on you. Your only option then is to push on the inside of a hot door.
We mount ours on the side. You can grab the handle even when you are half inside the oven, without reaching all the way around the door.
Applies to
Riveted frame
Permanent rivets on every joining surface, on top of normal fasteners. It cannot shake loose.
Detail 07 of 12
Riveted frame
Permanent rivets on every joining surface, on top of normal fasteners. It cannot shake loose.
We do not just use standard mechanical fasteners. We take the extra step and install permanent rivets on all joining surfaces of the structural frame, on every Silverback product.
No loosening of the frame, for the lifetime of the product. Most others use screwed connections only.
Applies to
Stay cool control box gap
The box stands more than 2 inches off the oven wall, so the electronics run at room temperature.
Detail 08 of 12
Stay cool control box gap
The box stands more than 2 inches off the oven wall, so the electronics run at room temperature.
The control box is the heart of the oven, and it holds the most expensive parts to replace if something ever happens to them. Electronics last longer when they run cooler.
So every control box comes standard on a custom stay cool bracket that holds it about two inches off the oven wall, with an air gap behind it. The controls stay at ambient temperature and the oven lasts longer.
Applies to
Detailed oven trim
45 degree mitered face trim instead of butt joints, then a second piece over the miter.
Detail 09 of 12
Detailed oven trim
45 degree mitered face trim instead of butt joints, then a second piece over the miter.
Butt joints scream bare minimum. We chose to do more, because it looks better and it works better.
On a common oven frame the ceiling sits on top of the side walls, so butt jointed face trim leaves that seam exposed. That is heat loss and no added strength. Our 45 degree mitered face trim covers the seam completely and mends the ceiling to the side wall. Then a second custom piece covers the miter itself.
Applies to
Power cord included
The cord and outlet come with it. It plugs in, and it does not cost extra.

Power cord included
The cord and outlet come with it. It plugs in, and it does not cost extra.
If you need it to run your oven, it comes standard. We do not believe in making the basics cost more. You can add features, but we will not charge you for something that should have been in the box.
On the 30 amp models it is a NEMA L14-30 twist lock on 10/4 wire. The 50 amp models get the same treatment. It plugs in instead of being hardwired.
Applies to
PID controller with auto tune
Auto tune calibrates the controller to your oven, in your shop.

PID controller with auto tune
Auto tune calibrates the controller to your oven, in your shop.
A PID controller holds a precise temperature for a set period of time, with a built in timer. A basic thermostat swings.
Auto tune is the part that matters. It calibrates itself to your specific oven model in your specific shop environment, so the oven learns its own room instead of guessing.
Applies to
Warranty and support, in the price
Two year parts warranty and lifetime phone support. Nobody pays extra for either one.

Warranty and support, in the price
Two year parts warranty and lifetime phone support. Nobody pays extra for either one.
The two year parts warranty is standard and built into the price on every oven, booth, and combo. It is not an upsell at checkout.
Phone support on programming lasts as long as you own the oven, no matter how long ago you bought it. We help people who did not even buy from us.

From their shops
Real ovens, in real shops, from a real company.
“Just received my 5x4x4 electric oven and it looks absolutely amazing. Extremely well built, delivery was timely and professional, and customer service has so far been top notch!â€
“It was packaged very well. They told me they would ship it within just a couple days. Believe it or not, it actually happened that way.â€
“Thanks for the crazy quick and precise delivery. You guys went above and beyond to accommodate my schedule.â€
Every review here was freely given. We do not buy reviews and we never have.
Straight answers
The questions buyers actually ask. Answered on the page.
Is this company real? Who am I buying from?
Fair question, and a bigger one when the oven is this size and this price. Silverback is a real shop. Every oven is built and tested in our Illinois shop, our address is on this site, and the company is veteran owned. Call and you will talk to an actual person, every time.
Will it work with my power?
This oven runs on 240V single phase, the standard heavy circuit in most shops. It has four heating elements totaling 10,800 watts and draws about 45 amps, so it wants a 50-amp circuit, and it plugs in with the included NEMA 14-50 twist-lock cord. Everything your electrician needs is in the spec table above. Not sure it matches your setup? Call us and we will walk you or your electrician through it.
I could just build one myself.
You could, and on materials alone a home build can come out cheaper. The real cost is time and risk. A chamber this big is a lot of steel to cut, seal, insulate, and wire, and those are weekends not spent coating paid work. A home build is not engineered, tested, or warrantied. This oven shows up in 5 to 7 business days, wired and ready, with a 2-year parts warranty behind it.
Will it fit my parts?
This is the biggest oven we make, with a chamber 72 inches tall and 53 inches deep (inside usable space), built for the parts other ovens cannot take, like a full four-wheeler frame. Measure your longest and deepest part and remember the numbers above are usable inside space, not the outside of the box. If you are close, or you want something even bigger, call us. “Can you make it bigger†is one of the most common calls we get.
What is included in the price?
It arrives ready to run. The power cord and matching outlet come in the box, everything ships fully wired, tested, and pre-programmed, and a 2-year parts warranty and lifetime phone support are included at no upcharge. Add-ons are optional, so you only pay for what your work needs.
Do you help with setup?
Yes. Lifetime phone support is included: call for as long as you own it and we will walk you or your electrician through setup, programming, or a repair, no matter when you bought. Everything your electrician needs is printed on this page in plain text.
What is ramp and soak, and who needs it?
Ramp and soak means the controller steps through a temperature schedule on its own: it ramps up to a temperature, holds it (the soak), then moves to the next step. Most powder jobs cure at a single temperature, so the standard controller covers them. If you run multi-step cures like Cerakote, ramp and soak is exactly what you want.
In our line, ramp and soak comes on the Bluetooth Ramp and Soak controller, which you program from your phone. The other controllers, including the touchscreen, do not include it.
What does freight shipping cost?
Ovens ship LTL freight, and what you see at checkout is the carrier's price to move your oven to your address. We pass it on, we do not add to it. Most orders land between $300 and $400. Typical extra charges are a residential fee and a liftgate fee, and each one applies only if it applies to your delivery.
Everything ships packaged with sturdy plywood protective skirting, wrapped, and strapped for the road. If it arrives visibly damaged, note it with the driver and we will make it right.
Before you buy
Freight, warranty, and returns, in plain terms.
Shipping, in plain terms
Your oven ships on a custom pallet wrapped in plastic and strapped, with 48-inch plywood protective skirting around it. Two charges are added only when they apply: $70 for residential delivery and $70 for a liftgate if you have no dock or forklift. To see your freight cost, add the oven to your cart and continue to checkout. Transit is usually 3 to 5 days.
Warranty and support
A 2-year parts warranty comes standard on this oven. And you get lifetime phone support: call us for as long as you own your oven and we will walk you or your electrician through setup, programming, or a repair, no matter when you bought. Warranty parts are sent out once you mail the broken part back.
Returns
Cancel within 24 hours for a full refund; after that a 20% restocking fee applies. Returns within 30 days of receiving the oven carry a 20% restocking fee, you cover return shipping, and the oven must be in original condition.
If there is major damage, refuse the shipment and we will handle the claim, repair or replace, and reship.
