All right, today on a 2004 Ford F-250 long bed, we are going to install BestRail kit
part number 42730. One of the first things to do to prepare the rails is apply some camper
tape to the bottom of them which is supplied with the kit. There are three rails we have
to do this to. It is really simple. We will apply the tape to this edge here, over this
gap, and onto this ridge right here. We will just work our way back all the way down. Repeat
the same process on the other two rails. The next step is to slide three of the clamps
into each one of the BestRail side rails. Using an 1/ 8 inch Allen wrench, we are going
to install four of the 1/4 by 20 by 3/ 8 inch set screws in each of the corner brackets.
Next we are going to go ahead and take the front BestRail and place it on the front rail
of the truck bed. You want the foam tape to go ahead and lay
on the bed rail itself. We are going to slide the angle bracket into the front channel here
on the front rail. And the other side of it is going to merge into the side rail here.
And that is going to help connect them together. What I have done is actually applied some
white lithium here through the tracking just to help with the ion of the corner bracket
here. Now that we have got the side rails and the front rails attached together using
the corner brackets, we are going to go ahead and
set up the proper positioning by using
the corner covers here. What I
have kind of already done is adjusted the front rail
to make sure it is centered in between both sides of the truck. We are just
going to place the corner brackets on
top here.
