- Hey, guys, Brad here with Custom Offsets.
Got another episode of "Lifts and Levels" for you.
This is going to be BDS four-inch system for 2014
to 2018 GM 1500 trucks.
This one in particular is going to be going on
this 2018 Chevy Silverado 1500.
This is the four-inch system.
It's got the new struts up front.
There's no spacers used in these systems.
But one thing that's special about this system
is the customer on this particular kit
opted for the complete replacement rear release springs.
So you'll see there's gonna be no blocks in the rear.
We're removing the factory springs
and putting in these new lift springs
and getting rid of the factory blocks, as well,
and just replacing it with this.
One thing to note is
these springs do not come with bushings,
but when you buy the springs in the kit,
BDS does give you bushings.
They use a poly bushing.
Not the biggest fan of a poly bushing
on a street truck like this.
Sometimes they like to squeak,
and it can get kind of annoying,
but they do seem to hold up, but only time will tell.
So we got the rear springs for the back of the truck,
and then up front, we obviously got our new
lift knuckles here, as well.
Four and six-inch kits use both the same.
Both of them use the same life knuckles.
Got our front and rear lower control arm drop cross members.
These are gonna be the same between
four and six-inch kits, as well.
Front differential brace, if you will,
which will go on the front differential
once it's lowered down, and then it'll tie
into the cross member here, your lower cross member here.
And then, let's see, we got some diff drops, as well.
This is gonna be one of the diff drops.
We'll measure this quick so you can see what we got here.
So if we go in the middle, this is tapered
so it's not gonna be a perfect measurement,
but about 4-1/2 inches on this for the diff drop,
and the other one's going to measure
I would imagine the same.
These just dirty from shipping here.
4-1/2 there, as well.
So the front diff is dropped 4-1/2 inches,
and these are all gonna be the same parts
between the four and six-inch kits.
So you'll see the four and six-inch kits
are pretty much the same except for
the struts up front are gonna be different
to give the six-inch kit obviously two more inches of lift,
but everything's gonna be dropped the same amount.
So you'll notice on these four-inch kits,
once we have it all installed,
the angles of everything are gonna be perfectly flat
and really nice where the six-inch kit,
you'll have about the angles you would
as if you had a two-inch leveling kit,
which isn't the worst thing in the world.
It's not necessarily bad.
It's just not gonna be factory-like flat.
Also, on these kits, track width is increased
on the front about a inch and 3/4-ish.
Let's see here.
They give you theses CV axle spacers.
These are only a plastic spacer,
not even an aluminum one or anything fancy there.
Got about an inch and 5/8.
I believe that what they say the track width is increased,
about an inch and 5/8 give or take.
It's not really too exact of a measurement,
at least that I know.
And then you got new strut top hats, as well.
So you will have to take apart the factory struts.
So that's one thing to know if you're gonna try
and do this yourself.
You're gonna need a strut compressor
to take apart the factory struts
and get the springs off of 'em
to put on the new struts in the rear.
Going with the standard NX2 shocks,
and we got some skid plates, as well, for the front.
This is gonna be the splash guard,
which will replace the factory plastic one,
and then these are gonna be the skid plates,
which tie in underneath the lower control
and drop cross members.
And then we got some new U-bolts
and a bunch of other hardware here, as well,
some bump stop relocation brackets,
and that's it.
We're gonna go ahead and get it installed.
Then we'll come back and check in on it,
run through the truck once everything is installed.
(man whistling)
- [Man] Did you measure anything?
- Just this, just these.
All right guys, we got the BDS four-inch kit installed
on the truck here.
We're gonna run through the components
as they are in their final resting position here.
So let's see.
We got the new BDS knuckles, as you can see here.
Also, BDS includes the new outer tie rods,
which is nice so you don't have to modify
your factory tie rods.
Of course, we got the new replacement strut here.
So you remove the factory strut.
There's no spacers or anything like that.
Use a whole new strut.
You have to swap the spring over, so remember that.
New sway bar end links, sway bar drop here, as you can see.
Another key component would be the differential drop,
which are gonna be these brackets in here.
As we measured before, it's about a 4-1/2 inch
or so diff drop.
And then you'll see the CV axle spacers
installed here, as well.
That's because the track width is increased,
meaning the front will actually be wider than the rear.
A lotta people will run spacers in the rear
to compensate for that, or a lotta people don't.
It doesn't really matter.
It's not gonna affect the performance
or anything like that.
It's more of just an aesthetic thing.
What else we got?
We got the differential brace, which is kind of,
you can't really see it here,
but it ties into both the cross members.
We got our skid plates for both sides of the diff,
and then the new splash shield here, as well,
which replaces the factory plastic one.
That's gonna be pretty much all of the front components
on this lift.
We will go around to the back
and show you something a little different.
Usually it's just blocks in the rear.
This customer opted
for the optional replacement leaf spring pack.
You'll see a brand new leaf spring pack here.
There's gonna be no factory block.
The factory block even gets removed,
and then we got the new U-bolts, as well.
These do come empty.
So you do have to put bushings in them.
BDS includes the bushings when you buy the springs
with the lift kit.
We got the NX2 shocks.
These are the base model shocks.
A lotta people go with the Fox shocks,
but this customer went with the NX2 shocks.
And let's see here.
Relocation of the brake lines.
You actually just bend this bracket up
to give you slack on the rear brake lines here.
That's about all you gotta do for there.
And then I believe that's about it.
You gotta kind of unloom the ABS wires,
the wheel speed tensor wires like that.
Take them out of the factory clip
so that those have room,
but really that's gonna be it for that, as well.
This is gonna be BDS four-inch kit
for 2014 to 2018 GM 1500 trucks.
Peace.
