Out at Dino's Git Down in Glendale showing off our fully loaded Level 3 airbag chassis built specifically for 1947-54 Chevy 3100 short bed trucks. Spencer breaks down everything from the Flaming River power steering to the LT4 motor mounts, Wilwood brakes, Currie rear axle, and Accuair E-Level Plus air management system.
This chassis lays frame on the running board brackets and comes ready for an LT4 with 10-speed transmission. Running 14-inch Wilwoods up front, upgraded 35-spline rear axle with 1350 U-joints to handle serious power, Falcon shocks, modular bolt-on design with grade 8 hardware, and powder coated in our signature FFG Grey with Casper clear coat for protection.
Everything's dialed in - stainless brake lines, braided fuel lines routed inside the frame rails for that super clean look underneath. Dual battery boxes, rear Watts link, all billet components. Built by Porterbuilt and fully loaded by FFG, this is the best foundation money can buy for a classic Chevy truck build.
This specific chassis is AVAILABLE FOR SALE right now. Buy it as a rolling chassis ready for your drivetrain ($39k without wheels/tires), or we can equip it with a complete LT4 long block with Whipple supercharger, headers, exhaust, and driveshaft. With the drivetrain package, we can have a full Designer Series painted truck done in about 6 months instead of the typical 9-12+ month timeline. If you're serious about building a classic Chevy truck the right way, this is your shortcut. Reach out to us before this one's gone.

Hey guys, this is Spencer with Fat
Garage. We're at Dino's Get Down at the
State Farm Stadium in Glendale, Arizona.
It's an all Chevy truck show. We're
having a great time. Sitting behind me
is one of our frames for a Chevy truck.
This is a level three airbag chassis and
it's designed for a 1947 to 1954 Chevy
truck, the 3100 trucks for a short bed.
This is our airbag chassis. So, this uh
lays frame or essentially lays on the
running board brackets. So, we have it
set up with uh the motor mounts for a
LT4. We built it from a long block with
a Whipple. If somebody wanted to
purchase this from us, they could get it
with or without the drivetrain package.
We'll sell it either way, but the motor
mounts are set up for an LT4 uh 10-speed
combo. So, from front to back, you got
your front sway bar, you have your uh
Flaming River power steering rack, motor
mounts for an LT4, as I mentioned. You
have your upper and lower control arms,
ball joints, you have your airbags. We
run an Acuare E- Level Plus Air Ride
system or Acuare Ultimate kit. That's
what comes with the the air tank and all
the compressors, everything like that.
Super super stout setup. We're super
happy with it. Um, you got your Falcon
shocks on here as well. We are running
14-inch wheelwood with disc brakes. Now,
because of the LT4, this chassis's had a
couple of upgrades. For example, the
rear axle's been upgraded to 35 spline,
1350 for that axle, so it'll handle lots
of horsepower. Um, you'll notice
everything is modular, so a lot of bolts
everywhere. It's grade eight hardware.
It's very sturdy. It's very rigid. Um,
but it's also means that you can remove
things if you don't need them or if you
need to adjust them. So, like your cab
mounts, running board brackets, that
heat shield area where you route your
exhaust, it's all bolt-on. So, if you
wanted to change something about your
setup or plans change if you've hot
rotted, plans change all the time. So,
back here, like I said, running board
brackets here, we run stainless brake
lines all the way down. And then we run
braided a fuel lines inside the frame
rail. The idea is, if you look under the
truck, it's super clean. You don't see
anything. This is powder coated. This is
our FFG gray. It's like a matte
charcoal. Then, we'll also put a layer
of Casper clear over it. That way it's
just extra protectant. Um, keep it
weather durable, that kind of thing. But
this is the air ride system. So you have
your your Endo air tank, you have your V
air compressors, and of course you have
your E-LE Plus air management system.
We've wired it all so it's connected to
the stand here. So just for a visual, if
I want to play with it and move it up or
down, it should be able to do it. So
back with the uh rear of the truck, it's
a 9-in rear axle from Curry Enterprises.
We run a rear Watts link. That's the
standard for us on all of our Airride
setups. All billet arms. Everything's
either billet or it's the standard steel
that we've uh cut and we welded as part
of the chassis. So, very high-grade
stuff. You have your big Willwood disc
brakes, calipers built to stop. You have
your battery boxes back here. You
typically run dual batteries with a
setup like this to both power the truck
and power the air management system. So,
that's pretty cool. Yeah. I mean, you
know, if there was a drivetrain in here,
there'd be a lot more to talk about. The
chassis is a little bit easier to cover
at this point. Best of everything. We
spare no expense. All of the uh
obviously the pennies stack up, but we'd
rather you have the best setup up front
than chase your tail over the next two
years trying to fix stuff as it comes
up. So, there's nothing wrong with like
the '90s Corvette spindles, suspension.
There's nothing wrong with Crown Vic. We
just like to take it to that next level.
And this makes things a lot easier for
us. If you're an at home builder or you
own a shop or you just want to get into
something like this, this would be the
easy way to kickstart this. Speaking of
easy way to kickstart, this one
specifically is actually available for
sale right now. You can either buy it as
is. I think it'll run about 44 grand
without the wheels and tires on it, but
we can set you up on some Gunny roller
wheels. But 44 grand, that's the best
bones money can buy and you're ready for
a drivetrain, exhaust, drive shaft, and
then truck can go all go back together.
Or if you want it, we'll equip it with
the LT4 long block. We'll put a Whipple
on it. LT4s are really hard to find
nowadays. So definitely for in our
opinion, if you wanted us to build a
truck, you're saving about 6 months on
the lead time just with a snap of your
fingers. LT4s already, Whipples already,
we would be able to throw this all in
with the exhaust and the drive shaft in
about two weeks. So, if you want a
kickstarter build, we could build this
thing as a full designer series painted
truck in, you know, call it a 6-month
time period. Um, compared to like a 9 to
12 plus month time frame if we're going
to do a full painted truck. So, if this
is something you're interested in, it's
a very easy way to cut the line, if you
will. Uh we had a customer that went a
different direction with this project
and um we worked out a deal with him
where we could keep it because we knew
that we could give it to another happy
customer that would uh would know what
to do with it and that's kind of the
goal for us. So reach out to us. Again,
this one's available, probably won't be
for long. Um you can either buy it as a
rolling frame ready for a drivetrain or
we'll supply the LT4 10-speed, run the
headers, exhaust, run your drive shaft,
everything like that. But in the
meantime, this is a full roller. It's
ready to go. We'll get some shots of it
airing up and down. But otherwise, I
think we've covered our bases. I'm uh
Spencer with FatFender Garage and this
is the best chassis on planet Earth.
